Like clutch material? Amazingly this 727 would still chirp the tires on 1-2 shift as long as I kept tightening up the adjuster every couple weeks when I was daily driving my challenger with this in it. Until I ran out of adjuster threads. Swapped in a TCI Streetfighter years ago, just disassembling this old one for the usuable parts and scrap piles.

Metal-to-metal clutches are quite efficient given enough apply pressure...kinda like the Sure-Grip differential.

I believe the technical term is "smoked" - BTDT.

Last 904 I smoked was about 10 years ago, and dropping the pan in a 10,000SF shop, you could smell the muck from across the shop...

Been there, done that. The really fun one was when I dropped the pan, and everything had a nice thick coating of aluminum powder. I decided I needed to rebuild a different trans. I was told the torque converter probably came apart, but I wasn't up for the clean up task. 904s were not that hard to find. Gene

Wow - I thought you were showing us one of your wife's cake pans and you at the entire cake!

I thought this thread was going to be about those young men in white shirts and little ties that knock on your door to "witness" to you.
