6L80 Pump 2006-2018, new and ready to install. Fits the 6L80. Ships fast from the USA.
Read this first: this is not a complete pump assembly. It is the new internal rotating group for the 6L80 front pump, the parts that actually wear: the pump rotor, the pump slide, 13 vanes, the plastic vane guide, two vane guide rings and two pump rings. It is aimed at a rebuilder or a driveway mechanic who already has the transmission apart on a 2006-2018 Silverado, Sierra, Tahoe, Yukon, Escalade, Camaro SS or Corvette and has found a scored rotor, chipped vanes or a cracked slide, and would rather renew the guts than buy a whole pump.
The 6L80 uses a variable-displacement vane pump driven by the torque converter hub. The rotor spins inside the slide, and the vanes ride out against the slide's bore to trap and push fluid. Instead of dumping excess flow, the slide pivots against its spring to shrink or grow the pumping chamber, so output follows what the transmission actually needs. When the rotor face or slide bore gets scored, or a vane sticks or chips, the pump cannot build or hold line pressure, and every clutch in this clutch-to-clutch six-speed feels it at once.
Put a pressure gauge on the line tap before you pull anything. Low pressure in every range points toward the pump or the pressure regulator valve rather than a single clutch circuit. Our 6L80 pump failure symptoms guide lays out the bulletins and teardown checks, and the 6L80 common problems guide covers the clutch and valve body faults that can feel similar. Once the pump is out, look for scoring on the rotor pocket in the pump body and cover. If the pocket itself is badly scored, new internals will not seal against it and a full assembly such as the complete 6L80 pump is the better fix.
This kit uses the .708-inch-thick rotor and slide with the 13-vane design. It is listed for 6L45, 6L50, 6L80 and 6L90 units from 2006 on, including 2008-2014 Silverado and Sierra 1500, 2006-2014 Tahoe, Yukon and Escalade, 2009-2014 Camaro SS, 2006-2014 Corvette, 2006-2010 Hummer H2, 2008-2009 Pontiac G8 3.6L and the Holden Commodore. Pump parts changed with production date and with earlier replacement pumps, so do not order by vehicle alone: measure your old rotor and slide thickness and count the vanes before ordering, or send us the year, VIN and transmission tag. More versions are in the 6L80 transmission parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the internal rotor and slide kit: rotor, slide, 13 vanes, vane guide, vane guide rings and pump rings. You reuse your pump body and cover, so they must be free of deep scoring.
Measure the thickness of your old rotor and slide and count the vanes. This kit is the .708-inch, 13-vane design. Do not order by year and model alone, since replacement pumps and production changes can differ.
The kit is listed for 6L90 units, including 2007-2014 Silverado and Sierra 2500HD and 3500 with the 6.0L or 6.2L. Confirm the rotor thickness on your unit before ordering.
Replace the pump bushing, front seal and filter, and check the pump cover sealing rings. Inspect the converter hub for wear, since a scored hub will damage a new seal and bushing.
Dexron VI. Prime the new rotor, vanes and slide with Dexron VI during assembly so the pump picks up quickly on the first start.
Yes. GM has noted that a damaged 6L80 pump can send a pressure spike down the filter neck on a cold start and split the filter, so a cracked filter calls for a pump inspection, not just a new filter.
