Just curious about which gear would do best on the freeway, 3.55 in third direct or third in O.D.
I have another piece of marketing literature that contains a cool diagram showing the impact of the Truckstell on RPM as various speeds. I did some arithmetic and some art-work over coffee to add in the PG+OD RPM figues:
again if you right-click on the pic and choose View Image it is much easier to read.
At 70mph the figures in the diagram suggest and RPM of 2227 . . . so I think I will likely be stepping down to 1:1 on grades . . .inline with Beater's experience . . .
