727 rear clutch problem
Hi, I have a '69 superbee, and recently I restored the transmission. Worked fine about of 200 miles, but yesterday the morning I had problems with 727. Suddenly, the tranny started slips. In park, neutral, drive or low, still moving forward, but in reverse the tranny brake. Accelerating fairly moves with difficulty to reverse.
Today I have disassemble and find the rear clutch discs fully burned and "bended". Everything else seems ok.
The question is: may what have caused this? Valve body problem ?
I will replace the clutch discs, but I would like to know what may have caused this. Has someone an idea where to look for a possible assembly fault?
Thanks

The bellville spring (first picture )(16-425-5 in exploded view)is in backwards/upside down! And obviously the seal is pooched.
when installing the piston , use a twisting /turning motion to get it in smoothly(with lots of lube)!
