10 speed

Anyone towing a 5th wheeler with the 6.7 and 10 speed? Would like to hear your opinion of the combination.
Thanks

Overall, it isn’t bad. I’m still getting used to the different shift points compared to a 6 spd. It short shifts going up, and holds higher gears coming down when not towing. While towing it does a good job staying in the right gear. The up shifts with a load are a bit firm, but not unbearable. I went from a 350 SRW w/ 3.55’s to a 450 DRW with 4.30’s, and I get the same fuel economy towing my Momentum, 10-11 mpg.

Works great. With the tow/haul and exhaust brake it stays in the right power band. Does a good job of figuring out which gear without issue

Scott, when we met at Gettysburg you were talking a new truck. Very nice along with your new goose neck setup. Maybe I'll get to see ya at next years meet. ENJOY!

Yes it was a nice upgrade. The old truck was great and I truly could have kept it but I have always wanted the 450. Time seem right to get it.

Best combination ever in my opinion. Like Senix said, T/H mode and exhaust brake make towing a breeze. My 10 speed is so smooth I have to watch the gear indicator to see it shifting.
