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 Hilux 7th 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 cooler

Running this cooler in a 2009 hilux 4 speed auto GVM upgraded to 3300kg with a slide on camper. Never see the temp above 90°C. I like to confirm what the gauge reads with a temp sensor gun onto the hotline union coming out of the transmission. Easy install, very happy with the product.

Glad that you're happy with the product Chris. Thanks for the review.
