Hi,
We just replaced our old TH350 with a new B & M TH350, the old one was working but was leaking like a sieve all seals were gone and it was slipping.
We installed the new TH350, with a 3000 stall speed converter & trans cooler. Now our problem is that the new tranny will only go in park, 1st, Reverse and Neutral, it will not shift into 2nd or 3rd gear. We have a B & M Quick Shift Ratcheting Floor shift that was fine with the old tranny.
Does anyone have a clue why it might not be going into 2nd and 3rd?
Thanks,
Mike
