2015 3500DRW towing a 42' enclosed stacker car trailer.
I've gotten 200k miles out of the stock trans, but it's time for more grunt.
Truck is currently running on a Raceme Ultra tuner, so I have the ability to program trans tune.
Seeking some input on my options of building my current trans, or going with a already built one.
Trailer is in the 20k lb area
