    What is the physical size of the Aux. cooler you guys are using? I'm thinking of upsizing mine, got the tranny a little hot yesterday. Thanks

    I have always just run the one in my Radiator. Its bigger than the stock one though. I had Performance Radiator build me a radiator. I have never overheated my tranny while 4 wheeling, or have I ever overheated my motor. My coolant temp sensor is in the head, and has never gotten over 210 on my autometer gauge in the middle of the summer with A/C on and in 4low. My tranny still looks like new.BTW the radiator is for sale if you are interested 70 obo.

    Don't know the size but I've got a Long stacked plate that almost fill one opening in my core support. After that, it goes through my monster diesel 4 core too.

    Russ, are you running a temp gage for the tranny?

    Dan, were you running a temp gage on the tranny to know what the temp was?

    That's the tricky part with auto tranny's. You can heat the fluid up, lose the lubrication properties, and not know it. It won't smell burnt, but you can definetly shorten the life of the tranny. I spent way too much time rebuilding mine to have it go south, because I'm not keeping the temp down. I want mine to lead a long and happy life, even under the extreme wear of wheelin....

    Here is a pick of mine. I do run a tranny temp guage, but it is on the return line. I run 140-160 in town & cruising, and when I run sunset point in 3rd gear with my 350 going all out to keep it at 70-75 (still accelerating a little) I get it to 190ish. After I run sunset point, I usually stop at the McDonalds at Cortes Junction to let the tranny cool down and grab a bite to eat. I don't like taking to many chances with my 700R-4, because my truck is on its 3rd tranny, so I am babying this one.

    Mines lasted for over 15,000 miles so far, and still works fine. I realize you can shorten the life of the fluid by getting it hot, but I dont think I have had that problem. I have the same setup in my burb, but with a HD 4 core rad, and the gauge is going in next week, and I tow with it so I will let you know.

    Good info Harley, Thanks. I also run the temp gage in the return line, and coming up the hill to Sunset point, I get to around 210. Looking at your cooler, it looks like the stacked plate type. I am using a tube/fin type, about the same size as yours. Maybe that is the "problem" with mine not keeping the temp down where I want it (<= 200).

    Thanks Dan. Do let me know how it works out, and all the details. That will be good info. Do you know where you are going to put the temp sender yet?

    Either in the pan, or in the test port.

    Factory option for that year was the same as the oil cooler of the same years...the nice thing is they can be had in the boneyard ...plus the core support shelf will have the dimples allready there from the factory as where to pop the holes...nice and clean.

    Mine's almost twice the size of Harley's. <a target="_blank" href=http://www.rockmodified.com/fsr/lowerterm_4-13-02/640/fsr_lowerterm0078.jpg>Here</a> is the best pic I could find already on the web. I'm on dialup in LA so I can't post anything now. Tranny cooler on the left, OEM oil cooler on the right.
