Maybe in a car it would last. In a heavy truck, I have my doubts, unless modified further.

I recently installed a TVS1900 on a GMC 6.0 with the 4L70E. The transmission lasted less than 12 hours. Granted, the truck owner is hard on equipment, and was beating on it. But the truck is 100% stock besides the TVS, and is on the Maggie tune, with the stock 3.4 Maggie pulley. He has a FLT level 7 on order.

sound like a basic rebuild that most guys do to their 60e.
I didn't hear anything to special.
