Jusst replaced trans with a used one 4t60e. I have to rev the enging to pull out. Once going it does fine, shifts good. Reverse is good. It also blows the fuse to speedo and other. Any help will be appreciated. Jim

How about make model and year of vehicle. Why was the original replaced? Miles on the old one. Who replaced it, you, dealer, Chain transmission shop, independent mechanic etc.

Check for harness damage,stretched during removal,pinched during install

The car is a 1994 Chevrolet llumina euro. The mileage is unknown. Was replaced because my son ran it dry of trans fluid. I did the work myself.

Automatic Transmission?
