6T75 Pump 2007, used and ready to install. Fits the 6T75. Ships fast from the USA.
The 2007 model year is where the 6T70/6T75 family began, so any 2007 6T75 still on the road has close to two decades and usually well over 150,000 miles behind it. When one of these early units turns sluggish into gear, slips once it is warm, or develops a whine that tracks engine speed, a tired fluid pump is a strong suspect. This is a used 2007 GM 6T75 fluid pump assembly from the first-generation design, a direct way to put a complete factory pump back into an early unit at a used-part price.
On these transaxles the pump lives beside the input shaft instead of directly behind the torque converter. A drive sprocket on the input side, a driven sprocket on the pump and a drive link connecting them spin it whenever the engine runs. The oil it makes leaves through an outlet seal into the case, where the valve body regulates it into line pressure for the six-speed's clutch packs, the converter clutch, the cooler and the lube passages. In a first-generation 6T75, the pump, the sprockets and the drive link all carry the same mileage as the rest of the unit, so wear in any of them cuts the volume every clutch depends on.
Early 6T70/6T75 units have a well-documented weak point that has nothing to do with the pump. GM bulletin 09-07-30-012F covers 2007-2009 vehicles that lose Reverse, 3rd and 5th and set P0776 because the 3-5-R wave plate breaks. GM later extended coverage on that wave plate to 10 years or 120,000 miles, which means any 2007 is now outside it. If your complaint is that specific trio of gears, start there, not with the pump. Our Acadia common problems guide covers the bulletin and the updated parts.
Check the fluid level and condition hot, then scan for codes. A pump problem affects every range at once. Next, hook a gauge to the line pressure test port and step the line pressure solenoid through its range with a scan tool in Park or Neutral, keeping engine speed below 1500 RPM. If readings sit under GM's chart through the whole sweep, inspect the pump bolts, pump outlet seal, filter and filter neck seal before condemning the pump itself. The pump failure symptoms guide lays out the full test and what each result means.
This pump is listed for the 2007 6T75. Make sure the transmission is a 6T75 and not a 6T70 by reading the RPO codes on the Service Parts Identification label, since the same vehicles came with either unit. Keep it to first-generation units; GM's Generation 2 parts started showing up in 2013, and early and late hardware should not be mixed. Lay the old pump next to this one and compare the casting and bolt pattern, or send us your year and VIN and we will confirm. A 2013 6T75 pump is listed for later units, and the full parts range is on the 6T70/6T75 collection page.
If the pressure is right but shifts are still rough, a 2007 6T75 valve body is the logical next step for this early unit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It should not be assumed. GM introduced Generation 2 hardware starting in 2013, so this early pump is meant for first-generation units. Compare it to your old pump or send us your year and VIN.
Probably not. That pattern, often with P0776, is the 3-5-R wave plate failure described in GM bulletin 09-07-30-012F for 2007-2009 units.
No. GM's wave plate special coverage ran 10 years or 120,000 miles, so a 2007 vehicle is past the time limit.
The filter, filter neck seal, pump outlet seal and pan gasket at minimum. On a high-mile unit, also inspect the drive link and sprocket thrust washers.
DEXRON-VI only. Check the level at operating temperature, then clear adaptive values with a scan tool and road test.
