6T70 Shift Kit 2013, new and ready to install. Fits the 6T70. Ships fast from the USA.
The 2013 model year is where buying a 6T70 valve body part gets tricky. GM began switching the 6T70 to its second-generation controls, and that year a Malibu, Equinox, Impala or Traverse can have either version. This listing is the TransGo SK 6T70-G2, the kit for the Gen 2 valve body with no pressure switches. Owners usually find it while chasing a converter clutch that hunts at cruise, a flare or slip into 3rd or 5th, or a TCC or pressure control code on a 2013 or later unit.
A Gen 2 valve body works on the same principle as the earlier one. The pressure regulator valve sets line pressure, the actuator feed limit (AFL) valve sets the feed that the TEHCM solenoids work from, and the TCC regulator valve meters converter clutch apply. Gen 2 hardware changed around those valves. The pressure switches are gone, the rear body casting has a new exhaust, and the separator plates do not interchange with Gen 1. The kit includes a hardened PR valve with an internal balance passage and a spring, an oversize hardened AFL valve, a TCC regulator valve with a scarf-cut ring and extended lands, and a relief bushing, ball and spring that replace the factory isolator valve so line pressure spikes cannot break parts.
Read the codes and rule out electrical solenoid faults, misfires and a failing converter before you blame the valve body. Our Malibu 6T70 shift problems guide and Equinox shift problems guide cover the 2013-up symptom patterns and the GM bulletins behind them. Then confirm you have a Gen 2 unit, because this kit will not fit Gen 1.
TransGo rates this kit for 2013-and-newer Gen 2 6T70, 6T75 and 6T80 units without pressure switches. Because 2013 was a split year, check the RPO list in the glove box. MHM, M7U, M7V, M7W or M7X means Gen 2 and this kit fits. MH2 or MH4 means Gen 1. TransGo also warns that some fleet units built as late as 2016 are still Gen 1. With the valve body apart, a Gen 2 TEHCM has no pressure switches, and the original PR valve inner land measures about .303 in. A .314 in. land means a Gen 1 body. For Gen 1 units, use the 6T70 shift kit for 2007-2012. If you are unsure, send us your year and VIN. More parts are in the 6T70/6T75 collection.
Gen 2 AFL bores wear in a way a drop-in sleeve cannot fix, so TransGo requires its AFL-G2-TK reamer kit (6T70 Gen 2 uses the no-groove guide) to open the bore for the oversize valve. Ream at low drill speed with plenty of WD-40. Freeze the TCC valve with its sizing O-ring for 15 minutes and slide it in cold. Never force it, and do not pull it back out. TransGo recommends new bonded-gasket separator plates to stop cross-leaks, and says to inspect the six pulse damper bores. Refill with Dexron VI and run a fast learn. A worn or debris-damaged body may be better replaced outright. The 6T70 valve body is an option, and the 2013-2020 overhaul kit covers a full rebuild.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Check the RPO codes on the glove box label. MHM, M7U, M7V, M7W or M7X means Gen 2 and this kit fits. MH2 or MH4 means Gen 1 and it does not fit; you need the Gen 1 kit instead.
Yes. TransGo requires its AFL-G2-TK reamer tool kit to repair the Gen 2 actuator feed limit bore for the oversize AFL valve. You also need a freezer for sizing the TCC valve ring and a scan tool for the relearn.
It can help when the cause is TCC or pressure regulation wear. GM's bulletin for the 2014-2017 Equinox shudder points at valve body debris, so clean the valve body thoroughly and rule out misfires and converter problems before you install the kit.
Yes. TransGo lists the SK 6T70-G2 for Gen 2 6T70, 6T75 and 6T80 units. The 6T75 version of this listing is the same kit.
Dexron VI ATF. Refill to the correct level hot, then clear adapts and run the transmission fast learn.
