You know, I have a BAM beefed up Velvet Drive. When I got it back it had a tag that said, ONLY USE TYPE F Transmission Fluid. I talked to the owner and he said that was the best for this application even though it is an older fluid than others. Maybe it has to do with different clutch material that he puts into the rebuild.
For the Torque of the 210 Cummins, you are probably fine with what the manual recommends.
