Well I have sat here long enough a read to many false hoods about the allisons. So this is my 2 cent. im an alllison technician so here it is. An allison is proably the best trans on the market today. Allisons are in ever thing, buses,motor homes, trucks,tanks , fire engine ,etc. A built allison is beter than any ford or dodge trans. Now on to the next half. To get the 6th gear its all in the programing. Since you are not using the 1939 comunications with the tcm you have all u need in engine speed, turbine speed an trans output speed . Also power to the tcm an she will work. it wont throw an codes the will stop the trans from shifting. an since your not using the 1939 communication you will never see the check engine lite.

I have a question about the transfer case used. I know you can use a NV261 (manual) or NV263 (electric shift). are these transfer cases full time 4x? what I mean is when its in 2, does the front driveshaft spin all the time? also how much stronger is this case compared to the 241 dodge?
also is there a PTO on the 261?

I don't think the front driveshaft will turn unless the axle doesn't have CAD...they are tougher than the 241's but not as tough as the 271's in the 03-up Dodges!

would you be able to put a 271 behind the allison instead?
the max torque rating from NVG states:

NV241 and NV241HD- 5555lbft
NV261 -2564lbft
NV261HD -5430lbft
NV261SHD -5677lbft
NV271 -7890lbft

the difference in the adapters is size. flexplate is cummins and is solid. As far as TCMs go, I am not sure yet. I will get back to you tomorrow. I don't think I got your pm but I will check. The 261,263 has all the same gear selections as the dodge so no the driveshaft doesn't turn in two high. You cannot put a 271 behind a an allison because it has to have an output speed sensor on the tcase and the 271 doesn't have that. The 261 and 263 don't have provisioning for a pto, only the tranny itself does.
