Tranny Problem...
Now is there a way to modify the 97 tranny to work with the 94 year model car or do you have to swap the entire tranny out?
Reason I ask is I am getting these two codes:
59 for tranny fluid temp sensor circuit high - low temp
81 for QDM or shift B solenoid fault
Thanks!
The 95-97 trannys have that pin but the 94's do not. Thats the only reason I can see these codes showing up is because the PCM being a 94 while the tranny isn't. The transmission is a brand new unit from GM as well.
If doing some programming on the PCM is the best way to fix it what is the best way to do this? just the dealership or a place that can do a flash on the PCM?
