Wonder what the engineer means by “driveshaft hammering”? **. Corrected: (crankshaft hammering). TY

Given the exact same axle ratio as the third gen, the new trans seems to have a better gear setup than the RC-62F, especially reverse:

1 - 3.98
2 - 2.02
3 - 1.32
4 - 1.00
5 - 0.85
6 - 0.7
R - 3.39

IIRC the transfer case low range is the same as the third gen, so crawl ratio is better in the new truck as well.

Jesus that 1st gear is short lol!!

 

Yeah the 1-2 parking lot shift will be interesting, although 2nd is lower sped than the previous gen trans... And you SHOULD have more available torque down low with the I4 turbo.
