Just completed Tremec 56 rebuild on 97 FB - did not replace 3-4 shift fork with a steel - 4th locks in great - all syncros replaced - 1-2 syncro assy and reverse syncro assy replaced - Problem exists on both upshift and downshift -any suggestions ????

 

I had mine rebuilt recently and it does the same thing. Im just took it out to take it back i hope they waranty it. By chance does it feel notchy when you shift?

 

No notchy feeling is present and dead engine shifting feels right. However, fourth seems to have different stick travel from neutral to 4th lock in than neutral to third. My minds eye is seeing the outside of the syncro assembly more toward fourth than third when I put this back together. In fact, I questioned my parts source about the need to go with a steel 3-4 shift fork when I ordered my other parts and received a probably don't need to response. Also, after questioning the previous owner, they admitted the same problem. Possibly from hard shifts at the end of the quarter going from second to third may have tweeked the fork.

 

Anytime you tear a T56 apart and it does not have a steel 3/4 fork, invest in one. The cost is so minimal that it would be a waste of time and money not to. Did you invest in any other upgraded parts? Billet Keys, Fork Pads? That would be some other things to invest in if you have to tear it down again.

Hey Ls1Joe where did you learn how to work on t56s?

 

Thanks for your response - you are absolutely right as hindsight speaks regarding the, should have done, steel 3-4 shift fork replacement. I did go in with a full carbon fiber syncro set with brass on the reverse, billet keys and fork pads from my parts supplier. Thanks again.
