The OE bushings located at front and rear of the sun gear shaft in ZF6HP19 and ZF6HP21 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. Sonnax sun gear shaft bushing 95030-06D features superior wear characteristics, eliminating premature deterioration for worry-free operation. The Sonnax bushing's upgraded material composition outperforms the OE bushing.
