hey guys i have a 06 cummins with a auto thinkin bout going to stick what all do i need in order to do the swap thanks

 

Your best bet would be to get a donor truck so you have all the parts! Thats a good place to start

 

Pick up a g56 manual trans. Under your carpet or floor mat you will have a plate over the transmission tunnel. Remove the plate, run the stick up threw the hole, an mount up the trans. Like Matt said find a identical wrecked 06 cummins with the G56 manual in it. Make sure you have a new clutch, go with south bend dual disc on that.
