Of course! I would love to share knowledge. It also helps others that want to crack open the case to fix their trannies. I also started rebuilding my own 904s and 727s 20 years ago when a tranny (aamco) tried to Charge me $1200, in 1984 to put a seal in. (high clutch piston seal). The problem: I didn't have 3rd gear, or reverse. I got a trans kit, pulled it apart, changed all of the burnt clutches, put it back in, SAME PROBLEM. Looked in a service manual and noticed that the piston seals needed a special tool. Took it up to AAMCO, asked for a price to just change the piston seal. Same price as a rebuild, $1200. I took it home and made my own tool to compress those springs, then fixed it myself. Since then, I've always rebuilt all of my trannies for my race cars.
