10L80 Solenoid Kit, new other (see details) and ready to install. Fits the 10L80. Ships fast from the USA.
This is a new six-piece set of clutch control solenoids for the GM 10L80 ten-speed, the automatic in most 2017-and-later Silverado 1500 and Sierra 1500 pickups, the Tahoe, Suburban and Yukon, and the Escalade. It cross-references to solenoid numbers 24046408 and 24268036, which interchange with Ford's HL3P-7J136-AA and HL3P-7J136-AD for the shared 10R80 design. Owners usually come looking for it with a truck that bangs into one gear, flares between shifts, slips in a single range, or has stored a control solenoid code that came back after a fluid service.
The 10L80 has six clutches, and each one has its own solenoid. GM numbers them control solenoid valves 1 through 6. They are linear force solenoids built into the valve body casting, and no fluid passes through them. When the control module sends current, an armature pushes a pintle out about 0.090 in. to stroke the clutch control valve behind it, and that valve meters line pressure into the clutch. Because several gears share each clutch, one weak or misaligned solenoid upsets every shift that uses it. The 10L80 also has solenoid 7 for line pressure, solenoid 8 for the converter clutch and a default disable solenoid. Those three are not in this six-piece kit. The 10L80 pressure control solenoid and the 10L80 TCC solenoid are sold separately.
A solenoid code on this transmission does not always mean the solenoid failed. GM bulletin 25-NA-014 traced P2732 with no Reverse and no shifts past third on some 2024 Silverado and Sierra 1500 trucks to a mis-stamped spacer plate and valve body wear, not the coil. On valve bodies built after late 2019, Sonnax reports that a worn feed limit low valve can set P0747 and cause a sudden drop to second gear. Check fluid level and condition first, then use a scan tool to compare commanded and actual clutch behavior gear by gear. Our 10L80 shift solenoid guide explains the tests, and the 10L80 valve body guide covers the bore wear that mimics a failed solenoid.
The kit is listed for GM 10L60, 10L80 and 10L90 valve bodies in Chevrolet, GMC and Cadillac vehicles, including the Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade, Camaro, CT4 and CT5. It is not for the Allison 10L1000 in the heavy-duty trucks. GM changed the valve body during production, and fitment can vary by model year, engine and valve body version. Compare the part number on your original solenoids and the connector color before ordering, or send us your year and VIN and we will check it. Other 10-speed parts are on the 10L80 and 10L90 parts page.
GM lists the 10L80 fluid change at 7.7 L, about 8.1 quarts. If more than these six solenoids are suspect, the 10-piece valve body solenoid kit adds the pressure and converter solenoids in one order.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Six clutch control solenoids, the ones GM numbers 1 through 6. The line pressure solenoid, the converter clutch solenoid and the default disable solenoid are not included.
It is listed for 10L80 valve bodies in the Silverado 1500, but GM changed the valve body during production. Match the part number on your old solenoids and the connector color, or send us your VIN.
No. The kit is not for the Allison 10L1000 heavy-duty ten-speed.
Yes. The control module has to be loaded with the solenoid performance data after solenoids are replaced, then the shift adaptives need to relearn.
Not always. GM has traced P2732 on some 2024 trucks to a spacer plate and valve body wear. Diagnose the valve body before replacing solenoids.
DEXRON ULV only. GM lists the fluid change at 7.7 L, about 8.1 quarts.
