Hi,
Do any companies do a high pressure reg spring kit for the C4?
I want to raise my pressure from 165 to at least 225psi like I have been told many other have.
Thanks
Rod

Using two retainers help alot. Easiest way is go to a transshop and find a pressure reg. spring a hair smaller around and slide them inside each other. Little trick my ex uncle inlaw showed me. he build trannies of everykind for 45 years.

Update here on P.2, interesting a T400 forward clutch spring
