jason at transmissiontuner dot com is where you can get a programmable TCM.. he also sells a cable operated throttle box and he can make you a wiring harness for your chosen transmission..
you will want to source a late 06 to 2009 transmisison.. in 2010 some changes were made. (I think it was 2010) ...
you can ask jason but i believe his setup is designed for the 06-09. my transmission was built off of 09 Specs.. i have run it with both an A41 and A51 TCM.. Odd numbers like this are Medium Duty TCMs. that most often sport "auto" throttle or "J1939" mode.
your 2400.. most 2400s that ive seen where put into heavier trucks and were therefore SAE2 Bells.. you are going to want to find one that has an SAE3 bell and appropriate tailshaft. if your bus is hydraulic brakje you will need to modify you existing parking brake, find a donor on a 2000 series bus, or buy a new park brake assembly and cable bracket.. not applicable to air brakes..
if you have never Tuned an engine or transmission then I would consider paying jason to do your tunes.. if you screw up a trans tune you can cause a Bind up of 2 drums and scatter parts on the freeway... its actually not super easy to do but just saying EFI live is capable of making carnage..
ive done this sort of thing for quite a few years so I took it easy and only did small changes at a time.. last I checked I have over 240 revisions of calibration files ive made for my allison.. i am set up where i can make a change on the fly.. more than once ive been driving and thought.. "damn I wish 6th gear wouldnt come on so easily.. it it needs to come on later".. next rest area I make a change (using one of my digital dash tablets).. save it program it. and off i go..
im not sure where to source a 2400 that is built up or custom.. 1000s are easy.. CAC does it all the time.. (in fact they specialize in mounting allison 1000s to cummins 5.9s).. they are a class-act company. I wanted a progrannable TCM which they didnt have so I got one from jason.. but CAC could sell you a system that you could walk out the door with and install..
my trans came from there and so did my harness. (and also one of my TCMs).. I have had ZERO issues with the wiring or the transmission. I just go... so if you want a one stop shop they can set you up.. their TAP-Shift product is mature now too.. when I was getting started it was not yet out.. Tap shift allows you to manually select any gear like the MD3060 guys do..
you can ask them about a 2400. or possibly a wide ratio planet set can be put into a 1000.
I dont discuss pricing typically as oftentimes vendors cut me deals in exchange that I give them detailed feedback and suggestions on the products and help them to improve.. I dont want to push out pricing that is or was not General..
