2004 48 RE ATS Transmission line pressure test

What should the results be of a line pressure test at idle and also at WOT?

idle = 75 - 85 psi?

WOT = 110+ psi?

In addition, with ATS torque converter and co-pilot what should the line pressure test be? Higher? What are the test numbers?

WOT should be higher I would think, I know mine runs over 160-170 at WOT, your idle PSI looks fine. I could be wrong for your application, but tranny was built for a race application, and shifts very firm.

Goerend sets his tranny around 150-170 at WOT, stock is 85-95psi. I might be wrong but I think the co-pilot only controls TC lockup.
