Typical Faults:
Crescent Wear
Symptom: Low line pressure (P0756/P0776 codes, delayed shifts)
Cause: Abrasives score pump face (especially after torque converter failure)
Drive Gear Spline Stripping
Symptom: No movement in any gear (metal debris in pan)
Cause: Torque converter hub wear transfers to pump
Pressure Regulator Sticking
Symptom: Erratic shifts or harsh engagements
Trigger: Varnish buildup from degraded Dexron III
Critical Measurements:
Rotor Clearance: >0.15mm requires replacement
Prime Test: Should hold 50+ psi for 10+ seconds
Pro Tip: Always replace pump and TC together – 85% of pump failures originate from converter debris.
