chevy 4L80e cummins conversion?

Howdy
Current 6.5 truck is getting tired and starting to sound loose. Has anyone done a cummins conversion with an automatic transmission? Just feeling out my options....
Thanks in advance!

You'll need some type of adapter and electronic controller to get 4L80e to work with the Cummins. I would also recommend a lower stall converter. That said, once you're finished you'll wish you would have done the conversion earlier. Much more power, better fuel economy and simplicity are a few of the advantaged.
