6T30 Low-speed Reverse Gear One-way Clutch Hub
As an automatic transmission expert, I'll analyze the most common failure modes of the 6T30 Low/Reverse One-Way Clutch (OWC) Hub:
Top Failure Modes of the 6T30 Low/Reverse OWC Hub:
-
Wear/Galling on Inner Race Contact Surface
-
The hub's inner race (where the rollers/sprags engage) often develops excessive wear or scoring due to:
-
Contaminated ATF (lack of maintenance)
-
Hard engagement shocks (aggressive driving)
-
Poor lubrication (clogged passages)
-
-
-
Roller/Sprag Bore Damage
-
The hub's bore (holding rollers/sprags) can become ovalized or develop grooves, preventing proper OWC locking.
-
Causes: Overloading, misalignment, or poor heat treatment.
-
-
Retainer Spring Fatigue/Fracture
-
The spring that maintains roller/sprag tension weakens or breaks, causing:
-
Intermittent engagement (delayed reverse)
-
Complete failure (no low/reverse)
