6T45 Valve Body, remanufactured and ready to install. Fits the 6T45. Ships fast from the USA.
The 6T45 is the heavier-duty cousin of GM's 6T40, built into the Chevrolet Equinox, Malibu and Captiva and the GMC Terrain where the 2.4L four-cylinder needed more clamping capacity than the smaller-car 6T40 was built for, and on this platform the valve body is the usual cause of a harsh or flared 2-3 shift, slipping gears, or a transmission that drops into limp mode with a stored code. This is a remanufactured, bench-tested 6T45 valve body - every bore, check valve and solenoid connection is verified on a test stand before it ships, not sold as an unknown-history used pull.
The valve body is the hydraulic control center of the 6T45 - it routes line pressure through precision bores and spool valves to apply each clutch pack and band, and because this is an electronically controlled transaxle it also carries the shift and pressure-control solenoids the TCM fires to time every shift. Because the 6T45 handles more torque than the base 6T40, the same wear patterns in the valve body tend to show up as a sharper, more noticeable shift complaint on this application.
General Motors' own Preliminary Information PI0724B documents a harsh 2-3 shift on 2011 Equinox, Terrain and Captiva models with the 2.4L engine, traced to the TCM calibration working against this exact valve body - and ATRA's "6T40/45 Diagnosis and Fixes" writeup adds that pressure switch rivet failures were common on these units through 2012 production. Our 6T40/6T45 common problems guide covers both failure patterns in detail, and our shift solenoid symptoms guide helps separate a solenoid-only fault from the valve body itself before you spend money on the wrong part.
This listing is built for the 6T45 as installed in the 2.4L-equipped Chevrolet Equinox, Malibu and Captiva and the GMC Terrain. The 6T45 shares its overall layout and casting family with the smaller 6T40 but is not a universal swap between the two - match the casting marks, pressure switch layout and connector count on your original unit against the listing photos, or send your year, make, model, engine size and VIN so we can confirm the correct revision before you order. If your vehicle turns out to use the lighter-duty 6T40 instead, our 6T40 valve body listing covers that side of the family.
Change the fluid and filter in the same job as the valve body swap so wear debris from the old unit does not circulate into the new one, torque the mounting bolts in GM's specified sequence rather than corner to corner, and refill with DEXRON VI ATF. A 6T45 pump is worth inspecting at the same time if the original complaint included a slow or delayed first engagement, since a worn pump and a worn valve body can produce overlapping symptoms. Pair the valve body with a 6T45 shift kit if you also want crisper shift feel rather than just a return to stock calibration. Clear all codes and run the TCM's adaptive relearn after installation so the computer re-times clutch fill against the new unit instead of the worn one it replaced.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
They share the same overall layout and casting family, but the 6T45 is built for higher torque applications like the 2.4L-equipped Equinox, Terrain, Malibu and Captiva. They are not a universal swap for each other - match casting marks and connector count before ordering.
Remanufactured and bench-tested - every bore, check valve and solenoid connection is verified on a test stand before it ships.
A harsh or flared 2-3 shift on throttle release, slipping between gears, torque converter clutch shudder, and limp mode with a stored solenoid or ratio code.
Yes - GM's Preliminary Information PI0724B documents a harsh 2-3 shift on 2011 Equinox, Terrain and Captiva 2.4L models traced to this valve body, and pressure switch rivet failures were common through 2012 production.
DEXRON VI ATF.
A filter and pan gasket kit, the pump if there is a delayed first engagement, and a shift kit if you also want crisper shift feel rather than stock calibration.
