Hi

Ivé had my transmission rebuild, I had no 2nd or 4th gear.

Now I got a slipping 4th gear, 1st, 2nd and 3rd are all fine also the lock up works fine, only the 4th gear is slipping, what could be wrong?


This is an 4L60E 1993, chevy pick up truck, 4x4.

Could be= overrun clutches are applying due to a cracked or leaking forward piston. Overrun clutches will be worn out after 30 seconds of this behavior. Car can be safely driven in D. R&R.?
