Description
Part #: RFE-7B-HP
Until now, when someone increased the power output of the engine, the only way to significantly increase the transmission operating pressure required reprogramming the computer. As a result, computer programming often leads to harsh or binding shifts, erratic operation and at times catastrophic internal hard parts failure.
