Product Description

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.
