A very long story short I think I have a transmission with clutch packs that are failing due to low fluid condition while at the track. GM is doing everything they can to ignore the clutch packs and try to fix something else. I'm working with them because to my knowledge, nobody makes an aftermarket 10L90 and just replacing with stock is the best We can do.

In looking around I saw these
Raybestos #RGPZ-269 GM 10L90 GPZ Clutch / Friction Module 2018-On. Upgrades Available Here


Does anyone know if this is just an improvement going in the newer 10L90? Or it's an aftermarket upgrade? I have one of the very first 10L90 delivered, so some improvements wouldn't surprise me but I hadn't heard of any yet.

Have you considered targeting one of the new A10 1LE transmissions? It has a different pan setup supposedly to address the very track cooling issues that were a possibility with the A10.

I didn't know about this, that would definitely be something I'd be interested in getting. I wasn't having a cooling issue, but I'm interested in any improvements.
