Transmission Cooler Tested on Corrugated RoadsControl Your Transmission Temperature

As the largest 4WD transmission specialist in the southern hemisphere we see many failed from other less experienced retailers. It’s one of the reasons we designed and manufactured our very own Toyota Fortuner and Hilux 8th Gen Transmission Coolers here in Australia for Australian conditions.


  • Never install a multi-piece transmission cooler bracket or one that includes the transmission cooler as part of the bracket structure.  They are prone to fatigue and failure.
  • Never install a stainless steel transmission cooler bracket. Stainless steel induces corrosion in your aluminium cooler. Just google “stainless steel and aluminium” to find out more.

Wholesale is proud of our kits because they are Australian designed and manufactured for our tough, outback conditions. They won’t let you down.

Note! In order to get further control of your transmission temperature you can check out our Transmission Temperature Gauges or Transmission Lock-Up Kits.

Transmission oil cooler

Once I moved the winch forward the supplied bracket made it very easy to install the only drama was fitting the hoses to the transmission pipes while lying under the car would have been easier on a hoist. The oil temp has dropped significantly under normal load still to be tested towing . So far very happy with the cooler 👍

Thanks for the review Eric. Good to hear those transmission temps have dropped.

Ian Lloyd
Transmission oil cooler installation and effectiveness.

I installed the oil cooler because I tow a 2.6 tonne caravan. Installation was pretty straight forward and would be easier with small hands and a hoist but doable for anyone with a bit of mechanical aptitude and experience with tools.
The trans cooler does what it is supposed to do and even on long, steep climbs with the van in tow the temp is stable around 90-95 deg C.
Worth the money.

Thanks for the review Ian. Glad that the cooler is controlling your transmission temperatures.

Great kit.

Great kit fast delivery. Someone does need to check the kit has everything in the box prior to shipping as I was missing the cooler hoses. I did ring and they were very quick to send out the hoses for me so thank you.

Hi Matthew, thanks for the review. Sorry about the missing cooler hoses - I'm glad we were able to fix this up quickly for you.
