Toyota Fortuner and Hilux 8th Gen Transmission Cooler

What is the best automatic transmission cooler kit? It’s one that combines durability and reliability with outstanding transmission cooling. Our Toyota Fortuner and Hilux 8th Gen Transmission Cooler allows your transmission to maintain normal operating temperatures even while towing or going offroad and it is both durable and reliable as 4WD’ing in this country demands.

Add 1L Full Synthetic Transmission Fluid

When you are installing the transmission cooler you may want to top-up the transmission fluid.  Select the “Add 1L Full Synthetic Transmission Fluid” option from the drop-down menu to add 1L of Full Synthetic Transmission Fluid.

Wholesale’s transmission cooler kits are:

  • 4WD tough – Thick 3mm heavy duty steel
  • Strong single piece bracket design – For maximum rigidity even over corrugations
  • Custom designed for the Toyota Fortuner and Hilux 8th Gen
  • Dual coated – both zinc plated and Mannex Black coated for maximum corrosion resistance
  • High efficiency crossflow transmission oil cooler
  • High temp trans cooler hose and fittings
  • Full DIY installation instructions

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.

Quality product, worth the money

I came across this oil cooler when researching products on-line for my new 2020 hilux. I tow a big heavy caravan and also enjoy moderate level 4wding. I’m a mechanic by trade and have personally installed many coolers over the years of various brands and sizes. I have to admit that when I came across this cooler, I initially looked elsewhere first as it is a little on the expensive side. But after reading many positive reviews and considering the purpose fit brackets apposed to generic ones, kept coming back to this one.

I received it quick. Like only a couple of days. Packaging was good and ensures protection of the cooler. The cooler is big. I would argue one of the biggest on the market; that’s a good thing. Everything supplied in the kit is very high quality as you would expect for the price. The brackets are robust and laser cut. The instruction booklet is in colour and very detailed. I watched the You Tube video on their website which helped a lot and was a real bonus to ease of installation compared to other brand coolers. The entire installation took me about 2 hours, but I didn’t rush it and didn’t have access to a hoist so had to jack the vehicle and put vehicle on stands which killed time. The fitment is precise and professional as if it was a genuine Toyota product. The bottom bracket bolt is a bit of a challenge due to limited access but doable. I would say most anyone with some mechanical aptitude would be able to install if they have access to the right tools. I purchased one litre of transmission fluid for top-up and it was sufficient.

All-in-all a high quality product, great fitment, excellent functionality. Possibly the best cooler kit on the market that I’ve seen. Highly recommended.

Thanks for taking the time to write such a detailed review. We're glad you liked the quality of the product and were easily able to fit it yourself as a DIY.
