    isn't there any mention at all in any service books that came with the truck?

    you could also go to any dealer parts dept and ask there as well. even general truck repair garages should have that info.

    That would be gender fluid - trans fluid is, err - different.

    I'm guessing a semi synthetic 75-90W , a quick call to dealership with the last 6 of VIN should confirm.

    So I did this thing we call 'Google it'. I opened up my computer and put 'dt12 transmission fluid' into the search bar and you'd never guess what came up.

    Seeing how the D12 is not a full automatic but an "Automated MANUAL Transmission" I would use the same full synthetic 75W-90 that I would use in any manual transmission.

    I took 'safe search' off,

    There's many good references to 'R2D2 on a trans mission in the galaxies'
