I read it the same way, if your oil has risen above 113 temp and rpm's are above 1350, the pressure should be 160 psi regardless of brake engagement. I don't see it stated there, are these tests done in neutral or in gear?
I put a new solenoid spool on it and it seems to have fixed it. Its kicking down to 150psi at above 1300rpm. Hopefully that solved the heating issue, but I need to run it a while to know.
i believe i solved mine, had a couple of broken wires on engine speed sensor and tc output speed sensor. i believe the priority valve wasnt getting information from the ECM to function.Same problem here. 5LN serial d6r
