[QUOTE="Hotrodtractor, post: 321567, member: 25"] Not wanting to start an argument or question your decision - but I tow very heavy (I plead the 5th heavy...) with my Allison in my Dmax - the Dmax is rocking about 420hp in the tow tune with compounds - it is a super nice flat power curve - and I basically never leave 6th gear while on the interstate. Occasionally I will drop it down to 5th only to counteract a current tuning problem I have where my CP3 literally can not supply enough fuel volume to maintain the injection pressure and PW I am need to maintain speed at a low RPM. Yes - my transmission is "built" with an off the shelf set of parts in a common kit - but the kit cost is sub $3K - the Allison 6 speed trans I bought for my project out of a junkyard guaranteed good for $1K delivered - and I have the benefit of an almost plug and play Allison computer and harness unless I want to figure out how to enable torque limiting on my swap. So that would put you at $4K ish. Plus you could have the benefit of getting an Allison 1000 with an SAE bellhousing and an off the shelf SAE bellhousing adapter for the Cummins and bolt them together for significantly cheaper than custom making an adapter. Again - I want to see the 6R work - I think its cool - but I felt I needed to add a little different perspective as I think its really a wash at the end of the day on which transmission you choose because each has their own unique set of headaches that need conquered, but the the Allison has people that has been there and conquered them before. Good luck and I hope the journey through this project is smooth as possible for you. [/QUOTE]
