Duramax Swap-tranny/tcase questions

[uao85]

The Allison 1000 is the automatic used behind the DMax in GM pickups. A 4L80E won't last long behind a 600+ lb-ft engine. As for the manuals, I think the NV4500 is probably a bit light. The NV5600 or other similarly rated manual would be better.

the blue crew cab over on dieselplace.com that swapped a duramax has done some work to his and is using it as strictly a sled pulling truck, and he has an nv4500/np205 and havent heard any complaints. Plus the countless cummins trucks out there with chipped etc etc etc engines running around. Maybe the only downside to a nv4500 and power running through it is the 5th gear upgrade. I dont think its such a bad choice, heck if I were going for a simple low budget swap, this would be my choice. It eliminates the need for the body harness and computer, and you can just have a stand alone controller and harness for the engine.

Ok so after some more research on thedieselpage.com I could go this route:

"If you want to tone down the Dmax, you could run a TH400/4L80-E. This would allow you to use your existing transfer case (or those that work for the 80's drivetrain). If you want the Allison and HD 261/263 transfer case, you could swap in a Dana 50/60 Ford or Dodge front axle, which has the pumpkin on the correct side for the new style transfer cases."

So what do you guys think?

Subscribing to this thread because I'm also interested in a Duramax into K5 swap.

Yeah, I've already been on that site more times than I can count doing research. Thanks though.

What about a powerstroke??????? I thought about it. I love powerstrokes. Nothing beats a good International

Nah if I end up not doing the Duramax the only other options are 6.5 Turbo or Cummins
