700R4 2WD vs. 4WD

I would avoid it. 700 are not up to the abuse of 4WD.

They handle it fine, both my buddy and myself have 700's in our 4x4's. My buddy runs his truck off road all the time and it never gives him any trouble. My current project has a 700 I plan to rebuild (still works, just rebuilding the whole truck cause it has 340,000kms) and run. I've run 700's in some of my older trucks and never had problems, and one of them was a truck I would run in the mud. Biggest thing is when really working the 700 keep it out of overdrive. I've towed with 700's and never had a problem, same thing keep in in drive and out of overdrive and it's fine. Helps to beef up the coolers and if you rebuild beef up the internals while your at it.

X2, Tranny temp gauge is your friend with a 700. I found out the hard way but I built mine after I toasted it and its survived some severe abuse in a 2wd with a mild small block and I swapped shafts and it gets abused in a 4wd now. Not a mudder 4wd but it gets worked pretty good.

i dont know nothing about these transmissions. are 700s really that bad in a 4x4? i have heard that that the 400 is bulletproof, its what i have. and i bought my rig just for going off road

If you are going to off road your truck and don't plan to drive it at highway speeds much or care about fuel economy the th400 is your best bet. It is a strong transmission, and being most off roading is done at low speeds you don't need the overdrive. The th400 is the better transmission for work, but the 700r4 has the fuel economy on it's side, which is why I use it. My trucks see a good mix of on and off road and highway driving. Another option is the 4l80e, but you'd need a controller for it as it's electronically controlled. It's basically a 4 speed th400.
