727 question
Ok. Hopefully they didn't drill the 2-3 shift passage very big as the Kevlar band has a higher coefficient of grip so with it overlap is more prevalent. Concerning the end play, most 727's are designed to only use only the bronze washer between the input and output shaft. The way you adjust the end play is with the selective thrust washer between the front pump and front clutch housing. There are different thickness of the fiber washers so you have to try them and see what gives you the right clearance. I shoot for .012~.015" total end play. The different thicknesses of the washers give or take a couple thous are .062", .075", .089", and .105".
BTW: make sure you use the .062" thick fiber washer between the front and rear clutch packs. If you need a different thickness selective thrust washer to get the end play in spec let me know as I have a whole box of them.
