The OE bushings used at the input-to-intermediate shaft and intermediate-to-output shaft in ZF6HP19, ZF6HP26, ZF6HP28 and Ford 6R80 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 loss of correct pressure to the B-clutch. Sonnax input/output shaft bushing 95030-05 features superior wear characteristics, eliminating premature deterioration for worry-free operation. The upgraded material composition outperforms the OE bushing.
