no reverse after being parked (believed to be a 700R4)
I have a 1991 1500 Suburban that was parked while I was out of country for about 1 1/2 years. I started it the other day and found that it doesn't have reverse at all. All the forward gears work as they should as well as the 4 wheel drive, but it feels like reverse it gone all together. Any help would be great. Thanks Steve
