I wasn't sure how to go about searching for this. Would it be possible to get a segment swap done on a 01 LB7 PCM that would allow an allison 6 speed transmission to be controlled? I imagine it would probably be necessary to run a 6 speed TCM as well, and make sure the wiring is correct. I know there is one aftermarket controller that makes it possible to do this but you cannot access it to make any changes other than what is preset and sent to you. Since I need to build a tranny anyway, I would like to use a 6 speed core if this is possible. It is my understanding that the transmissions are virtually identical physically. Thanks in advance for the help.
