T56 hard to shift into 3rd after rebuild Just rebuild my transmission as part of a conversion from LT1 to LS1. It shifted perfectly before the rebuild and everything was in perfect shape inside.
The T56 was an LT1 unit, so converted the front plate & input shaft.
Used the gearbox.org Stage 2 rebuild parts, so new carbon fiber/kevlar blocker synchronizer rings, Bronze fork pads, billet keys, 3-4 steel shift fork.
I DIDN'T put in new synchro assemblies.
Used GM Dex 3 fluid.
Brand new SPEC Stage 2+ & billet flysheel.
Tilton master (same as Tick), bled the crap out of it.
The issue is that all gears shift well except 3rd. If I ease it in it will go without grinding, but if I try a quick shift it grinds.
Should I proceed with a 500 mile breakin and hope it works in, or is this more serious..like tear it back down?
