8L90 Sun Shell, new and ready to install. Fits the 8L90. Ships fast from the USA.
Please note: despite the title on this listing, this item is the internal transmission filter for GM's eight-speed, reference D154010, not a sun shell. It is the part you want when you are doing a pan-off service on a Silverado, Sierra, Yukon, Escalade, Camaro, Corvette, Colorado, Canyon, Express or Savana, or when a shudder, overheating or no-move complaint has you pulling the pan to look at the fluid and screen.
All of the oil the transmission uses passes through this filter on its way to the pump. The 8L90 and 8L45 use an off-axis, chain-driven pump, and Sonnax notes that this design is sensitive to priming and to anything that restricts its inlet. A clogged or poorly sealed filter means the pump draws air or struggles for oil, which shows up as low line pressure, delayed engagement and, in the worst case, a no-move condition. The filter also traps the clutch material and metal that would otherwise circulate through a valve body that is already known for bore wear.
A filter will not cure a mechanical failure, so look at what you find in the pan. Fine dust is normal wear; chunks of metal or large amounts of clutch material point to a deeper problem, and our 8L90 common problems guide helps sort out where it came from. If the truck will not move or engagement is very slow after a fill, read our 8L90 pump failure symptoms guide before replacing parts, because an unprimed pump and a low fluid level cause the same complaint.
D154010 is cataloged for the 8L90 (2015-2023), 8L45 (2016-2024), 8L80 (2023 on) and the 2024 8L90 N8X and 2023 8L45 N8R versions. Listed vehicles include the 2015-2026 Silverado 1500 and Sierra 1500, 2015-2017 Escalade, Escalade ESV, Yukon and Yukon XL, 2017-2026 Colorado and Canyon, 2016-2023 Camaro, 2015-2019 Corvette, 2017-2024 Express and Savana 2500/3500, and Cadillac ATS, CTS, CT4 and CT6. GM has revised the 8L family several times, so set the new filter next to your old one and compare the shape, the neck and the seal before you install it. If you are not sure, send us your year and VIN. See every part for this family on the 8L90 collection page.
Drain the pan and pull the old filter straight down, then make sure its neck seal came out with it rather than staying in the case bore; a leftover seal is a common reason a new filter will not seat and the pump sucks air. Lube the new seal with clean fluid and push the filter fully home. Inspect the pan gasket. If it is torn or hard, our filter and pan gasket kit includes a new gasket. Refill with DEXRON HP fluid only, such as Mobil 1 LV ATF HP; GM warns that other fluids can cause internal damage. GM lists a fluid change capacity of 7.4 quarts for the 8L90 and 8L45, so the level must be set with the engine running at the specified fluid temperature using the check plug, not by counting quarts.
If you tow or see high fluid temperatures, check that coolant and fluid flow through the 8L90 transmission cooler and the thermal bypass valve are working while the vehicle is apart.

No. The listing title is wrong. The part is an OE-style internal transmission filter, reference D154010, for the GM 8L90 and 8L45. If you need a sun shell, contact us before ordering.
Yes, it is cataloged for the 8L90 from 2015, the 8L45 from 2016 and the later 8L80. Compare it with your old filter before installing, since pan and filter designs have been revised over the years.
Replace it any time the pan is dropped for a fluid service or repair. GM's shudder bulletin calls for a full fluid exchange, and replacing the filter at the same time keeps old debris out of the new fluid.
DEXRON HP only, such as Mobil 1 Synthetic LV ATF HP. GM lists a 7.4 quart fluid change capacity for these transmissions, but always set the final level hot, using the check plug procedure.
Usually the old filter's seal is still stuck in the case bore. Remove it carefully without scratching the bore, lube the new seal and press the filter in fully.
