    M1078a1 Missing Transmission TCM

    I recently got a 2000 M1078a1 and after doing the receiving inspection the Transmission TCM is missing. I talked to the Allison dealer and they are unable to program a new TCM without the old serial # on the TCM have anyone had any luck with sourcing and getting a TCM flashed? Thanks
