Symptoms:
- OD roller clutch failure
- Aftermarket replacement bushings are a poor fit in output shaft housing
Cause:
Output shaft housing bore varies in diameter, resulting in inconsistent bushing fit.Correction:
Machine the output shaft bushing housing I.D. and install Sonnax oversized overdrive sprag pilot precision bushing.42RE, 42RH, 44RE, 44RH, 46RE, 46RH, 47RE

View Instructions Find a DistributorThe sprag pilot bushing bore found in '88-later listed Chrysler units' overdrive output shafts can vary in diameter by .011". This variation may result in loose-fitting replacement bushings. You can restore overrunning clutch and output shaft operational clearances by machining the output shaft and installing Sonnax oversized overdrive sprag pilot bushing 12509-01.
