ZF S6-650 vs Allison
Which of the 2 transmissions would you rather have for pulling a gooseneck trailer? I found a 2003 Duramax with the 6speed manual and I was wondering if they are as good or better than the Allison for pulling?So If anybody could help me out it would be greatly appreciated.

I think you will find that most of us that have one are bias and love them. I had a 01 Dodge with the 6 speed and i prefer my Duramax Alli combo hands down. The Alli is extremely simple on the inside and even someone with some halfazz mechanical ability can rebiuld it. The parts are fairly descently priced aswell. You will get many trouble free miles outa it.
