This begs the quesion why would you want to do this? The 6spd Allison is Not superior to the 6spd Torqueshift. The Torqueshift takes more abuse than the Allison.

Allisons have been used behind the 6.0 powerstroke in the F650s so it is possible. Here is a link to the 2007 build guide. Note its the 5 spd allison.

Don't be fooled by the Allison name badge. In my experiences with the Torqshift and the Allison, I definitely think the Torqshift is a far superior tranny, not to mention that it will take a lot more power without needing an update kit like the Allison needs. I compared the two descending down a 8% grade while towing the same boat and the Torqshift did a much better job at maintaining the speed as well as not overheating. The Allison is at max capacity with the power levels of the current Duramax output, whereas the Torqshift is barely over half capacity with what the PSD is putting out. Think it over long and hard before going down a costly road.

To clarify those that do not know the torque shift actually has 6 forward gears but it uses a strategy of 5 of the 6 when cold and different 5 strategy when warm. I can't recall if it is 3rd or 4th that gets skipped depending on if it is warmed up.
Because it uses only 5 forward gears in any strategy it is known to be a 5 speed tranny. Contrary to the newer Alison that uses all 6 forward gears regardless warm or cold operation.
Stock tranny form form my opinion the torqueshift is better than the Allison - marginally; contrary to the reputable name. If your are considering going through the trouble of pulling an Allison apart to improve it for your high HP needs and more trouble and money to put it behind a powertroke it would appear more economical and easier to get a reputable trannies from company such as Suncoast for the best torqueshift.
My opinion but eveybody will have one.
If you or someone else goes ahead with an Allison tranny behind a 6L please keep us informed.

Cold Engine = 1,2,3,4 & 6
Warm Engine = 1,2,3,5 & 6
Gear Ratios"
1st = 3.09
2nd = 2.20
3rd = 1.54
4th = 1.09
5th = 1.00
6th = 0.71
The TorqShift also has the "Tow Haul" mode which alters the shift points based on load and driving style.
