The EPC solenoid (force motor) has a preset of about 170-180 psi of main line pressure at WOT in the "D" position. When using the Trans-Go modulator, and the Trans-Go main boost valve, and you install the modulator pin "as is" (no grinding), it will put out about 220-235 psi at WOT in the "D" position. This can give you a much longer 3-4 clutch life. It also allows for a much faster downshift than its computer controlled couterpart.
