I am interested in installing an Auto Tranmission cooler on my 99 max. I was just wondering how hard it was for you guys to install one or how much it would cost to have installed.

 

its not that hard! Thanks to mtrai760 who installed mine. all it is, buy the hayden 403 or 404... i bought the 404 and you need some extra lines. then just plug one end to the other. its pretty simple!!

 

I put one in my 3rdGen last week. It is a pain, but it is not hard. Just be sure to figure out which line is the return from your radiator. Search the forums; I am pretty sure they are detailed directions floating around here somewhere.
