Chevrolet Silverado Transmission Fluid
Which transmission fluid the Chevrolet Silverado uses by model year and transmission, and how to check the level.
Quick answer
DEXRON-VI or DEXRON ULV depending on model year and transmission — confirm in your owner's manual. GM bulletin 18-NA-355 specifies Mobil 1 Synthetic LV ATF HP for the torque-converter shudder repair on covered 2015–2018 Silverado 8-speed automatics. Dipstick: Not confirmed for every year — see your owner's manual. Diesel and heavy-duty models may use different transmissions and fluids. Fill capacity and change interval depend on your exact year, engine and transmission, so they are not listed here — use your owner's manual.
