2017 GMC 2500 Duramax: suggestions for ATF, Diff, P/S fluids

[Islandvic]

2017 GMC 2500 4wd CCSB Duramax base model, 60k miles, no mods.

Wanted some suggestions for ATF, diff, P/S fluids, etc

I might buy truck from a friend for a decent price.

Thank you

It depends on how much you want to spend for fluids.

The owners manual will provide the specs needed for the fluids. Any choice you make from the major oil companies will be a sound choice.

Tes295 approved trans fluid i would guess for the allison 1000. Delvac 1 atf is top notch
