10L80 Solenoid Kit 2019, new and ready to install. Fits the 10L80. Ships fast from the USA.
This listing is a PPE deep cast aluminum transmission pan, part number 128051100 in raw finish, for the Chevrolet Silverado 1500 and GMC Sierra 1500 with the 3.0L Duramax diesel and the 10L80 ten-speed. It is not a solenoid kit. Owners shop for it when a 3.0L truck that tows runs high transmission temperatures, when the factory pan has been dented on a rock or curb, or when they want a drain plug and more fluid in reserve before the next service.
The pan is the fluid reservoir the filter draws from, and on the 10L80 the factory pan has no drain plug. PPE's pan is cast from A356.0-T6 heat-treated aluminum with external fins and holds about 4 extra quarts. The extra volume does two jobs: the fluid takes longer to heat up under load because there is more of it, and the fins shed heat from the sump. It also comes with a 304 stainless magnetic drain plug with a neodymium magnet that collects fine steel wear, and a 1/8 in NPT port with a plug installed if you want to add a temperature sender. The pan is built to work with the factory gasket and filter, which are not included.
Heat matters more on the diesel. GM bulletin 22-NA-182 notes that gas 10-speeds carry the thermal bypass valve inside the valve body and open it at 143 F, but on the 3.0L LM2 and LZ0 Duramax the valve is on the frame rail and does not open until 194 F. That is a lot of heat before the cooler sees any fluid, and extra sump capacity buys margin.
A pan treats heat; it does not fix a hydraulic fault. If the truck has harsh shifts, slips or a sudden downshift with P0747, read GM 10L80 transmission problems and the valve body recall first, because worn valve body bores cause many of those complaints. Check for a twisted rubber cooler line, which GM lists as a cause of overheating and DTC P27EC on some 10-speeds; the 10L80 cooler line replacement guide walks through it. If shifts are erratic with solenoid codes, see 10L80 shift solenoid symptoms.
The listing calls this pan a fit for 2019-and-newer Chevy and GMC 3.0L Duramax trucks with the 10L80. PPE dealers list part 128051100 for 2020-up Silverado and Sierra 1500 3.0L Duramax, so a 2019 diesel should be checked before you order. It is a diesel-specific part; do not assume it fits the 5.3L or 6.2L gas trucks, the Tahoe, Yukon or Escalade, or the 10L90. Confirm your engine code on the glovebox label (LM2 or LZ0) or send us your year and VIN. Other parts are on the 10L80 and 10L90 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing name, this is a PPE 128051100 raw-finish deep cast aluminum transmission pan for the 3.0L Duramax 10L80.
It is listed for the 3.0L Duramax only. Gas trucks and SUVs need a different pan, so send your year and VIN if you are not sure.
About 4 extra quarts over the factory pan, according to PPE's product information.
No. It includes the pan and a magnetic drain plug. It uses the factory gasket and filter, so order a new filter and gasket kit with it.
DEXRON ULV. GM lists a 7.7 L (8.1 qt) fluid change capacity; add the extra pan volume to that when buying fluid.
Only if heat is the cause. Harsh shifts with P0747 or a sudden drop to a low gear point to valve body wear, which a pan does not repair.
