True. The Allison is a clutch-on-clutch design. Get it shifting too fast and itll hang up in two gears...not a good thing.Some one was telling me even modded the allison just does not shift fast enough and building a dodge auto would be cheaper and work better.
I like how it shifts fast. I believe another part of that communication is a momentary power reduction during shifts. I also don’t think the Allision is the cure all of transmissions. I like it for what it does, and they came out with the 5 and 6 speed first, but if you are going to throw power at it you better be ready to upgrade it just like every other transmission. I would love to feel how it shifts behind a Cummins though. I bet that would be a kick in the butt!True. The Allison is a clutch-on-clutch design.

The best racing trans is the Dodge 47rh/e/48re. Stock, yea they kinda suck. They do have a worse reputation than deserved though. But built, its the best for all out racing, maybe even sledpulling too.
You can swap an Allison in. People will say you cant because it needs to communicate with the engine for torque management. True, so all you do is fool it into thinking the Duramax is ahead of it instead of the Cummins. Fleece has a couple 12vs running Allisons, and obviously Suncoast has done it to.
