OE bushings in GM 6L80 and 6L90 transmissions have a tendency to wear out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, harsh shifts, burnt clutches and gear ratio or solenoid codes. Sonnax bushing kit 104030A-01K restores worry-free operation.

Upgraded material composition outperforms OE bushings
Superior wear characteristics eliminate premature deterioration
