Product Description
        • Typical Faults:

          1. Rotor/Gear Wear

            • Symptom: Low line pressure (P0841/P0868 codes, delayed shifts)

            • Cause: Contaminated ATF or metal debris scoring surfaces

          2. Seal Failure

            • Symptom: Pressure loss at idle (pump whine)

            • Trigger: Hardened/rolled seals from heat/age

          3. Cavitation Damage

            • Symptom: Foamy ATF, erratic shifts

            • Root Cause: Clogged filter or aerated fluid

          Critical Checks:

          • Clearance: Rotor-to-housing >0.15mm = replace

          • Prime Test: Should generate 20+ psi instantly at crank

          • Debris Inspection: Metal flakes indicate imminent failure

          Pro Tip: Always replace pump and torque converter simultaneously – 70% of pump failures originate from TC debris.
