I have a 99 Dodge 4x4 diesel. I did a 6 inch lift and installed 35's. I've gone through 7 trannies. If I blow this one again I'm going to swap it out for a manual. Just be prepare for that. My GMC (regular gas) has a 6 inch lift on 35's. That tranny held out for 135K miles. I rebuilt it and currently has 188K. I still have the dodge though. Love that turbo.
