What it does

Variable displacement pump that supplies hydraulic pressure to the entire 6L80 valve body.

Fitment

2006-2017 GM trucks and SUVs with 6L80 or 6L90.

Common failure symptoms

Low line pressure across all gears, slipping, transmission overheating, premature clutch wear

Electrical specs

Replace with OE or quality reman during any major rebuild — failed pumps cause cascading damage.

Run a resistance check before condemning the solenoid. Bad wiring, corroded harness pins, or a failing PCM driver can cause identical symptoms.

  2. Remove torque converter
  3. Remove pump retaining bolts (front of transmission)
  4. Pull pump assembly straight forward
  5. Replace pump bushing and seal with new unit
  6. Lubricate new pump with assembly lube
  7. Torque pump bolts to 18 ft-lbs in cross pattern
  8. Verify pump turns smoothly by hand before reinstalling converter
