trans wont shift into 3rd on its own
trans wont shift into 3rd on its own i swapped a 6.0 into my 98 z28. i kept the same 4l60e. i took the car out to start tuning it but the trans wont shift into 3rd on its own. i am getting a p0875 (3-2 shift solenoid) trouble code. i can shift the car into 3rd using hp tuners. i also checked the eng crtl fuse it was good. what else should i check before i drop the pan and test the 3-2 shift solenoid?
