6T45 Solenoid Kit, remanufactured and ready to install. Fits the 6T45. Ships fast from the USA.
The 6T45 is the heavier-duty sibling of the 6T40, and in North America it is best known behind the 2.4L four-cylinder in the Chevrolet Equinox, GMC Terrain and Captiva Sport. When one of these crossovers starts slamming the 2-3 shift, losing reverse, or setting a pressure control solenoid code, owners start shopping for a solenoid kit. This listing is a remanufactured seven-solenoid set for the 6T45 control module. Below is what it fixes, what it does not, and how to tell the difference before you spend the money.
Every 6T45 shift is a hand-off between two clutches, one releasing while the next applies, with no bands and no one-way sprag doing the timing for it above first gear. The TEHCM, the transmission computer and solenoid body mounted on the valve body behind the side cover, manages that hand-off through six variable pressure control solenoids and one on/off shift solenoid. One sets line pressure, one controls the converter clutch, and four meter oil to individual clutch regulator valves. In a heavier crossover the 6T45 carries more load than a 6T40 does in a compact car, so a solenoid that responds slowly or sticks shows up quickly as a bind or a flare you can feel.
A harsh 2-3 shift on a 2011 Equinox, Terrain or Captiva 2.4L is not automatically a solenoid. GM's PI0724B covers exactly that complaint on the 6T45 (RPOs MHC and MH7), reproduced by easing off the throttle just before or during the 2-3 upshift, and the fix is a TCM software calibration, not parts. If your shift only turns harsh in that throttle-lift situation, ask a dealer to check the calibration before replacing anything. The other common impostor is the 3-5-R clutch: a cracked wave plate drops reverse, 3rd and 5th just as a failed PCS2 does. Our 6T40/6T45 common problems guide explains both, and the delayed engagement guide covers slow Drive and Reverse. Once you are down to the solenoids, measure each one off the module: 3-5 ohms for the pressure control units, 16-20 ohms for the shift solenoid.
The listing has no year range. It is catalogued across the 6T40/6T45/6T30/6T50 family, and the photos show seven solenoids: three tan bodies, three black bodies, and one with blue seals. What decides fit is the control generation. For 2012, GM moved the Equinox, Terrain and the 2.4L Captiva Sport to Gen 2 controls, while the 3.0L Captiva Sport stayed on Gen 1. The eighth digit of the TEHCM identifier tells you which one you have: 1, 2 or 3 for Gen 1, B, C or D for Gen 2. PCS2 and PCS5 change position and function between the two, so match each new solenoid against the old one in the same bore before installing it. V6 Equinox and Terrain models use the larger 6T70 family and are not covered. Send us the year and VIN if anything is unclear.
If the fluid smells burnt or there is friction material in the pan, a clutch has already suffered. Pair the job with a 6T45 clutch module, and if the regulator bores are worn, a 2010-2017 6T40/6T45 valve body is the cleaner fix.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The V6 versions use the 6T70 family. This kit is for the 6T45 behind the 2.4L four-cylinder and related applications.
Possibly not. GM released a software calibration for a harsh 2-3 shift on 2011 Equinox, Terrain and Captiva 2.4L models when the throttle is released during the shift. Have the calibration checked first.
The 6T40 and 6T45 share the same control design and solenoid layout, and this set is catalogued for both. Fit depends on whether your module is Gen 1 or Gen 2, so check the eighth digit of the TEHCM ID.
Not for a solenoid swap in your original TEHCM. Clear the adaptive values and let the computer relearn over several shifts.
Dexron VI. Bring the transmission up to operating temperature, run it through the ranges, and let excess fluid drip from the level plug.
