    I will be pulling a trailer to the Grand this year and was wondering if a transmission cooler would be a good idea? This will be the first time pulling a trailer. I will be pulling it with a Ford F150. Any help will be appreciated.

    Thanks,
    Chad

    Your truck should have a tranny cooler built into the radiator. You may want to get a trans temp gauge on it to monitor or add an additional cooler to the current one. I have both on mine and it never heats up.

    Biggest thing is watch how often it shifts shifting is what builds excessive heat if it is staying in gear you are normally fine, but if it is constantly upshifting and downshifting it's pry getting hot.

    A B&M cooler is an excellent idea....the larger, the better. They are easy to install.

    I doubt a F150 already has one but he is right,the B & M is a good one and yes you need it. A tranny rebuild is $2500

    Depends on what kind of trailer your pulling... How heavy is it, how far is the trip? A F150 can handle a 3500-4000lb trailer all day long with out any modifications.

    Chad, my 97 and 07 both came with transmission coolers on them. If you raise the hood and look just below and in front of the radiator you will see it if it has one. I was led to belive that all 05's and newer had one on them but it may have only been those that have a towing package. You should definitely get one if it doesn't have one though. If you hit hilly country make sure you have the overdrive turned off and if pulling trailer over 60 Mph it's not a bad idea to turn it off. Jackie B.

    All Ford f150,250,350,450 etc. with automatic transmission have coolers in the radiator.

    I understand that but some have a separate cooler which looks like a small radiator or heater core. My 150's had them when I bought them. Jackie B.

    Install an auxillary cooler anyway. Hayden, B& M all ok.

    Mounts in front of cond. or rad. Internal radiator coller not enough for hauling. Good insurance. Transmissions in light duty trucks not what you call heavy duty, especially overdrives.

    I have one on my old Olds Custom Cruiser Wagon. Oil always looks like new.

    My father has a transmission shop here in South Jersey of which I have spent the last 15 years of my life at. Time and time again I have had customers come in to our shop with fairly new trucks with transmission failure due to overheating from towing even small campers or trailers. Most of these trucks had what the factory called a "tow package". I have found 2 problems that cause these overheating problems. A. Most of the newer coolers are installed inside the radiator which does not allow the fluid run under engine/ antifreeze temp. B. These coolers are way undersized and have an insufficent cooling capacity. I suggest going with the largest cooler that will fit mounted in front of your radiator, allowing the air to flow through the cooler first,thus keeping the trans fluid cooler. Hayden is fairly cheap and will work fine. Part # 14-05 is about the largest that will fit and will run you between $50-$70 depending on where you live. One last tip, make sure you run the line direct from the trans into the cooler and back into the trans direct. Some folks run the new cooler in conjunction with the factory cooler which defeats the reason of installing a new cooler in front. Good luck and any questions feel free to private message me and I'll be glad to help.

    Listen to Jason. The factory "cooler" cools into the engine coolant, adding heat into it and not cooling the transmission fluid for any kind of severe service at all. Put in a large aftermarket cooler and bypass the one in the radiator completely. That will allow the transmission to run cooler while providing a cooler reservoir of water for the engine to work out of for those times when you are pulling hills and so on. Make sure you place the new cooler where air will be forced through the fins, preferably air that isn't pre-heated from the engine compartment. If there is room, don't put it in front of the radiator because the heat from it will heat the engine coolant, but far better there than not at all.

    Buckdeerdown is absolutley correct. Larger is better. This is because cooler matrix area is a cubed function, and air flow is a squared function when you are working with heat rejection formulae. The direct line from the tranny to the cooler and back is the only way to go. Running two coolers in series only serves to decrease the efficiency of the downstream cooler.

    If you have the space, an auxilliary cooler with it's own DC driven, temp controlled fan would be the best solution. Stacking coolers front to back inhibits air flow.

    If you live in area with cold temps you may want to install a pressure bypass. No need to cool cold transmission fluid.

    If your truck has a factory tow package you have the extra cooler.

    As long as you guy's are spending his money why dont you recomend a deep sump transmission pan as well. And maybe evan a deep sump oil pan and engine oil cooler as well? As long as your at a freeflow exhaust system will help keep the engine running cooler also.
    We dont evan know what he is pulling but you make it sound like if he pulls a fiberglass canoe he will burn up his trans.

    Hmmm. F150 = 1/2 ton rating. Now then if it has a 'road' gear instead of a pulling gear even wiith a fairly light trailer you would be advised to shut dowwn overdrive most all the time. Just about every auto transmission vehicle has an internal trans cooler in the radiator, since the fifties at least and maybe before. What everone is talking about is and after market cooler or one from the factory as part of a 'tow' package. If it does not have the external cooler then $50 -75 bucks is cheap insurance and if a person can walk and chew gum at the same time you can install it yourself. Bill PS. Do yourself a favor and wash out the fins of the radiator before the trip with some dish soap and water or 'orange' cleaner. You will be amazed and the crud you will flush off it with your garden hose. Bill

    Grunt,
    Not always the case. I have seen plenty of trucks that have the " tow package " that had nothing more then a wire harness for a trailer.
    DB3006,
    I'm sorry if I came off as a know it all or as if I am spending his money for him. I was just trying to make what I feel were educated and experienced suggestions to help dissipate heat, which is the number one cause of transmission failure. If every vehicle owner installed transmission coolers, changed the fluid AND FILTER every 30,000-50,000 miles, we would be out of business.The viscosity of trans fluid breaks down just like motor oil. They are both a natural petroleum based fluid ( except for the newer synthetics )that have limitations. Again, I am only making these suggestions based on 15 years of trial and errors in this field as well as attending multiple seminars on this exact subject.
    Wireguy and Buckwheat,
    Thanks for supporting my " two cents ". Shoot straight! Jason

    Jason, All I know is that every Ford truck Ive owned has had a tow package. Just because it came with a larger radiator and the extra transmission cooler. And I dont tow anything. Nice feature helps everything run cool as you know. Dave

    Jason, What do you know about putting a Temp.Gauge on an Allison Tranny in a motorhome with a 300 cummins engine? It appears to have lots of power but I would still feel better if I could check the temp. every so often as I pull a vehicle behind. What would you suggest and how difficult would it be to put on?. Glenn

    The separate trans cooler is more effective and also will help the radiator run the engine a little cooler because it won't have to try and keep up with the engine and trans ... Not all towing packages come with separate trans coolers unless the truck is a 3/4 ton or better usually ... They are a cheap insurance policy for those who do a lot of towing and the bigger the better ... WPT ... (YAC) ...
