BUSH IN/OUTPUT SHAFT 6HP19/26/6R80
# 99420-01

BUSH IN/OUTPUT SHAFT 6HP19/26/6R80

Both Input and Output Shafts

Fits units with .669" (16.98mm) dia. shaft journals only.

Symptoms:

  • Bushing wear
  • Bushing failure
  • Ratio codes
  • B Clutch burned

Cause:
OE bushing material composition allows premature wear.

Correction:
Install improved Sonnax input/output 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 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. This Sonnax input/output shaft bushing features superior wear characteristics, eliminating premature deterioration for worry-free operation. The upgraded material composition outperforms the OE bushing.
