Product Description

        • Typical Faults:

          1. Crescent Wear

            • Symptom: Low line pressure (P0756/P0776 codes, delayed shifts)

            • Cause: Abrasives score pump face (especially after torque converter failure)

          2. Drive Gear Spline Stripping

            • Symptom: No movement in any gear (metal debris in pan)

            • Cause: Torque converter hub wear transfers to pump

          3. 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.
