6T75 Pump, remanufactured and ready to install. Fits the 6T75. Ships fast from the USA.
The 6T75 is the higher-capacity member of GM's 6T70 family, and it tends to live a harder life: three-row crossovers like the Traverse, Acadia and Enclave, often loaded with people or pulling a trailer. When one of these starts lagging into gear, slipping when hot or growling with engine speed, the fluid pump is one of the first things a gauge will clear or condemn. This listing is a remanufactured 6T75 fluid pump assembly, rebuilt as a complete unit with the sprocket drive, so it goes in ready to make pressure.
Like the rest of the 6T70/6T75 line, the 6T75 pump is offset from the input shaft. A drive sprocket on the input side turns a driven sprocket on the pump through a drive link, and the pump feeds line pressure into the case through an outlet seal. Every clutch apply, converter clutch apply and the cooler and lube circuits depend on that output. Because the 6T75 is chosen for heavier duty, its clutches need full clamping pressure under load, so a pump that is only slightly short shows up first on a grade or with a trailer behind it.
Start with fluid level, fluid condition and codes. A 6T75 with a cracked 3-5-R wave plate sets P0776 and loses Reverse, 3rd and 5th, and that is a clutch problem, not a pump problem. Next, run the line pressure check with a gauge in the test port while the scan tool steps the line pressure solenoid in Park or Neutral under 1500 RPM. If the readings stay low, work GM's list in order: pump bolts, pump outlet seal, filter and filter seal, then the line pressure blow-off valve. One trap on 2013 and later rebuilds: Transmission Digest documented a 2015 Equinox 6T75 where a Gen 1 1-2-3-4 apply piston in a Gen 2 unit felt exactly like weak pump pressure. Our 6T70/6T75 pump failure guide covers both, and the Acadia common problems article lists the bulletins that apply to these crossovers.
This pump is listed for the 6T75 without a model year. Do not go by the vehicle name alone; the same models were built with either a 6T70 or a 6T75, so read the RPO code on the Service Parts Identification label in the glovebox or console to confirm which unit you have. GM also updated the family around 2013, so compare the old pump to this one or send us your year and VIN. Year-specific versions are the 6T75 pump for 2007 and the 6T75 pump for 2013, and the rest of the parts are on the 6T70/6T75 parts page.
If the pressure test points past the pump, the 6T75 valve body for 2008-2012 is the next part in the circuit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Read the RPO code on the Service Parts Identification label, usually in the glovebox or center console. The same crossover models were built with either unit, so the label is the reliable answer.
They share the same sprocket-driven pump layout, but we list them separately by unit. Match the pump to your transmission and compare it to your old part, or send us your year and VIN.
Probably not. That pattern with P0776 is the well-known 3-5-R wave plate failure. A weak pump hurts every range at once.
A new filter and neck seal, the pump outlet seal and a pan gasket. On a full rebuild, add a master rebuild kit and new sealing rings.
DEXRON-VI only, level checked hot. Clear adaptive values with a scan tool afterward and road test so the TCM relearns.
