Would a visual apply here as well?

What would happen if its too tight or too loose?


Facts and specs are important. I simply use a visual inspection as I build since I have done this tranny thing for decades.

.054 will work on a 3-4 clutch pack 700r4 IF you have a daily driver , low RPM application. If you are going to shift at higher RPM (above 4500) the clearance needs to be opened to .070 IMHO.

The 3-4 clutch pack can tend to apply centrifugally at higher RPMs. I often install stiffer springs in the aluminum drum to help hold off clutch packs at higher RPMs.

Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
