The 8-speed should be a better fit for the 6.4 gas. Gear spacing, should be a non-issue, even with 3.73 ratio.

The biggest downfall, in my mind, was that transmission in the 6.4. Plenty of power in the 6.4, but when towing up hills it would try to hold 4th too long and then eventually slam into 2nd and make the engine scream. Wouldn't even try to use 3rd. I hope this transmission fixes those kinds of issues.
