We created a detailed guide showing all the steps necessary to flush your 6L80 transmission and change the filter. This guide can also be used to do a transmission fluid change.

NOTE PAN BOLT TORQUE IS 80 in lbs or 9 Nm NOT 90 Nm. sorry for the typo.

This video was created using my 2014 Silverado 1500 with the 5.3L V8. For this vehicle, GM recommends that the transmission fluid and filter are changed (not flushed) every 97.5K miles for regular service and 45K miles for severe service.

The 6L80 /6L80E (electronically controlled) Transmission is used in the following vehicles:

Chevrolet Corvette
Cadillac XLR
Cadillac STS
Cadillac XLRV
Cadillac STSV
Chevrolet SS
Chevrolet Avalanche
Chevrolet Silverado
Chevrolet Suburban
