The entire disc does not float, just the splined center hub. The next time you have hands on a spring center clutch disc, push the center around. There will be some axial movement that takes up minor miss alignment. A solid center disc lacks this free play and this contributes to spline wear.

Regardless, an auto trans is much less tolerant of concentricity miss alignment and will end up with a damaged pump bushing. This is because you only have a very limited amount if clearance at the bushing and lack of axial flex in the system.


I won't let bad info stand. What would help our guy is a posting of the actual factory procedure to align the plate.
