Really good numbers for just a farm truck LOL ol nessy did a good job!
3745 miles. 12 states. 36' gooseneck trailer in tow. The truck did very well including going dropping down out of Denver into New Mexico going through a couple of mountain passes and traveling at a rather good clip of speed across the high plains. Admittedly the transmission did start to have some issues by the end of the trip and I did come the last couple hundred miles home in transmission limp mode..... at 65mph.... so I am not complaining. Time to refresh the transmission (that was built in 2007 and has 100K miles of compound turbos on..... lol).
Towing would be so much nicer with a 6 speed auto instead of a 4 speed auto. It comes down to the amount of gears available. Plus I can run 4.30 gears with the Allison and have the same rpms at 70 as 3.73 in the 4r100. Better for towing. Plus the Allison has a lower first gear, better for getting big loads moving.Why would you do an Allison???
