the DT-360 in the DEV is an SAE2 and the 1000 can be bought that way... and like yours its lates gen can be bought run with just a TPS... in fact CAC makes a "cable based TPS" thats designed to fit exactly in the bracket under the hood that an AT545 shift cable did.. and it uses this for the input of the transmission..
on that bus the carrier bearing plate bracket can be flipped aroud and its almost exactly the 3/4" Difference in the trans length from an AT545.. and the rear driveshaft slip yoke even with the air-suspension dumped all the way down still has over an inch.. so might not have to shorten either driveshaft..
on the newer Bus a 2100 series can be installed easily.. becasuse that is a T-444E motor the ECM is already capable of running an allison transmission.. that bus was offered with it as an option.. 2100 series in 5 speed mode.. a jumper wire on the ECM and then connecting the COmmunication bus to it and supposedly it will recognixe the allison when plugged into the Servicemaxx software and be ready to go... the ECM is already built with the code to run a 5 speed variant and shift it at the proper time..
that bus is already capable of running 70 MPH now that I turned off the vehicle speed governor.. I of course left the RPM limit set at the stock safe value of 2700.. though the books say it can easily be 3200 and not hurt stuff.. but its easy to see that the TQ / HP peaks are at 2500 or so ..alas running the RPM's up would only lead to less engine life.. the bus already has decent tires.. but when I do get new ones I'll probably go form 32" to 34" tires and lower my RPM's a bit more... with it using 19.5" tires they cost significantly less than the 11R22.5's I put on DEV... and tires cost significantly less than new transmissions.. lol
