6T75 Pump 2013, used and ready to install. Fits the 6T75. Ships fast from the USA.
A 2013 6T75 that hesitates before it grabs Drive, slips on a hill with a full load of passengers, or howls in step with the tachometer is usually short on line pressure, and the fluid pump is where that pressure starts. This listing is a used 2013 GM 6T75 fluid pump assembly, pulled as a complete unit with its housing and cover together, so you replace the pump outright rather than trying to repair one GM never meant to be opened.
The 6T75 is the heavier-duty version of the 6T70 family, picked for applications that carry more weight or tow. Its pump does not sit behind the converter like a rear-drive unit. It is mounted off to the side and turned by a sprocket on the input side, a second sprocket on the pump and a drive link between them. Oil leaves the pump through an outlet seal into the case, and from there the valve body meters it to the clutches, the converter clutch, the cooler and lubrication. With no bands and no one-way backup for most ranges, every gear in this clutch-to-clutch transaxle leans on that one pressure source. Under the bigger torque loads a 6T75 sees, even a small loss of volume shows up as slip.
Pump trouble hits all ranges at once. If the complaint is limited to one shift or a specific gear, look elsewhere first. Put a gauge on the line pressure port, command the line pressure solenoid through its range with a scan tool in Park or Neutral below 1500 RPM, and compare against GM's chart. Low readings throughout point to the pump circuit, but GM's own check order still starts with cheaper items: loose pump bolts, a leaking pump outlet seal, a torn filter neck seal or a filter that is not seated, then the line pressure blow-off valve. Our 6T70/6T75 pump failure guide walks through the full test. For three-row crossovers, the Acadia shift problems guide helps separate a pressure fault from a valve body or solenoid fault.
This pump is listed for the 2013 6T75. Two things to check before you order. First, make sure your transmission really is a 6T75 and not a 6T70; the same crossover nameplates were built with both, and the RPO code on the Service Parts Identification label settles it. Second, 2013 is the model year GM started bringing in its Generation 2 internals, so a 2013 unit can be built either way. Set your old pump beside this one and compare castings and mounting points, or send us your year and VIN and we will check it. If you prefer a remanufactured assembly or yours is an earlier unit, see the remanufactured 6T75 pump. Everything else for this family is on the 6T70/6T75 collection.
If the case is coming apart anyway, the 6T75 banner rebuild kit covers the seals and frictions, and if pressure tests good but shifts stay harsh, the 2013 6T75 valve body is the next part to look at.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Check the RPO codes on the Service Parts Identification label, usually in the glovebox or center console. Model name alone is not enough because GM built the same vehicles with both units.
Not automatically. 2013 is when GM began its Generation 2 changes, so compare it against your old pump or send us your year and VIN before buying.
It is a used GM pump assembly. A remanufactured 6T75 pump is listed separately.
Usually not. Losing that group of gears, often with P0776, points to the 3-5-R clutch and its wave plate. A failing pump affects every gear together.
DEXRON-VI, with the level checked at operating temperature. Clear the transmission adaptive values with a scan tool and road test so the TCM relearns shift timing.
