Everything You Need to do a 68RFE Dodge 6.7L Cummins Transmission Swap.
We get a lot of swap related questions, and that is great, we are here to help, but I wanted to make a post to help educate anyone curious about what all parts are needed to swap a 68rfe truck to a 48re. We have a complete Comp 1 transmission + parts and controllers kit listed online for $8737.90 (not installed).
You will still need to source a 48re core transmission and converter if you don't want to be charged a $1500 core charge. They continue to be harder to find so we'd rather have a 48re core then your core money. The kit includes the parts and pieces you need to complete a swap and additional options you can add to this kit are aux trans coolers, Comp2 or Comp 3 upgrades, and soon a Anteater Pro option over the Classic.
The driveshafts from the 68rfe are reusable, but the Tcase input shaft needs modified. If its a New Process Tcase (NP271/NP273) we can sell you a replacement tcase input shaft that fits the 48re output shaft, or if its a Borg Warner Tcase or a fat output shaft transmission, we usually just machine 3/4" off the tcase input. If your looking to do this swap yourself or with a buddy, this kit will get you what you need to get started. If you have questions contact.
