As some of you know, I have been collecting parts for a Cummins build. One issue I wasn't settled on was the transmission. Well, it looks like I will be going with an Allison that was behind a 2008 Chevy 2500 Duramax.

Here's my question: Is there a way for a 6bt to be setup to defuel with the Allison? it's my understanding that this is necessary for the Allison to prolong it's life. Are there other options without defuel between shifts?
