OK, that sounds great and I know you're very determined to get this done. I hope that engine will run on the VX PCM with the drive-by-wire converted to the VX cable throttle set-up. Getting the new engine wiring hooked up to the existing connections that run into the cab when it's designed to connect to a totally different PCM under the hood will be a challenge. For the tranny, I'm sure either engine will bolt up to either tranny. I'm just saying the Axiom tranny may have different components and internal electronic controls, so the Axiom tranny may need the Axiom PCM, and the VX tranny may need the VX PCM. If you're using the VX PCM the tranny and TOD are not an issue. It's just a matter of getting the new engine hooked up and running on the VX PCM. I hope it all goes well.
iamironman, my previous response was not solely directed at you, but also a general response to the whole concept of the Axiom engine swap questioned in the first post of this thread.
