    Hey guys, Stephanie with, here with a Mishimoto Performance Transmission Cooler for all 1979 and up Mustangs. A transmission cooler offers a big benefit to anyone that's done some performance mods for more power output and/or has a high stall converter. This cooler from Mishimoto is a universal application, so it'll work for any Mustang with a Mishimoto aluminum rad. When do you need a trans cooler? Well, it's safe to say that you can always just add a trans cooler. It's never gonna hurt anything as long as it's installed properly, so it won't be a source of leaks or headaches. You'll really start to need a trans cooler for your Mustang once you have a higher output of horsepower and torque. Even if you have a stock converter still, the higher output from the motor will cause a stock converter to stall higher. The higher stall will heat the fluid more than normal and cause high trans fluid temps. You're also gonna want to look into a trans cooler if you've got a high stall converter, for the same reason that I just mentioned. A higher stall means there's gonna be increased fluid forces and pressure within the torque converter, which is how the fluid temps rise. There are many benefits to keeping lower trans fluid operating temps. Cooler temps are better for the life of the transmission and to keep the balance of durability, consistency, and performance from the trans. But just like too hot is bad, so is too cool. You don't want the trans temps to be too cool either. You run into the same problems there that you do when the fluid is too hot. Consistency and lubrication. And too hot leads to fluid breakdown, and then trans failure. This trans cooler is the basic cooler design. There's no need to reinvent the wheel. It's also lightweight and has a three-eighths push-on fitting which makes for an easy install. But it'll also make it a proper sized fitting so you won't have leaking issues. It has a tube and fin design, and it has universal mounting, so you can use it for any application. As far as price, you're looking at spending under $100 for this cooler. Mishimoto does also have a heavy duty trans cooler that comes with an electric fan, if you think you need something more along those lines. And that's gonna cost about $60 more. So, I wouldn't call the install here difficult. The cooler is going to come with some items to help you mount this, like some ties, connectors, foam pads, and O-ring clamps, but you can always fob [SP] up your own way of mounting this, if you're so inclined. Since this is universal, there isn't one correct way to install this, but there are some tips I can give you to help make sure this thing isn't going to cause a ton of issues for you. You do have to be a little bit careful with the install. If it's not done properly, you're gonna be playing around with this thing a lot to fix it. You only wanna use the correct sized hose for the size fittings and lines that you're working with, and you don't want to use fuel hose. Trans fluid does have a specific hose that's rated for the pressure and chemical properties of the fluid. You also wanna make sure that you're using high quality clamps. Now, these clamps are okay, but if it were me, I would check these occasionally to make sure that they're still tight. Overall, you're looking at a two out of three wrenches on the scale, and about two hours of your time to get this installed. Wrapping things up here, this trans cooler from Mishimoto Performance is a universal application cooler that can offer some good benefits for the automatic trans Mustangs that are out there. It's gonna work to keep the trans fluid at the optimal temperatures to keep the trans properly lubricated and functioning to the best of its abilities. You can check it out more online right here at

    Protect Your Investment. Keep your Mustang's automatic transmission running cooler for better performance and a longer transmission life with a Mishimoto Transmission Cooler. Keeping your transmission fluid cool means it can do its job better and breaks down more slowly. This keeps your transmission's internals lubricated better. Better lubrication means a longer lasting, better shifting transmission.

    Perfect for Modded 'Stangs. If your Pony is making big power, your transmission needs to be able to keep its cool. Give it a helping hand with this transmission cooler.

    Use Any Mishimoto Radiator. With this Mishimoto Transmission Cooler kit, you'll also get the ability to use any Mishimoto aluminum radiator. That even includes Mishimoto radiators designed for manual-only applications.

    Application. The Mishimoto Transmission Cooler is a universal kit designed to fit all Mustangs with automatic transmissions. May require custom work for installation.

    5 Top Rated Questions

    Does this cooler allow for the use of additional transmission fluid? If so, how may more quarts could I add.

    • This cooler does not allow much more room for extra trans fluid, due to the extra line, it would be best recommended to add 1/4 quart of transmission fluid.

    Can this just mount in place of the existing factory transmission cooler? Or does that still need to be kept in place and this would just be an additional cooler? 2005 V6 Automatic.

    • This is an additional cooler and it would not be recommended to replace the existing cooler with the use of this one, it is an add on cooler to provide extra cooling for the transmission if experiencing harder driving conditions such as racing.

    Will this cooler pair with the stock radiator in my 2005 v6 auto? Or do I have to buy a Mishimoto radiator?

    • This would need to be used with a Mishimoto aluminum radiator.

    Helpful (0)

    If I purchased this... Would it also allow me to use other radiators that are designed for manual only? Or does it somehow lock you into using a Mishimoto radiator?

    • The Mishimoto Performance Transmission Cooler will allow the use of a manual trans radiator for cooling levels close to stock, or this can be used in conjunction with an automatic radiator for greater cooling by running both coolers.

    Will this work on a built c4??

    • This Mishimoto Performance Transmission Cooler is a universal fit item, and can be installed on almost any application as long as the inlet/outlet nipple in the transmission is the same diameter as the hose used in the kit.

      Transmission cooler

      This cooler works great when your stock transmission cooler can’t keep up with the temps anymore. Was seeing temps upwards of 200 degrees with stock cooler, put this one on hasn’t gone past 180 even 80 degree days

      Mishimoto transmission cooler

      The shop I took car to made a bracket that went across the new radiator and the cooler was mounted to the left side of radiator and air conditioning cooler, and that put trans. cooler in the direct air flow and left plenty of air space for the radiator. One problem was that the hose that came with the cooler would not fit on it unless a heat gun was used to soften the ends of the hoses a little then it was still kind of hard to push hose ends on cooler. I also added a mishimoto cooler with fan and a fan temp. controll module, and I have not seen temp on my aeroforce o.b.d gauges go above 175 degrees.

      Buy it!

      Dont think twice. Just buy it. Light weight and compact. Mounts anywhere you'd like. This cooler will pay itself off wether your racing or a daily driver. Extends the life of your trans regardless of its use. Mishimoto made a great product. Being its a universal cooler, you can use the supplied plastic straps or fab up your own metal supports like I did. 5 star all the way. Thanks AM.

      This helped me get my trans temps down, It was a little tricky to decide where to put this product when I first got it. The install was easy and the product did exactly what I needed it to do.
