Transmission cooler

[Explorer0204]

Hello everyone.

I am considering adding a tow package to my Explorer. I know that it consists of 3.73's a transmission oil cooler and the class three hitch.

I don't plan on doing the gears as I don't tow over 3,500lbs often (once or twice a year maybe) so instead I was going to compensate by putting a massive trans cooler on it. Also, on my old Explorer that had the towing package I towed with 245 70 16s instead of the 245's so I assume that brought the theoretical axle gearing somewhere in the 3.6x range.

I actually towed 7000lbs with that Explorer once just around town cause my dads F350 was out of commission but anyway...

What would be the biggest Trans cooler I could get for this thing? What does it actually consist of to install. I couldn't find any threads on here about it, only threads on adding a second cooler to trucks that had the tow package already.

Thanks everyone
