6T70 Pump 2013, used and ready to install. Fits the 6T70. Ships fast from the USA.
2013 is the year the 6T70 changed underneath. GM began phasing in its Generation 2 hardware that year and made it standard from 2014, which means a 2013 Equinox, Terrain, Traverse, Acadia, Malibu or Impala can have either generation inside. If yours is slow into gear, slipping in every range or whining with engine RPM and a pressure test points at the pump, this is a used 2013 6T70 fluid pump assembly, a budget-friendly way to replace a worn pump with a complete factory unit instead of rebuilding a non-serviceable one.
The 6T70 pump sits beside the input shaft rather than behind it, driven by a sprocket set and a drive link. It feeds line pressure through an outlet seal to the valve body, which then splits it to the clutches, the converter clutch, the cooler and the lube circuit. On a clutch-to-clutch unit with no bands, there is no mechanical backup: if the pump cannot keep up, every shift suffers at once. A Gen 2 unit also runs thinner frictions in its 1-2-3-4 clutch, so it has little tolerance for pressure loss.
On a 2013 especially, rule out the look-alike first. Transmission Digest traced a slip-and-delay-in-first complaint on a 6T75 to a Gen 1 1-2-3-4 apply piston installed in a Gen 2 transmission; the Gen 2 piston fingers are 0.785 in. tall against 0.638 in. for Gen 1. If the unit has been apart before, that mix-up is worth checking. Then run the gauge test in Park or Neutral under 1500 RPM with the line pressure solenoid stepped through its range. The 6T70 pump failure symptoms guide has the full procedure, and the 6T70 Equinox common problems guide covers the faults that hit these 2013-era crossovers.
This pump is listed for the 2013 6T70. Because 2013 straddles the generation change, match it to your old pump before you install it and check the transmission build information, or send us your year and VIN and we will confirm it. It is a used part, not a remanufactured one; if you would rather have a remanufactured assembly, see the remanufactured 6T70 pump. If your unit is a 6T75 by RPO code, use the 6T75 version instead. All 6T70 parts are on the 6T70 collection page.
Rebuilding the rest of the unit at the same time? Pair it with the 6T70 overhaul kit for 2013-2020, and if shift quality is still off after the pressure is right, the 6T70 valve body is the next suspect.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Not guaranteed. 2013 was the start of GM's Generation 2 update, so compare the pump against yours or send us your year and VIN before ordering.
It is a used factory pump assembly. A remanufactured 6T70 pump is listed separately if you prefer that.
Yes. A Gen 1 1-2-3-4 apply piston in a Gen 2 unit leaves too much clearance and causes delay and slip in first, much like weak pump pressure. Check it on any unit that has been rebuilt before.
A new filter and neck seal, the pump outlet seal and the pan gasket. On a rebuild, an overhaul kit covers the remaining seals.
DEXRON-VI. Check the level with the engine running at operating temperature, then clear adaptives and road test.
