OE Part No. 29506468View Instructions
OE center support bushings in listed Allison® AT units tend to wear out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, slipping/no Reverse, slipping/no 4th, and burnt 4th range clutches. Sonnax center support bushing S29506468 features superior wear characteristics, eliminating premature deterioration for trouble-free operation.
