Oil Coolers from ATGL



Coolers dramatically increase the life expectancy of your transmission

When you carry small objects, like a book or a bag of groceries, you probably don't notice too much strain. It's easy to carry small things around without breaking a sweat. However, when the weight of the object increases, the act of carrying becomes more difficult. Carrying a engine or gearbox, for example, is much harder than carrying a book. Your body will need to work harder and expend more energy to carry the extra weight, and chances are you'll sweat a little in the process.

The same principles apply to our cars or van. When they're only carrying the driver, cars run easier and use less fuel. If you've packed up your car with every item from your holiday, you might notice the vehicle moving a little slower, and your fuel mileage would certainly decrease.

Whether it's our bodies or a car engine, carrying extra weight requires extra energy, and extra energy creates excess heat. The great danger in these situations is overwork and overheating. Too much heat can damage your engine, which can lead to expensive repairs or, even worse, breakdowns on the road. The same is true for your vehicle's transmission.

Sometimes the transmission fluid just isn't enough to keep everything cool. There are times when the fluid temperature can exceed the maximum range of 160 to 200 degrees.

When this happens the fluid begins to burn. This decreases the amount of fluid running through your transmission, which in turn can seriously damage all of the important moving parts within the transmission. Installing a transmission cooler is an extra precaution against overheating your transmission, and many people decide to use them in tow vehicles. Transmission coolers come in many different shapes and sizes, pulling a heavy load up a steep grade can generate a lot of heat in an engine and transmission. Will the transmission cooler be able to cool it down? There's actually quite a bit more to consider than that, but at least now you're thinking of some of the variables that you need to consider when you're choosing a transmission cooler.

Why do you need an Automatic Transmission Cooler?

  • 9 out of 10 transmission failures are caused by overheating.
  • Automatic transmission coolers can increase transmission life by decreasing transmission oil temperature.
  • Every 20 degree drop in temperature doubles transmission oil life.
  • Today's engines have been downsized for economy and must therefore work harder than before. An automatic transmission cooler can help get rid of the extra heat generated.

An automatic transmission cooler is basically a supplemental radiator that helps cool your vehicle's transmission fluid.

An automatic transmission relies on that fluid to:

  • Lubricate moving parts
  • Clean interior surfaces
  • Protect against rust
  • Transmit energy

Each year 13 million transmissions fail...90% of those are due to overheating!

By fitting a cooler you will dramatically enhance the life expectancy of your car's transmission.

Excellent service, friendly and efficient. Would recommend them to friends and family. P Baker

Good common sense service. Quick service. Would highly recommend. B Rodd

It was an absolute pleasure to find a genuine, Honest garage to deal with such as Auto-Trans in Gloucester. They sorted out a problem with the auto gearbox on my wifes MGF in a day. Nothing was too much trouble and no massive bill for unnessasary parts. All of the staff were very freindly but also very professional. After being ripped off to the tune of £500 by my local Specialist it was great to do bussiness with someone who actually knows what they are doing. brilliant service, nice people, highly recommended.
