Figured id throw in an update. It works as advertised, I like it and id buy another if i needed to. My only complaints are that when you turn the BD on, it briefly unlocks the TC. If you are trying to slow down that makes it a pita waiting for the tc to lock back up. I rarely drive with the BD on until i need to lock a gear out or manually down shift. Its not a big deal, definitely not a deal breaker just need to remember to bump the BD on before you want to start slowing down. The other gripe is that 2-3 times now after using the bd to down shift and for breaking it has locked/frozen up and leaves the vgt wide open, shifts get very erratic and it wont reset until you cycle key power. It doesnt happen very often but when it does it kinda sucks that you have to pull over and shut the truck off and restart before you can take back off.
