Chevrolet Tahoe Transmission Fluid

Which transmission fluid the Chevrolet Tahoe uses by model year and transmission, and how to check the level.

Quick answer

DEXRON ULV (2021 gasoline Tahoe owner's manual); other years and engines may specify DEXRON-VI — confirm for your vehicle. Dipstick: Some years. GM has used more than one automatic transmission fluid across these years. Frequent towing shortens service intervals. Fill capacity and change interval depend on your exact year, engine and transmission, so they are not listed here — use your owner's manual.
