to make an allison shift nicely enough for daily driving a light duty pickup truck WITHOUT shift energy managment? If you wanted to put an allison 1000 behind a 12valve mechanical cummins you could use a TCM thats calibrated to work ONLY off TPS (and input/output/turbine speed), but it would have no SEM or data communication with the ECM, so I cant see how its possible to have it working "nicely" like the allison's do behind the duramax's. Plus with a modded cummins and big power, wouldnt even a built allison be destroyed without SEM? I would think so... Run a PPE ET eliminator for a while and see how much your trans will hate life :D

so if all that is possible why did everyone (PCS and ATS) give up on a standalone TCM? Just use an allison TCM thats calibrated to work only off of throttle position.....

I think not. You still talking about that?

Nothing. They just want to say they have an alli behind their Cummins.

Ben i think Braydon(sp?) put an allison behind a cummins. IN an s10 too if im not mistaken.

now THERE'S an interesting job.

he did, in a 24valve cummins I dont know how he has the TCM operating tho, whether its interfaced with data to use SEM or it uses no SEM (and probably shifts like garbage)
