Hey guys, just got my new tranny installed today and now my trans temp and o/d off lights are on. Tranny temp gets up to 100* and the tranny will not shift into over drive. I got an ATS tranny from a guy with only 5000 miles on it, its out of an 01 my truck is a 99. Somebody please help me!!!

 

I know we got some Tranny guys out there somewhere.

 

Well this can be closed. Figured out the problem. Got to lookin real hard at things and unplugged the electrical harness on the side of the tranny. There were some loose connections in there. Tightened up the little deals and now A ok.

 

Congrats, glad it all turned out simple.
