2014–2018 Chevrolet Silverado 1500 fluids: common questions
What transmission fluid does a 2014–2018 Chevrolet Silverado 1500 take?
- 6L80 6-speed: Dexron VI ATF, pan drain-and-fill ~6 qt, side-plug level check. 8L90 8-speed (6.2L from 2015, some 5.3L 2017–2018): use only Mobil 1 Synthetic LV ATF HP (blue label) per TSB 18-NA-355, the original Dexron HP fluid is implicated in torque-converter shudder..
