10L80 Tcc Solenoid, new other (see details) and ready to install. Fits the 10L80. Ships fast from the USA.
Read this first: although this page is named for the 10L80 TCC solenoid, the part that ships is a complete eight-piece solenoid set for the GM 10L80 and 10L60 ten-speed, and the converter clutch solenoid is one of the eight. That makes it the right buy for a 2017-up Silverado, Sierra, Tahoe, Suburban, Yukon or Escalade with converter shudder, lockup codes, or a mix of shift complaints where you would rather refresh every solenoid while the valve body is out than replace one and go back in later.
The 10L80 uses eight solenoids mounted directly in the valve body casting. Solenoid 8 controls the torque converter clutch. It is a normally low variable force solenoid: with no current it lets the converter stay unlocked, and the control module raises current to apply the clutch and hold lockup at cruise. Because the module modulates lockup rather than slamming it on, a worn or sticking solenoid shows up as slip or shudder before it shows up as a hard failure. The other seven in this set are the six linear shift solenoids, which time each clutch apply, and the line pressure solenoid.
Converter shudder is not always the solenoid. Old or wrong fluid, a worn converter clutch and wear in the main pressure regulator bore all cause the same feel. Start with fluid condition and level, then watch commanded versus actual converter slip on a scan tool. A solenoid that is commanded on while slip stays high points at the control side. Our 10L80 shift solenoid testing guide covers resistance and command checks for each solenoid, and the valve body testing guide explains the bore wear that can mimic a bad solenoid.
This set is listed for the GM 10L80 and 10L60. The 10L80 was used in 2017-up Chevrolet and GMC full-size trucks and SUVs and the Cadillac Escalade. GM changed the valve body around late 2019, so lay the old solenoids next to the new ones and match connector colors and body shapes position by position before you install. If you want us to check first, send your year and VIN. You can see every part we stock for this transmission on the 10L80 parts page.
If the fluid came out dark with clutch material in the pan, solenoids alone will not fix it; look at the 10L80 master rebuild kit. Towing trucks that run hot also benefit from the 10L80 transmission cooler.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A full set. This listing ships eight solenoids for the 10L80/10L60: six linear shift solenoids, the line pressure solenoid and the TCC solenoid.
If the TCC solenoid is sticking or weak, yes. Shudder can also come from degraded fluid or a worn converter clutch, so check fluid condition and commanded versus actual converter slip first.
Not always, but once the valve body is out, replacing the set costs little extra labor and removes the chance of a second solenoid failing soon after.
DEXRON ULV only. GM lists a fluid change of 7.7 liters, about 8.1 quarts. Do not mix in older DEXRON VI.
Yes. Reset transmission adaptive values and perform the relearn with a scan tool, then drive through several converter lockup cycles to confirm.
