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.
