    You need to go to one of the parts houses and ask them if they would check your codes on your engine and then come back here and post your code. That will help determine what the problem is. They will generally do it for free.

My 1994 GMC Suburban wont shift out of first.....but will shift to second manually but wont go any higher........?


Sounds like a vehicle speed sensor, it governs shifting based on engine RPM vs Transmission RPM among other things. Located usually on the rear tailshaft or rear transfer case on the majority of 4L60E automatics.
