trans oil cooler

[jim-bob]

..don't know if this is correct section, but wondering if there is such a thing as a trans oil cooing radiator KIT that can be installed on a 1500 4x4 to help the tranny when towing..I'll be pulling a dual axle trailer with elec brakes with a 3000lb tractor with bucket and bush hog but not very often or long trips..I've looked at alot of used 2500 4x4's but don't want the height they all have or long whl base and probably never will "haul" any heavy loads in the bed.. Can anyone advise me..Thanks
