Looking to swap a trans in my truck I have a 2008 c5500 with a 24 valve Cummins in place of the 8.1. Truck has a ally 1000 in it we tow a lot and want to go to a manual. Looking at a rto11607ll it’s a 7 speed with overdrive I believe. I have the trans already that’s the reason for using. I needed something with overdrive can anyone give me any info on it good thoughts ?bad thoughts ? How about clutches and suggestions I’m guessing it will be a cable style engagement? Thanks guys !!
