6T70 Pump 2007, used and ready to install. Fits the 6T70. Ships fast from the USA.
If your 2007 6T70 has started to moan with the engine, takes its time going into gear, or now sits in Drive with the engine revving and barely creeps, the problem may be the part that feeds everything else: the fluid pump. This is a used 2007 GM 6T70 fluid pump assembly for the first production year of the six-speed front-drive transaxle. It arrives as a complete housing-and-cover assembly, the way GM supplies the part, so there is nothing to rebuild on the bench before it goes in.
GM packaged this transaxle tightly, so the pump is not stacked behind the converter. It sits off the input shaft centerline and is chain-driven through a drive sprocket, a driven sprocket and a short drive link. The pump pulls oil through the filter, then sends it through an outlet seal to the valve body, which builds line pressure for six clutch-to-clutch shifts, applies the converter clutch and feeds the cooler. Because pump output depends on that sprocket drive, the noise and wear problems on a first-year unit often start in the link and thrust washers as much as in the pump body itself.
GM's own noise chart for this family lists several pump-area causes worth knowing before you spend money: a loose or worn drive link, worn thrust washers on the drive and driven sprockets, a damaged pump shaft spline, and leaking seals at the pump outlet, filter or transfer drive gear support. A noise that changes with road speed and not engine speed usually lives in the final drive or differential instead. Check the fluid first; aerated or low fluid makes a healthy pump whine too. Then confirm with a pressure gauge on the line pressure port while the scan tool steps the line pressure solenoid, in Park or Neutral below 1500 RPM. Our 6T70 pump failure guide explains how to read the result, and the 6T70 common problems guide covers the faults that mimic a weak pump, including the 3-5-R wave plate failure that hit 2007-2009 units.
This pump is listed for the 2007 6T70, a first-generation unit. Confirm by RPO code that your transmission is a 6T70 rather than a 6T75, because GM used both in the same vehicle lines. Stay within first-generation hardware; GM started phasing in Generation 2 parts in 2013, and early and late pieces are not meant to be mixed. Compare your old pump to the photos, or give us your year and VIN and we will check. For later units, see the 2013 6T70 pump, or choose the remanufactured 6T70 pump. All parts for this transmission are on the 6T70 collection page.
Rebuilding the unit while it is apart? The 6T70 clutch module for 2007-2012 is a common companion part on early transmissions.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
GM lists a worn drive link, worn sprocket thrust washers, damaged pump shaft splines and leaking pump or filter seals as causes. Check fluid level first, then line pressure.
Do not assume it will. This is a first-generation pump, and GM began phasing in Generation 2 parts in 2013. Send us your year and VIN to confirm.
This listing is for the 6T70. Check your RPO code; if it shows a 6T75, use the 2007 6T75 pump listing instead.
It is a used GM assembly. A remanufactured 6T70 pump is also listed if you prefer one.
Refill with DEXRON-VI, check the level at operating temperature, clear adaptives with a scan tool and road test through every gear.
