RV Cummins Swap - #3 - Transmission

This video is a little bit longer again, but it covers everything you will need to know about Allison transmissions and why I chose a 1000/2000 series to mate up to the 12V Cummins, which is the ultimate "Dream Combo".

Good call, 26:00 you saved a lot of money 💰 using a bus transmission. A Allison from a Duramax would of cost a lot more..to buy a adapter plate is over a 1K plus .what do you think the harnesses ,brain and what ever it takes to get the transmission to work?

As I had mentioned, I went to Jason at Transmissiontuner.com. Being this is a custom application, I had to build the harness myself. He sent me the TCM, all the connectors, plugs, a prewired main relay, wires, split loom and friction tape. It was maybe just over 1k for that. There is a base tune in the TCM. Once the RV is on the road, he will tune it remotely. I will drive the RV and he monitors and checks stuff in real-time and make any adjustments he sees fit. I’m editing a new video today I’m going to post up and it will show the harness.
