Pentosin ATF1 is what I used in my stock transmission and it shifts smooth. I thought I read later it was compatible with older ZF transmission but not for ours. But I have had no issues with it in the past 20k.I don’t have PD transmission, is that ok with my regular transmission! I need oil change 85,000 !

What is the best ATF for my tranny OEM or aftermarket?
IIRC, The clutch material has different thermodynamic properties which makes it imperative to run the trans through an external cooler. I have attached the clutch material brochure that Jason provides.Is the external cooler needed just because of the new plates or is it recommended due to anticipated track/heavy use?
PD transmissions are just rebuilt 6hp21's with race bushings, these clutches, and ZF overhauled torque converter and valve body.Are these clutches a direct drop in to our common AT. Or only for PDtrans
