Product Description
Fits: 48RE
Chrysler 48RE units often have problems with Reverse operation such as delayed engagement and soft or slipping Reverse. Other concerns may be poor cooler charge at idle and poor line pressure control. These problems can be traced to excess wear at the internal diameter of the line pressure sleeve, which allows pressure loss that hinders line rise. Eliminate sleeve wear and revive line pressure operation by installing Sonnax line pressure plug and sleeve kit 22771A-19K.
- Hardcoat anodized aluminum valve combats premature wear
- O-Ringed sleeve provides optimal circuit seal to help restore line rise
Notes
If excess PR bore wear is discovered, Sonnax offers oversized lube regulated pressure regulator valve and line/TV pressure plug kit 22771A-16K.
