BTW, I never did post up what I found on tearing down the trans. It had the Alto 9 thin frictions with 8 thin steels and they were smoked. The were so coned that the pack became a big wave washer. There was no 3-4 rev kit and one of the springs was broken. There was also a check ball for the 2nd clutch that had beaten up the case and may have stuck, which could have also caused the 3-4 burn up. I really think though that the major culprit was no rev kit and the high rev shifts. The Transgo spring kit along with the 4L65E release springs should help this. Plus, the Smart Tech housing will allow me to run thicker frictions and steels and higher apply pressure.
