Do I need a heavy duty transmission oil cooler?

Good question. Put simply, overheating is the number one cause of automatic transmission failure. While a few vehicle manufacturers have done a good job of building a good transmission cooling system, there are far too many that have missed the mark. Unfortunately, in some cases (typically in tradie UTE’s no auxiliary has been fitted at all; very disappointing – they should know better!). This is precisely where a heavy duty transmission oil cooler can be an absolute lifesaver for both you and your vehicle.

If you are deciding on whether your vehicle needs an external transmission cooler, consider these points:

  • There is no such thing as too much transmission cooling. Using oil coolers to help enjoy a well cooled transmission increases the life and performance of your transmission.
  • Vehicle manufacturers are looking to reduce manufacturing cost. To achieve this, some manufacturers have cut corners by removing transmission oil coolers. Others have produced compromised designs – like cooling transmission fluid by using hot radiator water!
  • There can be no doubt that all vehicles that tow or go offroad require heavy duty oil coolers.
  • Here at Wholesale Automatic Transmissions, we have solved these problems with an all Australian-made easy-to-fit complete transmission oil cooler kit.
  • Transmission oil coolers need to be mounted securely to avoid vibration and cracking. DON’T get caught out using flimsy mounting brackets or kits with multi-piece brackets. Our heavy duty Australian-made one-piece mounting system ensures your oil cooler is protected from flexing and becoming fatigued.
  • Our mounting bracket is thick 3mm steel and is both zinc plated and Mannex Black coated for maximum corrosion resistance.
  • Some cooler kits on the market today actually bolt an aluminium cooler to a stainless steel bracket. This should never be done on a vehicle exposed to dirt and water as it will create corrosion. See this article.
  • Each kit comes with highly detailed DIY installation instructions and everything you need to fit a cooler to your vehicle, including Extra Large PWR Oil Cooler, E-coated Mounting bracket, Quality Cooler Lines with Protective Shielding, Mounting Hardware and Cooler Unions if required.
  • If you have any trouble mounting your kit just give us a call. We stand behind every product we sell with excellent technical support.
  • We have over 50 dealers throughout Australia capable of doing the external oil cooler fitting for you.
