Despite the enormous amount of misinformation that is posted in this forum section by a certain individual, the excessive play has nothing at all to do with forward clutch pack clearance and everything to do with spring to piston clearance. And also, everything to do with total unit end play.
You likely won't notice the problem until it gets bad enough and the apply piston comes out of the bore, and then your forward clutches will be applied at all times. Again, with the piston popping out of the bore and inverting the spring, this is most common with high pressure valve body (up to 215 psi) racing transmissions.
In a stock application, with 70-80 psi line pressure in forward gear, you aren't even going to notice anything from the inherent excessive play. This is something that needs to be addressed in all racing and performance high pressure valve body combinations. It is also addressed in all of the diesel transmissions that we build.
