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 Isuzu D-Max Transmission Coolers here in Australia for Australian conditions.

WARNING!!  

  • 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.

Good

Great detailed instructions. Cooler fits perfectly. They need to supply next size up hose clamps as it's to hard to slide the hose onto the barbed fittings otherwise a good DIY kit.

Thanks for the review, Daniel. I will pass on your comment about the hose clamps to our tech team.

Dual Transmission oil cooler 2021 dmax

Great product, kit comes with all parts required for install, I did have to use a nut and bolt 🔩 on bottom RHS cooler bracket as there was no factory thread for the supplied M8 sems bolt to **** into 🤔. Ordered transmission oil for top up after installation which made job easier. Delivery to central Queensland 🚚 was very quick. Has given
15 to 20 *c drop in temperature 👍🏼
