fuel / tranny

Fuel pressure has no bearing on transmission function. What exactly is the problem?

The only way the fuel system has anything to do with the transmission is when the engine doesn't run. What makes you think they share a problem?

I thought my tranny went bad, sent it to the a shop. he called my and said the tranny is fine, problem has to due with not enough fuel to engine and computer is shutting down transmission

You need to fix the problem then. Is this the diesel? If so check the filter and fuel pressure.

engine was running fine when (I thought tranny) went, sat for 4 months b4 going to shop

can fuel pressure cause trany to shut down?

yes 02 2500 cummings diesel

Like Mike says if the engine does not run then nothing works. If it barely runs you will still have all sorts of problems. Sort out the engine and see if that helps the other problem.
