Cause:
OE bushing material composition allows premature wear.
Correction:
Install improved Sonnax sun gear shaft bushings to restore critical clearances and resist untimely wear.
Warning:
Caution: Use of an arbor press is required for correct installation. Do not use a hydraulic press or a bushing driver/hammer combination to install, as doing so will distort the bushing and cause fitment issues.
The OE sun gear shaft bushings located at front and rear of the sun gear shaft in ZF6HP26 and ZF6HP28 units have a tendency to wear out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, pressure control codes, and burnt B clutches. This Sonnax sun gear shaft bushing features superior wear characteristics, eliminating premature deterioration for worry-free operation. The Sonnax bushing's upgraded material composition outperforms the OE bushing.
Fits units with .991" (25.17mm) shafts only.
