Ten-piece valve body solenoid set for the GM 10L80 10-speed, for harsh shifts, converter shudder and solenoid performance codes.
A GM 10-speed that shifts harsh into 2nd, flares between gears, shudders like a slipping torque converter at cruise, or has thrown a shift-solenoid or pressure-control performance code is usually telling you one or more of the ten solenoids on the valve body have gone weak, not that the whole unit is scrap. This kit replaces every shift and pressure-control solenoid in one pass on the 10L60, 10L80 and 10L90 used in the 2017-up Chevrolet Silverado 1500, Tahoe, Suburban and Camaro, the GMC Sierra 1500 and Yukon, and the Cadillac Escalade, CT4, CT5 and CT6.
The GM 10-speed runs six clutches through a stack of variable-bleed pressure-control solenoids plus the shift solenoids that direct line pressure between circuits. Each solenoid controls apply pressure on one specific clutch, so a single weak unit does not take the transmission out of service - it shows up as one bad shift, one shudder complaint, or one stored code while everything else still works, which is exactly why rebuilders replace the pack as a set rather than chasing one solenoid at a time. Our EPC solenoid symptom guide breaks down which clutch each circuit feeds and how a weak one presents.
Pull codes first - GM's service bulletins on this 10-speed family (6L80 through 10L1000) catalog harsh shift, shudder, surge and overheating complaints that trace back to twisted cooler lines and weak solenoid circuits rather than a cracked valve body casting, so a scan tool reading plus a fluid check rules out the cheaper fixes before you commit to a solenoid swap. Our shift solenoid symptom and testing guide and valve body symptoms guide both walk through isolating a solenoid fault from a sticking valve bore.
This set fits the valve body used across the 10L60, 10L80 and 10L90 as installed in the 2017-up Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade, CT4, CT5, CT6 and Camaro. The bleed solenoids are not interchangeable between circuits, so note which bore each one came out of as you remove them. See the full 10L80/10L90 parts collection for the rest of what we stock for this transmission, including the complete valve body if the casting itself is also worn.
Drop the pan and filter first so metal or clutch material from the failing solenoid circuit does not recirculate through the new ones, then pull the valve body and move the solenoids one position at a time so each replacement lands in the exact bore the old one came out of. Seat the wiring harness connectors fully, torque the retainer hardware to spec, and refill with DEXRON ULV - GM's published capacity for this family is 7.7 L / 8.1 qt. Clear the adaptive learn after reassembly so the TCM relearns clutch fill times against the new solenoids instead of the worn ones; skipping that step is the most common reason a fresh solenoid kit still shifts rough. If the valve body bores themselves show wear rather than just the solenoids, pair this kit with a full 10L80 valve body or 10L90 valve body instead of solenoids alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes - the 10L60, 10L80 and 10L90 share the same valve body solenoid layout, so this 10-piece set fits all three as installed in the 2017-up GM trucks, SUVs and cars listed above.
You can, but most rebuilders replace the whole pack during a valve body service because all ten solenoids share the same fluid and heat history - swapping one and leaving the rest often means a comeback within a few months.
DEXRON ULV ATF, filled to GM's published capacity of 7.7 L / 8.1 qt for this family.
Yes - clear the adaptive learn so the TCM relearns clutch fill times against the new solenoids. Skipping this is the most common reason a fresh kit still shifts rough.
No - this is a new aftermarket set supplied loose without a retail box, not a remanufactured or OE-boxed kit.
Pair this kit with a complete 10L80 or 10L90 valve body instead - new solenoids in a worn bore will not fix a hydraulic leak inside the casting.
