I have had a LOT if inquiries on the 48re conversions. Just a couple things to clear up. If you are thinking about this swap, you need to either have the ability adjust the tunes yourself(which we will help you with) or be willing to spend a little extra money to have us tune it. It does not come pre tuned. It will take a little time to setup a tune for each truck because everything is a variable. Like tire size, gear ratio, turbo setup, fueling mods, towing or competition, etc. I just want everyone to know this so there will not be any surprises or unexpected costs. I do believe this is the ONLY option to having a dependable transmission behind your 6.7 cummins. I do not know of any 68RFEs that have held up to much power as of yet, and honestly don't think they ever will. If anyone has any other questions, feel free to contact me. Thanks
