A Billet Pump Rotor is absolutely necessary with Constant Pressure, The stock cast pump rotor is not designed for a 100% Duty Cycle.

The trans will shift hard under light throttle, This beats up the Splines & Hard Parts in general........It is really bad on Chain Style Transfer Cases!

The only good a Constant Pressure VB will do is allow you too adjust the TV Cable for Shift Timing.....Incorrect TV adjustment will not burn frictions with this VB.

Fine tuning a 700R4 to Upshift/Downshift exactly when you want makes Carb Tuning look easy.

Thank you for the quick reply and info. This thread is very informative and answered a lot of questions for me.
