727 Rebuild Advice

:burnout:Stock bands are fine,the front clutch drum is the snap ring you can replace with a flat instead of a waved.if you replace with a flat snap ring it will have a firm-harsh engagement into reverse.If it was my first time building a transmission i would build the unit with no shift kit to start off and install after you have a good working transmission.See a number of people install a shift kit into a fresh transmission then have problems,is it the shift kit or a internal transmission issue with a clutch drum etc.you can always install a shift kit later.Good luck with your build.:burnout:
