All the parts in the fail are not bad, but you can see which ones are. This is after 5 hours of driving. No hard pulls or stop and go, all interstate.
The Fail..

Snap Ring Not Fully Seated in Reverse Input Drum

Snap Ring is the Stop for the Reverse Reaction Drum/Shell.
3/4 Clutchs Burnt
Top Pressure Plate for 3/4 Clutch Pack got Extremely Hot
Scarf Cut Input Shaft Rings Instead of Solid Ones
Reverse Input Drum was Stack with way to Much Clearance
4-Pinion Front Planet

I did not see a collar over the splines of the input drum or new piston.There is no way that trans will hold 700 hp without that mod.A stock drum is good to maybe 450 hp max.Just my opinion.

Yeah aamco, it was just a normal rebuild... for the 3rd time, could never give me a straight answer why it kept screwing up, so I said FU. Trans would fail less than 24 hours after R&R. I got bad pump, clutches, wiring harness all for excuses multiple times. Turns out just shitty workmanship with crappy tolerances and parts. The above happened after 5 hours of highway driving.
It was well priced. Out of repect for the builder I will not disclose price.
