RETAINING RING DIRECT DRUM SHAFT AOD
# 42648

Direct Drum Shaft Retaining Ring

RETAINING RING DIRECT DRUM SHAFT AOD

Symptoms:

  • Restricted lube flow

Cause:
Spline wear causes the direct drum shaft to contact the output shaft and shut off lube flow.

Correction:
Sonnax retaining ring fit prevents the direct drum shaft from moving backward and contacting the output shaft and shutting off lube flow.


In vehicles with a Ford AOD transmission, the direct drum splines can wear, causing the direct drumshaft to contact the output shaft and shut off lube flow. The late shaft design allows this Sonnax retaining ring to fit into the OE groove. The early shaft design requires a groove to be machined to accept the retaining ring. The shaft has been depth hardened sufficiently from OE to ensure strength after machining.

  • Prevents lube flow shut-off
  • Salvages drums with worn splines

Note:
Late-model shaft requires no modifications. Early-style shafts will require machining a ring groove.
