Service bulletin PIP5314

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This Preliminary Information communication provides information to the technician about vehicles that have several areas where leaks have been found from inside the torque converter housing. Technician should start with diagnose per Service Information document ID: 2414199 by adding dye. If the leak is coming from torque converter seal, replace torque converter seal and inspect torque converter hub for possible sharp edges on the transition from flats to hub diameter that may damage the seal when the torque converter is installed. If sharp edges are found, dress the edges or replace the torque converter. If the leak is from any of the outer converter housing bolts, replace Separator Plate, both separator plate gaskets, the pump O-ring, and all the retaining bolts and seals. Install new copper washers under the two lower housing bolts. If Leak is through the torque converter housing casting replace the casting, the gaskets and the separator plate.
