Cause:Premature wear due to sub-optimal OE bushing material in ZF 8-speed units allows fluid loss and misalignment that results in harsh shifting and clutch failure.
The Sonnax parts restore hydraulic integrity and provide a positive seal with the pump bore. The Sonnax boost valve kit restores hydraulic integrity and provides a positive seal with the pump bore.
OE bushings in Chrysler 845RE and listed ZF 8-speed units 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. The Sonnax improved bushing kit restores worry-free operation.
- Upgraded material composition outperforms OE bushings
- Superior wear characteristics eliminate premature deterioration
