I just had 3.73 gears installed on my 07. I heard about gear whine or slippage and I do notice something different in the way my car shifts and accelerates. I have an auto btw.

When I accelerate sometimes it will shift into 2nd or 3rd and then for a second it will stop accelerating and then a fraction of a second later it will pull again. Is this slipping? It doesn't happen all the time. How would I check for whine/slippage? What damage could be done from whine or slippage?

 

Gears don't slip. Do you have a custom tune for the 3.73?

 

Hahahahaa. I thought I heard people say whine and slip. Guess not!!! Yeah, I do have a custom tune for it.

I feel like an idiot

 

Your hesitation sounds like a tune issue or it could be the fuel pump tsb. It could also be traction control kicking in.

 

This is my guess.

 

need info on the fuel pump tsb you mention moosestang. thanks
