2020 Diesel supplement says:

Automatic Transmission   DEXRON ULV Automatic Transmission Fluid (GM Part No. 19352619, in Canada 19352620).

 

fwiw, the HD 6 speed uses Automatic Transmission (6-Speed Transmission)    DEXRON-VI Automatic Transmission Fluid. 

 

 

And in the 1500 OM says

Automatic Transmission (6-Speed Transmission) DEXRON-VI Automatic Transmission Fluid.  (same as in HD 6 speed)
Automatic Transmission (8-Speed Transmission) DEXRON-HP Automatic Transmission Fluid.
Automatic Transmission (10-Speed Transmission) DEXRON ULV Automatic Transmission Fluid. (same as HD 10 speed)

Does the 2021 not have the spin on transmission filter?
