Holden Colorado Transmission Cooler
What is the best automatic transmission cooler kit? It’s one that combines durability and reliability with outstanding transmission cooling. Our Holden Colorado Oil 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. If you are looking for a RG colorado transmission cooler, Colorado 7 transmission cooler or a Colorado Trailblazer transmission cooler then this is the kit for you.
Here’s what our Customers are saying about our range of Transmission Cooler Kits:
“Has to be one of the best investments I’ve made. Should be fitted to all 4WD’s in Australia. Excellent instructions. Easy to fit.”
Gavin, F
“Purchased this kit for towing a caravan. Very impressed. Reduced transmission temperatures by 15 – 20°c when towing. Well put-together kit. Easy installation. Fast delivery and excellent communication.”
James, J
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 to work as a RG Colorado oil cooler, Colorado 7 oil cooler or a Trailblazer oil cooler.
- 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 Holden Colorado 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 or Transmission Lock-Up Kits.

Great Transmission Cooler Kit. I bought this on recommendations from other Colorado 4WD owners, especially when towing caravans. I enquired at my local auto transmission service centre about fitting a transmission cooler and they also recommended the kit from Wholesale Automatics. I have yet to try it out when towing but it’s performing well so far.

Colorado Trans Cooler install. Hi, the install of the Trans cooler was very easy it took approx 2-3hrs along slow and steady. The video was 100% use friendly and clear as mud. My trans temp is now sitting 10-20c cooler on average. Thanks Guys

RG Colorado Transmission Cooler. Very happy with how this has performed. Install was relatively straightforward. Before Christmas driving down the Hume Hwy, on the longer climbs on a 30deg day, I saw transmission temps as high as 97. Coming back from Vic last weekend, towing a car trailer with a car (probably 1.5T all up – small car & trailer), temps maxed out at 80 (engine temp was 97 max), mostly stayed around 75. Very happy – should have installed it years ago.

Extra cooler for my Colorado. Towing my caravan the tranny temp was around 98′ C. Now towing it is around 80′ C. I am very happy with the results. I have had the transmission oil changed after I fitted the cooler and now can tow the van with not worrying about temp.
Thanks to wholesale automatic transmission. A very well made cooler and easy to fit.

Transmission cooler. Working ok so far, test will be summer driving and towing caravan, good product
Ken Duggan (verified owner) –
Colorado trans oilcooler. Temp in transmission used to be always above engine temp by up to 12 degrees when towing, now always below engine temp. I feel much better knowing I can keep an eye on engine temp and not even worry to much about trans temp as I used to. Best mod for towing after a tow bar. Have recommended to friends easily.
