6L80 Solenoid Kit 2010-19, remanufactured and ready to install. Fits the 6L80. Ships fast from the USA.
This 6L80 solenoid kit is the complete remanufactured solenoid body with the transmission control module attached, the assembly GM calls the TEHCM. It is listed for 2010-2019 GM vehicles with the 6L80, including the Camaro, Silverado, Sierra, Tahoe, Yukon and Escalade. Buyers usually land here after a scan tool shows shift solenoid performance codes, a speed sensor code, or a truck that dropped into limp mode and will only hold one gear.
On the 6L80, GM did not use loose solenoids you can unplug one at a time. The shift and pressure control solenoids, the transmission computer, the input and output speed sensors, the fluid temperature sensor and the pressure switches all live in one unit that bolts to the top of the valve body inside the pan. The solenoids send signal oil to the clutch regulator valves below them, and the pressure switches report back which clutch actually applied. The line pressure solenoid in this same assembly sets how hard every clutch is squeezed. When any part of it fails, the computer either cannot command the shift or cannot confirm it happened, and it protects the transmission by locking into a fail-safe gear.
Not every 6L80 code means the TEHCM is bad. Check the connector at the case and the harness for oil wicking or damaged pins, and verify the fluid level with the hot check-plug procedure. Leaking end plugs and worn valve bores in the valve body set the same performance codes, so a hydraulic fault can look electrical. A line pressure gauge reading stuck near 60-68 psi with no rise points at the solenoid. Our 6L80 shift solenoid symptoms guide covers what actually fails and what only looks like it, and the 6L80 common problems guide covers converter shudder and clutch wear that can be mistaken for a control fault.
Listed for 2010-2019 GM vehicles with the 6L80. That range spans more than one TEHCM generation. Sonnax notes that one generation typically covers Chevrolet 2010-2013 and an updated generation typically covers Chevrolet 2011-2020, so the overlap years can go either way. Before ordering, read the part number printed on the TEHCM in your transmission and match it, or send us your year and VIN and we will confirm. The same unit must also be programmed with the software file that matches your VIN; an unprogrammed or wrong-file TEHCM can cause no movement or no upshift. See all 6L80 parts on our 6L80 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the full remanufactured assembly: the solenoid body with the transmission control module attached, known as the TEHCM. The 6L80 does not use separately replaceable shift solenoids.
Yes. The TEHCM must be programmed with the software file that matches your VIN. Sonnax warns that a wrong part number or wrong program file can cause no movement or no upshift.
It is listed for 2010-2019. Those years span more than one TEHCM generation, so match the part number on your old unit or send your year and VIN for confirmation before ordering.
Yes. The input and output speed sensors are part of the TEHCM assembly on the 6L80, so codes like P0716 and P0717 are often traced to this unit after the wiring checks out.
Replace the filter, pan gasket and case connector seal, and refill with Dexron VI. If clutches are burned or the valve body bores leak, those need repair too or the new unit will still set codes.
