6T40 automatic transmission oil pump assembly hub stator
Top Failure Modes:
-
Stator Shaft Galling/Scoring – Poor lubrication or debris causes wear on the stator support hub, leading to pressure loss.
-
Bushing Wear – The pump bushing wears, causing rotor misalignment and low line pressure.
-
Seal Ring Groove Damage – Worn grooves allow internal leaks, reducing pump efficiency.
-
Cracking Near Drive Lugs – Fatigue fractures from high torque loads (common in 6T40s).
-
Stator Shaft Spline Wear – Slippage or stripping due to excessive torque or misalignment.
Key Symptoms:
-
Low line pressure (delayed shifts, slippage)
-
Whining noise (pump cavitation)
-
Metal debris in fluid (bushing/seal failure)
Fix: Replace the pump assembly (including bushings/seals) and flush the system.
