Rebuilt 727 no reverse took off pan help

I have brainstormed 2 plans I can go about on this issue, well technically if I really want to spend money lol


A. I install a bullet servo and fix that whole rear servo and band issue while I while I rebuild my other 727 and once it's ready I just swap them.

B. Rebuild my other transmission and not even bother with the one in it right now even though I just bought it that sucks.

C. I try to swing buying a crt transmission without my wife knowing(most dangerous plan) lol
