Re: Differential problems

TH350 is not factory for a third gen.... So someone swapped the trans. Is it built?

What's your idle speed?

Re: Differential problems

Cable adjustment out of whack. What other things were "improved" when a TH350 was added?

Re: Differential problems

Define "jump".

A 350 cable isn't responsible for any of that, assuming that there's REALLY a 350 in the car. All the 350 cable does, is make it shift down when you floor it.
