I should say no rock crawling for me. I more interested in the OD than anything. Single digits MPG sucks at X.XX per gallon. Its in a wrecker that I use every day. I just know that the 400 will puke it guts one day and I don't mind to manual shift. For the price of the adaptor, I would prefer to use the 208. I have a 4500 4x4 trans in stock and have a good 208 also.

Something else I was thinking about would be using a 4L80 with a 208, but then again I would have to splurge on a stand alone computer.

Any idea what the lenght differance is on these 3 combos? Just wondering how the 4wd drive shifter holes will work...
