A few weeks ago I traded my bike for a th400 that I was told was rebuilt.Just a few days after that I traded the th400 for a super t10 4 speed and factory firebird shifter attached.It has 3 rings on the input.This trans will be going behind my 383 that should have around 475 ft/lb.Ive been told I should have used the th400 but my car is already setup for manual and I think 4 speeds are better for street anyway.Is there anything I can do to beef up the super t10? Ive heard of people putting a steel plate in the middle bearing retainer,where do I get one of those? Ive been told you can put a strap around the case to keep it from stretching,how do I do that? If theres anything I can do to make this transmission stronger fill me in on it,Im wondering if theres a way to heat and cool the gears many times to stress relieve them.Anyway,what can I do? Is the super t10 worth more than the th400? I hope I didnt make a bad trade.
