Order this TransGo TF-Boost Boost Valve Repair for your 1988-2007 Dodge/Chrysler A518/46RH/46RE/A618/47RH/47RE/48RE Transmission. The boost valve bore wears out in the area of the large land. The large land is the reaction area for the throttle pressure. The throttle pressure acts on the boost valve, which in turn acts on the pressure regulator valve to raise the main line pressure accordingly. This most common reason for the reverse band burn up. Adequate main line pressure rise is required to provide enough clamping force under all load conditions to prevent slipping, as well as to achieve proper shift quality. Consequently, a compromised boost valve will cause complaints of soft shifts and burnt frictions and TCC slip.
