6T70 Pump, remanufactured and ready to install. Fits the 6T70. Ships fast from the USA.
A 6T70 that hesitates before it grabs Drive, slips in every gear once it is warm, or whines with engine speed is often blamed on the valve body or a solenoid first. When a gauge on the line pressure port reads low across the board, the fluid pump is the part that is actually short. This listing is a remanufactured 6T70 fluid pump assembly for the GM six-speed front-drive transaxle found in 2007-2019 Chevrolet Traverse, Equinox, Malibu and Impala, GMC Acadia and Terrain, Buick Enclave and LaCrosse, and Cadillac SRX applications. It is sold as a complete assembly, so you are not reusing worn sprockets or a cover held on by stripped screws.
The 6T70 does not use a gear pump bolted directly behind the converter the way a rear-drive 4L60E does. GM lists it as the Fluid Pump Assembly, mounted off the input shaft centerline and turned through a drive sprocket, a driven sprocket and a drive link that works like a short chain. Everything in the transmission runs on what that pump delivers: the clutch-to-clutch shifts, the converter clutch apply, the cooler flow and the lube oil to the planetary sets. The pump output leaves through a fluid outlet seal into the case and draws through a filter with its own neck seal, so the pump is only as good as the seals around it.
Check fluid level with DEXRON-VI at temperature and scan for codes first. A broken 3-5-R wave plate (the classic P0776, no Reverse, 3rd or 5th) and valve body or TEHCM faults are far more common 6T70 failures and can feel like a pressure problem. Then run GM's line pressure check: gauge in the test port, scan tool commanding the line pressure solenoid in roughly 200 kPa steps, Park or Neutral only, under 1500 RPM. Low readings through the whole sweep send you to the pump, its bolts, its outlet seal and the filter. Our 6T70 pump failure symptoms guide walks the test step by step, and 6T70 common problems and fixes covers the failures that mimic it.
This pump is listed for the 6T70 with no single model year in the title. The 6T70 ran from 2007 through 2019 with a control and hard-part update around 2013, and the pump drive and filter details are not guaranteed to interchange across every revision. Compare your old pump side by side before installing, or send us the year and VIN and we will confirm it. If you know your exact year, we also stock the 6T70 pump for 2007 and the 6T70 pump for 2013. Everything else for this unit is on the 6T70 parts page.
Doing a full refresh at the same time? The 6T70 overhaul kit for 2013-2019 puts new seals and gaskets in with the pump.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the 6T70 used from 2007 to 2019 in front-drive GM crossovers and sedans. Pump details changed with the 2013 update, so match it against your old pump or send us your year and VIN before you order.
Put a gauge on the line pressure port and command the line pressure solenoid through its range with a scan tool. Low pressure in every step points to the pump and its seals; correct pressure with a bad shift points to the valve body, a solenoid or a clutch.
The filter and its neck seal, the pump outlet seal and the pan gasket at minimum. If the unit is coming apart anyway, an overhaul kit covers the rest of the seals.
DEXRON-VI only. GM lists 7.0 to 9.0 liters for an overhaul refill; check the level hot with the engine running.
Yes. Clear the transmission adaptive values with a scan tool and complete a road test so the TCM relearns clutch fill and shift pressures.
