I am at a location in which our supporting elements provided our unit the C7 engines that were meant for the MATV vehicles and I was trying to overcome any differences in each vehicles engines as well as transmissions. The vehicles we have are the Caiman and Caiman Plus which has a C7 with Allison 7 speed automatic transmission with transfer incorporated with the transmission assembly. The problem is the MATV has an Allison 6 speed automatic transmission and therefore I was attempting to reprogram the ecm to the similar settings that the current Caiman vehicles have. The only issue we currently have is a non comm from TCM. We have done this but there are some parameters in which we have no rights to change. I am looking for a solution but I have a feeling the only fix is to reprogram the TCM for the vehicle to match up with the different ECM. Any suggestions would be appreciated.
