What is the maximum pressure we can run on a 4L60E?? I know on my reverse manual 700, I run between 200 and 350 psi. Need to know so I can adjust my trans pressure tables accordingly. I have base tables at 90 psi max and there is an adder that adds between 20 and 40 psi additional on full throttle blasts.

Please help as I will be getting my car tomorrow evening and I want to reprogram my PCM before I leave.

Thanks,

Ryan
