Picked up a new leftover 05 Dakota Club Cab SLT w/4.7 V-8 auto two weeks ago. I installed a B&M 20768 stacked plate type tranny cooler today. SOOO easy. I tow a 3500 lb camping trailer so the extra cooling protection will be money in the pocket in the long run. I am getting just above 11 mpg towing & just under 19 mpg without towing. I've towed the camper on two different weekends now. My only complaints so far is that after taking delivery of it I found the dealer had replaced the wheels & tires for a smaller size than what is supposed to be on it. The correct tires are now on order. Nice truck.....

 

if your truck came with the heavy duty service group than the mopar tranny cooler would have come stock. or did you remove the stock tranny cooler and upgrade it to the b&m?
