Sonnax highlights its heavy duty outer pump gear set for Chrysler 68RFE transmissions. The company says users can avoid wear in these transmissions’ pump gears by using this pump gear set (#72530B-04K).
This set includes two high-pressure gears with an anti-wear coating. Use this set in conjunction with Sonnax center pump gear #72530-02 to replace all three gears in the pump, the company recommends.
