Hello all, got a tranny question for ya. I have a 91 grand prix with a 3.1L engine. I assume I have the 4t60 trans, but my questions are the tranny goes into gear fwd, rev, low 2,1 but the car will not move. Feels like something is locked up. Jacked the car up and spun tires by hand. Then put car through gears and no movement of tires. Anyone heard or have any ideas of the problem and fix?? Did notice cooling lines to radiator slightly leaking. My son put fluid in, and level is fine. I just hope he put the right fluid in considering it's hard to find dexron 2 or 3 anywhere. Any ideas or help would greatly be appreciated.
Thanks in advance,
