2001 4x4 4.7 auto 68k. I understand it's a good idea to add a tranny cooler. I am getting ready to look around online for a kit and instructions.Anyone have any recommendations as to procedure or brand etc.?

 

I put one on my 2000 Durango several months back. If you do a search, you will find many discussions. I put on a Haynes from Napa, spliced it in the line after the stock radiator cooler. I wanted maximum cooling for towing, so, I put it in front of the condenser. Start to finish about an hour. Easy, no problems.
