Has anyone done the 6BT cummins (24 valve) swap and used the same 4L80E tranny? I have an 1151 with a turbo and I am not happy with the power. I also have a free cummins motor. Any help would be appreciated.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Lol...right after I put the post in, I tried to put it in the right place and couldn't figure it out. Thanx brother!Moved to appropriate forum.
G56...It isn’t the horse power that kills the automatics. It is the relentless torque and compression stroke power surges. Even the NV4500 manual had to go through several upgrades to handle the 6BT over the years. It never did get “bullet proof.” I suggest that whatever transmission you end up going with. Get 2. Don’t build the second unit until you figure out what fails on the first unit. Maybe by your 4th or 5th generation of improvements you will have THE 6BT automatic set up.
Kind of like Jericho Transmissions:

The 4BT is what these things should have had OEM. Similar power, 10 times the life expectancy, and it'd fit better.Use a 4BT if you want less weight
Any update on how this project is going?Has anyone done the 6BT cummins (24 valve) swap and used the same 4L80E tranny? I have an 1151 with a turbo and I am not happy with the power. I also have a free cummins motor. Any help would be appreciated.
It was a 4B, Frito Lay had a fleet of them, like 200 nationwide.Interestingly enough there were some van or bus applications that used the 6BT and a 4L80, that adapter angled the engine for clearance, I wonder if that would be useful in a HMMWV conversion????
I have no idea what mods were done to the engine as far as oil pan/pump pickup that may have been necessary
It looks like the 47RH is the preferred trans for many swaps, no computer and it can handle the 6BT power.
What is behind the 24V now??
