Anyone else have transmission problems at about 100,000 miles?

I have a tranny problem as well. this car has been great until now. milage is 98k and the shifting from 1st to 2nd is sluggish. used the rendezvous to pick up my granddaughter and on the way home and at a stop sign the car would not go. had it towed. i can move it in my driveway, no problem. went to tanny mechanic and he said from what i told him that it sounds like a risister. if that is the problem he said that the computer receives false messages and everything goes down hill. it sound like an easy fix. i am also contacting buick as well. i'll keep you posted. 2003 buick rendezvous cx

Thank you very much. The Rendezvous is showing on the computer it has tranny problems but it is still driving. We will drive it until the tranny "falls". Thanks :)

my car also has same problem (shifting anf slipping)...I did many way to fix but still same problems. If any one experienced to fix please tell us.

My car is having transmission problems, it's slipping when you take off at low speed. Sometimes it jerks and pops. I have 92,000 miles. I took to GM dealer and they hooked it up to computer and some code was at "5". They reset and had me come back in a couple of weeks and it was still reset. No error reading. BUT, car is still hard shifting. My brother had me check the transmission fluid and it was black (guess that means when you take your car for oil change and they say they check all fluid levels they must not be doing this). He also had be put some BG transmission fluid in. I think it has helped but still having problems. When back at the dealer to get the AWD disable, service trans. and antilock brake lights problem fixed I mentioned that it was still shifting rough. They said without a code I could spend a lot of money trying to find the problem and may not fix the problem. Guess I'll just keep driving until it stops working. Sounds to me like this model Buick has lots of transmission problems, good reason not to buy another one.

FiRendezvous Ultra w/ 94k miles. Car not moving in D or or 3rd gear. Will trave in 1st or 2nd if starting slowly. Was told that sensor that controls sh!ifting needed repl. and some main shaft? internally needed repl. Repair cost estm. $2500. Reman trans. $3500. Car worth 7k. GM you need to bump your game on quality of drivetrain before I buy another car from you.

I have a 2003 & reverse has went out in the trans everything else works fine I don't know whether to have the trans rebuilt or get another trans I was told the king pin broke is why I have no reverse. Has anyone heard of this or had this problem

Yes, my 2005 Buick Rendezvous transmission started to jerk at 95,000 miles. It slips when starting off and sometimes jerks when starting off in drive.

Ck for tranny sensor. If bad trans. Still shifts but with higher pressure causing slippage and trans. Rebuild

I also have 2005 rendezvous and a little over 100k miles and my car had been shifting very hard. Also very sluggish as I try to go from stopped position had anyone found a solution to this yet?

My Rendevous developed Tranny problem at about 98k miles, took it to Transmission shop , they wanted $1600 to fix it, A short while later I heard about Lucas No slip, I changed the Transmission fluid and added a bottle of Lucas, no more problems-

I have a 2003 and it is starting to jerk can anyone help me?

I tried the lucas fluid, it helped a LOT but not perfect yet

Hi Shasin, well my Rendevous is not perfect , it is starting to jerk a little but I am not going to worry about it, I have driven about 10-15 K miles on the Lucas, I am very happy with that Product.

I have a 2003 rendevous ultra and 151000 miles and when you go to take off it hesitates then the tranny completely went..only would drive in the 3 . My mechanic put a new tranny in and it's doing the same thing

I have a 2006 Rendevous with 111000 miles on it. Transmission slipping and clunks. Doesn't do it all the time. First time to dealer it didn't do it and computer said all was fine. Took it again when it had been clunking all day, they said it was transmission....we knew that. Anyway, $3400 for new transmission, is it worth it? Will it fix the issue? Cheaper than a new car.

05 rendezvous cx fwD mine was shifting hard after first then would jerk bad and did not want to go. It didn't do it all the time just some times . Done some research and found out it was torque converter shift solenoid 35 dollar part available at my local parts store ABC part number TCS 39 and I went ahead and got the two shift solenoids part # TCS 44 total 88 bucks for the parts and a bottle of lube guard platinum. I replaced them myself these are located on the side of the transmission it's a good 4-6 hour job. Look at YouTube there are some good videos on how to do it. Also some have been the speed sensor location is closer to the passage side underneath on top of the tranny a 24 dollar part. I heard that some changed the transmission filter and addeD that lube guard and it stopped after a while of driving . Hope this helps you out

So does anybody else try the bottle of lucas for transmissions does it work

My 2007 was slipping - changed the transmission fluid and it did great for a couple of months. But now it sometimes jerks in first gear. 97,000 - I have really enjoyed this car but not sure I will buy another if at 90,000 you have to have a new transmission.

Add a quart of Lucas No slip, it should solve the problem, I had the same problem you have , added the Lucas no more probrlem , give it time to work, but it should cure your problem.

its not a definite fix, but it postpones the problem, makes it still driveable I had to add 2 bottles. It seemed to drive OHKAY most of the time but the problem was still certainly there. Sold it to be rid of it.

I have a 2007 Rendezvous with 111,000 miles. Tranny just started to shift a little hard into 2nd gear, and a hard jerk and sound into 3rd gear. 4th gear no problem. Plus, I noticed the tranny is making a continuous sound, maybe the whine people have referred to, like something isn't right. I'll try the Lucas stop slip.

Robert I have a 2005 rendezvous with 160000 miles on it change oil every 5000 miles also chang trans fluid every 50000 miles never had a problem yet adding oil additives always don't help problems keep up maint on car is best answer my father was a mechanic for 33 yrs before he retired

easy fix, the Solenoids , in the Transmission need replaced. Those are located on the drivers side, remove drivers wheel and you will see the side cover of the transmission, inside the cover house the shift solenoids as well as a shift pressure plate. if you take your time, and go slow you can replace them. I my self have to do this to my 2002 Rendezvous. takes about 6 hours to complete, thus going slow so that you do not break the wiring inside. You will have to jack the auto up, placing stands along the rails, not the carriage. remove the drivers side wheel, brake cal, and shaft . empty the trans fluid . you will also need to remove the two carriage bolts, have a extra jack to do this. to keep the transmission in place, lowing it as needed. remove the cover bolts and then the cover. first remove the pressure plate, then each shift solenoids, replacing each one as you go along. each one is held in place with a U ring, try not to break the ring, because you will need to reuse it. last replace the pressure plate, replace the cover, use some RTV black hi temp sealant, to , to help seal the cover back, I do not think you can get a replacement gasket for the side cover. what is happening with the slow shift, is a solenoid is stuck open, chip out of the black ring, or even a broken ring. once this happens it cause the fluid to run thru it, there for causing a miss function of the solenoid . make it work slower or even fast then it should. if you do not feel like you can do it your self, then take it to a repair shop, that does transmission work ONLY. do not take it to a auto repair shop. you will get the best work by going to a transmission shop, that does work on transmissions daily . they know there stuff. a auto repair shop knows there stuff over motors or other, but not the best for transmissions, unless they have done the work before, research the shop, ask question about transmissions, then go to a transmission shop and ask the same question`s .. you will get the best answer from a transmission shop, cause they know transmissions better then anyone else ..

The Buick Renezvous all have a issue with the transmission. only because of the Transmission used, bad solenoids .. the gears and other working inside are good, they just had a issue of bad run solenoids for the manufacturer of the solenoids.. it happens, plus solenoids , unlike old style transmissions that have only gears, are mad to fail after 100k miles in all auto`s. some are better then others in how they are made and what they are made with. Its just Buick Rendezvous got stiffed for the solenoids. when they was made, the manufacturer of them, made alot of them in a short time, and Buick got shipped the low end of the parts when they was made.. Would be my guess, not real sure thou .. teh buick and the aztec are in fact the same auto, just different body styles, they use the same motor and trans, in them .. just one is made by Buick line and the other is made by Pontiac line.

Randal, I have a 02' Rendezvous that was drawing out the shifts. I took it to a auto place and the cooler lines had pin holes in them and it was 5 quarts low. They fix that for me and it ran fine except shifting into 4th gear that would tend to long draw only sometimes. They checked the solenoid's 4th was not pushing the right psi, so they recommended it to be replaced. Last two days it started jerking into gear, making a whining noise on the driver side, gears started drawing out then shifting. Then pow tranny just stoppedas I was driving. Rpm's go up but no go in all gears. What does that sound like to you Randal? HEEEEEELP.

Long Draw shift, could be a few things. I would start with replacing the Shift solenoids , then go from there, also replace the filter and Use high mileage fluid, try not to add any shift help or anything like slick 50. they dont always help the issue, they can cause build up over time.

if replacing the solenoid`s dont help, then a tranny shop is the next place to head too.. Or if you a good and want to rebuild your self to save 800 - 1001 or more . then you can get a rebuild kit for around 400, it wont have gears that might be needed, but it would be a great start to a rebuild. Or find a used one from a scrap yard that you can get a 30 - 90 day warrenty with.

I have a 2004 Renezvous, Never had no major problems with. No slipping or anything. Yesterday while driving something didnt seem right and was hearing a noise I never heard before. All of a sudden my car wouldnt go, wouldnt shift or switch gears, Wouldnt go past 5 mph, The rpms would move and go way up and it would jolt and jump and make noises if you hit the gas just a little to hard. Never had a problem like this before.

Could it be the solenoids like you were saying?

you know could be, just that. Rumor has it that with the Tranny in the Buicks and other. the Solenoids, that was put them came from a bad batch back when they auto was made. I have not found anything stating just that. but from what i have heard from other`s that have the auto with this type of Tranny in them. at around 100k they all start having the same issue, with long shifts, jumpy at 30 miles an hour. and talking with this tech and that tech and also they local transmission shop`s around my area. Seems that most are just a Convert solenoid that goes bad in them, or shift solenoids. one or two was pressure plate inside the tranny. and from what the techs and shops have said, in order to fix it and make it right is to replace all of them at one time. on a few case`s the shift solenoids or the convert solenoids that have went bad, ended up causing the clutch packs to go bad. so i can not say start with solenoid replacement, from my self. but rumors and talks have pointed to just that. But i always told my family that if there is a issue with a tranny, find another one or rebuild the one you have. replacing everything. cause in the long run, it might end up fixing everything at one time, instead of replacing this, something else go wrong, and having to rip in to it again, and fix the next thing. but that is just me, i dont like spending X amount of money on just labor each time.

Chris, to get back to you, on your problem. Sounds like the drive gears inside the tranny have faulted. meaning , the teeth on them have lost its bit. that is most case, but with these tranny the automatics in gen. Clutch packs, have lost there hope. each gear has it s own clutch pack set, they are mostly all the same, But each have there own draw for the pressure. unlike a manual shift, that uses one clutch plate, a automatic use`s 2 or three depending on the tranny.. with it just going out, like you say. tranny rebuild would be best or even a replacement from the local scrap yard. they are some whart easy to work on, just gotta have the room and storage bends for the parts with labels on each. a rebuild kit from Autozone or O Reilly`s auto runs about 450.00 the cheaper kits will not get you everything you need to rebuild, so before even going thru with spending that much, if the auto is not a must have, and another is at the ready to drive while this one is down, and you want to rebuild the tranny. then start with removing it taken it aprt and looking at each clutch pack, for wear. on them, but before that, empty the pan, and look close for any metal in it, a small amount of metal is normal, a large amount of metal, then look at the clutch packs and the gears inside the tranny when taking it apart. fine shavings is most likely from clutch packs, bigger or chunky is more leaning to gears. so look and watch closely. and be careful to label and draw out each part, bolt placement when in side. I find that drawing out each placement, will give you a better ideal and keep it easy when putting back together. instead of placing this bolt here and that bolt there.

My 2003 Buick rendeZvous, on the highway home from work, stopped driving. The RPMs started jumping without the cars accerlerating and when I got out of the car I saw a leak that I can't distinguish between oil on tranny fluid. Someone inspected my car and saw my dipstick tube for tranny fluid is loose. I changed that and now the car still starts but will not change gears or move...upon starting and attempting to change gears the car would emit a strange low squeaking noise that sounds related to the leak. My car has no fluid but when I put it in it leaks bc , at the suggestion of another mechanic, my tranny is shot. I don't think that's the case bc the car still starts. Does anyone have any words for me this is a real struggle and I have very few options in mind. Thanks i advance for any help

diff tranny, the tranny has nothing to do with the auto starting. the tranny is the go power for the auto. with out a tranny that works it will just set there. The auto guy is right, needs a new one, or that one that one rebuilt, Ether way, you might be looking at 800 - 1400 to rebuild, but a new reman one moight run you 1500, but the thing is with remans, i dont think alot of those comes with Solenoids or other items needed. I might be wrong ! If going with a reman one, check with what all it has inside of it. If rebuilding that one, you will need a Rebuild kit, that include`s all gaskets, Clutch packs and snap rings, the kit will run just around 475.00. then adding labor to the cost at say 50.00 a hour and there is just about 10 hours in rebuilding it. then if the solenoids are good along with the speed sensor. that about it, if not add another say 300.00 to that Plus fluid. On the plus side, rebuilding the one you have has its plus side for sure. Its local, and if any problems with the rebuild, you do not have to send it back to the company that rebuilt it. so save some time of about 2 weeks, in the long run. What had happen was, when the fluid leaked out, it caused the tranny to over heat and burn clutch pack and gear out. so if you rebuild or replace with a reman, use a external cooling rad. to helpn with cooling of the tranny fluid. you can still use the radiator in the auto to cool, ut on the return back to the tranny is where you want to add the ext cooler. adding the extra cooling will help the fluid last longer and keep the tranny cooler as well ..

Oh man I definitely don't have the money for that. I guess I'll probably be scrapping it then. But hey thanks a lot for your help at least from here I can plan out my next steps!

sorry, but there is a cheaper cost way. find a good one at scrap yard. might be able to pick one up from any were around 250.00 to 375.00. then labor cost might run you 300 or 400 ..

a service bulletin from NHTSA for many gm 2001-2007 these transmissions have a bad second clutch pack . 1-2 shift shudder. under light to moderate acceleration THe fix is to replace the 2nd clutch pack but trans has to be taken apart or maybe heavy acceleration but be careful

I I'm having problems with my car its in park and I can push it and when I try to shift it it grinds and nothing I have no gears can u help please

ok, Kinda like when you grind the gears on a stick shift kinda sound when you miss shift or do not get the clutch pressed in all the way. If that is what you are hearing, then the gears inside the trans case, are not connecting with the main gear. This is the more costly repair. as to the clutch packs. I would get the auto to a trans shop, and have them really go thru it. But to me this is what sounds like a full rebuild or full on replacement job .

Yes...my Rendezvous had transmission problems so bad that 2 mechanics said it was shot. Totally. Well, that was 30k miles ago and it works great at 130k miles. I drained the lower half of the trans and replaced the trans filter and pan gasket. Filled it back up then ran it. Still had problem but not as bad. No slipping, just shifting problems. Next, I drained and flushed the entire trans and refilled it plus added Lucas Transmission Conditioner. Ran it on the freeway for 50 miles to get everything flowing. It got better immediately, but it took a week for it to get back to working right. Now it works better than it has in years. I just have to warm it up for 5-10 min when its cold in the morn. Works fine. When its cold it takes a bit to shift into reverse or drive from park is the only issue. Only when its cold.

My ex-wife has a 2003 Rendezvous with 170K miles. The transmission was sluggish in shifting into all forward gears from a stop. The fluid was brown when checked on a paper towel but black when the pan was dropped or even a small amount put into a small 1 0z container for viewing. Sad thing is she took it to Firestone specifically for the shifting problem and then they sold her on $2,500 of other work but did nothing with the transmission. It is at very high risk of failure!!! As soon as I saw the fluid I knew the gravity of the situation... Burnt fluid on a transmission acting up. Jeesh, tell her to go to the transmission shop from the get go before spending money anywhere else since that one problem in its self has the potential to put this vehicle in the salvage yard due to repair cost. Any way yesterday (3/7/16) We dropped the pan, gave it a day to drain and I even have a power blower to force air into the transmission dipstick tube to try and get all the old out. Today (3/8/16) we replaced the pan, gasket and filter. Once that was done we started it out with Lucas trans. treatment, new tranny fluid and 1/2 a bottle of SeaFoam Transmission treatment. The vehicle goes into all gears thankfully. It did not have immediate improvement but we are hoping for continued improvement (perhaps clogs or obstructed flow passages will open up)???, Time will tell. If anyone wants to know how things fair out with a little time just ask and I will share. I had considered harvesting transmission fluid from a parts or salvage vehicle with 80 to 100K because of the worry of transmission failure post introduction of new fluids on the high mileage transmissions. That the cleaning affect of the new fluid may disturb sludge, cause leaks and immediate failure or shortly afterwards by having all this cleaning action taking place. My thoughts were to get a better fluid where it still does the performance job in gear shifting but the cleaning action is hopefully subdued from general age and use. I am sure I will try that later down the road on something else. On this model specific transmission my mechanic felt going with the new fluids along with additives was ok ***ONE IMPORTANT NOTE: THIS WAS THE EASIEST TIME I HAVE EVER HAD DROPPING A PAN AND REPLACING IT ON A VEHICLE, ABSOLUTELY NOTHING IN THE WAY! ONLY AROUND A DOZEN BOLTS ON THE PAN TO REMOVE... NO CROSS MEMBERS OR ANYTHING ELSE TO GET OUT OF THE WAY AND THAT IS NICE!!! ANYONE WITH GENERAL, REASONABLE MECHANICAL OR FIXING APPTITUDE, THE PLACE AND THE EQUIPMENT LIKE FLOOR JACKS, RAMPS, JACK STAND AND SUCH CAN DO THIS JOB, IF YOU HAVE NEVER DONE IT BEFORE JUST WATCH A VIDEO OR READ UP ON THE "IN GENERAL", OR "OVERALL" THINGS INVOLVED WITH IT LIKE NOT FORGETTING TO PUT THE FLUID BACK IN IT BEFORE GOING TO DRIVE IT, USING MOTOR OIL ON THE TRANSMISSION AND STUFF LIKE THAT! LOL... Or pay someone you know who deals with stuff like that $50 for doing it. No big deal doing that job. gpaarman@yahoo.com or (816) 337-7147

Buick Rendezvous Shift Cable Bushing Repair Kit . Copy and paste the 7 word description at the beginning of this post .

There are directions on how to install this item on You tube .

Hey my wife got off work and went to start my 2006 buick rendezvous. And once it was started she went to put it in gear. Now here's the problem. The shifter move freely. And it's not engaging in any gear it just moves freely... Could the shift cable bushing repair kit fix this problem. My transmission has shifted a little funky at times but it got her to work fine this morning. So I'm not sure what the deal is? Anyone have any ideas? Randal do you have a clue about this problem?

Oh sorry I forgot to mention that the Buick Rendezvous has 160000 miles on it I bought it about a year ago with 135000 miles on it

could be bushing, honestly i gave up working on mine, SOld it and bought a 2006 saturn Vue. with the Buick Ren, anything is possible at this point.. best thing to do, is track down the shift linkage, and go from there. Climb under it, with it up in the air, and feel under the body of it above the tranny . if the linkage feels lose, then it is the bushings, start it, with the wheels off the ground, make sure all four are of if it is a AWD. put it in to gear and then if the wheels dont move, spin them by hand be care ful, if it engages and the axels spin freely, then repair shop. But check the linkage before you do anything, as putting it in to drive with the wheels off the ground and even started. Sorry cant give ya anymore information on tracking down the issue. But could be a starting point for you ..

Thanks man i appreciate it. I'll go up to where is setting tomorrow and check it out done more. Thanks again.

I have a 06 Buick rendezvous and after taking a short road trip its humming. Only when I push on the gas not when I'm just sitting but it seems to be getting louder. Almost seems like its not shifting I'm not sure. Anything you can think of?

EVERYONE -------- DO THIS FIRST !!!! Please check your Transmission Fluid. If the fluid is very dirty it will cause transmission problems. There are so many times that I have had a car come in with dirty fluid that would not shift or would not shift properly.. You should be changing your fluid at least every 50,000. I hope this saves many of you a transmission replacement. A lot of shops will simply say it needs an overhaul $$$$.

I have a 2005 Rendezvous, Do not now the model at this time. I think CLS. Was having slipping issues and hard shifting from 2 to 3rd. Took to shop and had it rebuilt. They DIDN'T replace the PRNDL switch(neutral safety switch). Was causing a starting issue. Couldn't tell if it was in park, so wouldn't start. Turn key dash would light up but when turned the ignition went dark and NOTHING.. Tranny shop (at there cost) put in the new switch. That was the second time I had it there. Pick it up a couple of days later and was making a noise like a bearing went out in the trans. They towed it to the shop(there dime). It had a bushing in the torque converter out. They replaced and I will pick it up tonight. Been three weeks getting this thing right! We will see tonight if all is well. I have had nothing but trouble out of both Buick's I have owned. Not a GM thing it's a Buick Thing. 20 or more years between the 2 cars and both are front wheel drives. Their tranny's SUCK!

Trans code is 1819 and 1825 for the neutral safety switch. They have to hook it up and look for the codes. It won't show in the OBD. they have to ACTUALLY look for the trans codes in the cars computer. Thats how I found the Safety switch. Thought it was an anti theft thing. The Chevy tech was cool and let me back there with him. Was going over the key switch and the transponders. He plugged it up and LOOKY there he says. Threw both codes but no dash light.

I had the same issue would only show in 2 gears on dash. Wiring harness rubbed through under computer box. Double check before you pay to replace saftey switch.

I also had sluggish take offs and slamming into gear . Replaced selinods in drive way definitely 4 out of five wrenches. Put back together trans stuck in 3rd gear high pressure. That's when I found wiring harness issue. Repaired wires trans runs like new. Cost me 8 hours of my time and about 250.00 $

I have a 02 Buick rendezvous I have replaced both rank shaft sensors that keep tripping my engine light also had to replace my transmission cooler cause it was leaking, It is doing a bit of a kick back thing even though they added transmission fluid. It feels like the ass of my car is dragging a bit. The gas pedal feels heavy it doesn't seem to want to go up to 50 km/h very well. My traction/ABS lights come and go but lately they have been staying on. And now my change oil light is on when I just changed it a couple of months ago. One mechanic keeps telling me to just drive it or to replace my transmission. The Transmission guys want to service my transmission and add a conditioning to it. What Should I Do?

Honestly, Part with it. I had a 03, and the tranny was messed up. we got rid of it, These autos are more less junk, sold with crappy tans. Best advice to you is to part with it, while you can and before you go dumping 1200.00 - 1800.00 more in to it just on the tans alone.

Mine does same thing when ur at a stop put it in 1st gear manually...after u hit about 20 mph shift back into drive...if it doesn't do it anymore its the trans filter needing replaced

How much transmission fluid does this take?

Transmission problems around 150,000 miles. 3rd gear was the first to go. Drove it for three or four weeks with third getting worse and worse. Had it rebuilt for $1,400 in Texas. I'vee only had it back 2 days seems to be running fine
