Chrysler 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions commonly exhibit wear in the low/reverse bore. This issue stems from the valve getting side-loaded due to the length of the valve being dimensionally close to its diameter. As wear progresses, hydraulic fluid cross leaks to other circuits and results in the loss of apply pressure to the low/reverse clutch. Consequences of this pressure loss lead to burnt low/reverse clutch, delayed/no Reverse, and no engine breaking when in Low.

Installing Sonnax low/reverse switch checkball sleeve kit 92835-41K restores hydraulic integrity to re-establish normal shift operation and prevents premature wear.

• Steel sleeve allows checkball to operate in unworn bore
• Improved design combats premature wear
• Drop-in Zip Valve™ parts install quickly and easily
