is there any performance rebuild kits available? for this transmission
to make it handle more power?
When I was shopping and gathering parts before I rebuilt my tranny, I asked many suppliers about heavy duty parts, not looking for high performance, just wanting the best stuff so my rebuild would be long lived. I wasn't able to find much. Transgo makes a shift kit that I used, but its for smoothing out gear changes, not for increasing performance. I'm happy that I put it in my tranny. I heard rumors of a heavy duty 3-4 clutch pack and a heavy duty one way sprag clutch, but no one I talked to could source these for me. After having one of these trannys apart, I really don't see where there is much potential for substantially beefing them up. They were designed as a light duty tranny, only made to handle about 120 foot pounds torque. The amazing thing is how small the package is, this tranny being a 4 speed with torque converter lock-up.
I may want to rebuild another one of these trannys some day so I am still interested in finding sources for the best and strongest parts available. Hope others can chip in with sources or suggestions for making these trannys stronger and long lived..
I've read about a five disc clutch pack that will fit in these autos, but I have never seen it. That upgrade alone would increase the torque rating substantially. Best upgrade you could do to increase holding power is to swap in a 5-speed. :|
I was looking around the web and found this site...there is some info on the 4eat..
