6T40 Valve Body 2013-2018, remanufactured and ready to install. Fits the 6T40. Ships fast from the USA.
A 2013-2018 Chevrolet Cruze, Malibu, Sonic, Buick Verano, Encore or similar GM front-driver with a 6T40 that flares on the upshift, loses 4th through 6th, bangs into gear, or keeps setting pressure control solenoid performance codes such as P0776, P0796, P2714 or P2723 very often has worn bores in the valve body rather than a dead solenoid. This remanufactured unit is built for the 2013-2018 window, after GM moved the family off the original Gen 1 controls, so you are replacing the hydraulic half of the control system with a tested assembly instead of chasing one leaking bore at a time.
The 6T40 has no stand-alone TCM under the dash. The TEHCM, the combined solenoid body and control module, bolts straight onto the valve body. Its five clutch pressure control solenoids only send a signal; the valve body turns that signal into apply pressure through a clutch regulator valve for each circuit (3-5-R, Low/Reverse and 4-5-6, 2-6, and 1-2-3-4). Upstream of all of them sit the pressure regulator valve, which sets line pressure, and the actuator feed limit (AFL) valve, which trims line pressure down to the feed oil every solenoid works from. When the AFL or regulator bores wear, every clutch circuit loses pressure at once, which is why one tired valve body can look like three separate failures on a scan tool.
Rule out the cheaper causes first. Check for a calibration update and reflash, set the fluid level hot at the check plug, and measure the solenoids: pressure control solenoids should read 3-5 ohms and the shift solenoid 16-20 ohms, and none of them should ever see 12 volts. A hard shift with P0776 alone can be the 3-5-R wave plate, not the valve body. If the solenoids test good and you still have several pressure complaints, vacuum testing the AFL, pressure regulator and TCC regulator bores is what proves it. Our 6T40 valve body symptoms and testing guide lays out that order step by step, and the shift solenoid guide helps separate a TEHCM fault from a hydraulic one.
This listing covers 6T40 transaxles built 2013-2018. GM switched most applications to Gen 2 controls in 2012, and later units that Sonnax groups as Gen 3 arrived partway through this window on some vehicles, so the year alone does not settle it. Gen 1 valve bodies do not interchange with Gen 2 or Gen 3 at all. Before you order, read the eighth digit under the TEHCM bar code (B, C or D means Gen 2), count the filter plate screens (three on Gen 2), and compare your casting and connector to the photos, or send us your year and VIN and we will confirm. If your car is a Gen 2 build and you only need the casting, the bare Gen 2 valve body casting is an option. If the RPO label shows MH7 or MHC, your car has the heavier-duty unit and needs the 6T45 valve body for 2013-2018 instead.
If the car tows or runs hot, adding an auxiliary 6T40 transmission cooler keeps fluid temperature, and bore wear, down on the new unit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built for 6T40 units from 2013-2018. Because GM ran Gen 2 and, on some later vehicles, Gen 3 controls in this window, confirm the TEHCM ID digit, filter plate and casting against the photos, or send your year and VIN before ordering.
The eighth digit under the TEHCM bar code is 1, 2 or 3 on Gen 1 and B, C or D on Gen 2. Gen 1 TEHCMs have pressure switches and a filter plate with many screens; Gen 2 has no pressure switches and three screens. Gen 1 parts do not interchange with Gen 2 or Gen 3.
Yes, if it is the correct generation, tests good (3-5 ohms on the pressure control solenoids, 16-20 ohms on the shift solenoid) and has the latest calibration. Replace the filter plate seals; they leak if reused.
Dexron VI only. With the engine idling and the car level, set it at the check plug with fluid temperature between 185 and 203 F. Overfill by as little as half a quart can push fluid out the vent and set P0218.
Yes. Run Service Fast Learn Adapts with a capable scan tool once the fluid is in the 185-203 F window. Expect a few odd shifts that clear within 10-15 upshift and downshift cycles.
That pattern is often a cracked 3-5-R wave plate or a 3-5-R snap ring problem rather than the valve body. Check that before replacing hydraulic parts.
