    A few years back I installed, a Mag-Hytec Aluminum Finned Deep Transmission Pan, after noticing that my Transmission Temps were running around....180-190 and sometimes just over 200 Degrees, after installing it, I saw a Drop in my Transmission Temp's to around 180/190 Degrees.....But I still was Not Comfortable having my Transmission running at these number's.......even tho these number's are with-in the Temp's expressed in the Owner's Manual.........As I and Most of you guys Know the Biggest Killer of Auto Transmission's is.....HEAT!!!.

    After doing some research regarding Swapping out my Factory Trans. Cooler with a Larger Aftermarket Transmission Cooler......The Aftermarket Transmission Cooler of choice I was seeing, is the True Cool 40K Transmission Cooler.

    So after ordering not only the 40K Cooler, I ordered a EAD's Transmission Mounting Bracket Kit, which comes with New Upper and Lower Mounting Brackets for the 40k Cooler.....along with all the Mounting Bolts-n-Hardware and 2 Inverted Flair Fittings and the Compression Fitting.


    Below are some pictures of the install of the True Cool 40K Transmission Cooler

    Install of the Compression(Brass)Fitting........to be able to Spin the Passenger Side Hard-Line 180 Degrees to Line-Up/Fit onto the Threads of the 40K Cooler

    ........This past Saturday we when Boating and this was the first time Towing my Boat with the New 40K Transmission Cooler.....the Temp's were in the low to mid 90's.......the Transmission Temp's Never went over 150 Degrees!!.......about 30/40 Degrees Cooler than with the Factory Transmission Cooler......I would just say that this is without question the Best Mod I've done to help with Cooling my Transmission Temps.......

    Anyone Towing a Boat or Travel/Car Trailer....this would be a item to keep in mind for a Up-Grade......The Time it took to do the installed.......was a little over Hour......for the most part this was Plug and Play Installed, the only Mod was the cutting of the Passenger-Side Hard-lines for the Compression Fitting.

    Ya David, I was Very Pleased when seeing the Trans. Temp I mentioned, this new cooler is almost....3 Times Larger than the Factory Cooler.....after hearing/reading about other guys who have done this Cooler Swap, I felt it was worth a try.....I'm glad I did this Upgrade!!

    did you notice any difference with engine temps (going up) due to the larger area covering the radiator? Probably wouldnt due to the fans doing a good job of pulling air through the radiator but thought I'd ask.

    That was one item that I thought about David, But my Engine Temps were the same as they were before installing this larger Cooler....

    That looks like stock and works better my fav type of mod.. guess i need to take a look at one for the ram since we all know how much those trannys like heat even though i have the new 5spd auto! thanks for showing how easy is actually is!

    Nice mod and informative write up Mike, sounds worth doing even though I don't tow much.

    Well, that's very interesting to say the least. It makes sense that a larger trans cooler would do a much more effective job for cooling, I didn't think it would do that much of a difference. 90 degrees is like nice bath water, lol.

    Those are good numbers Mike. Your weather is about the same as here during boating season. How much does your boat & trailer weigh?
