- - - 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.
