Secondary Transmission Cooler Kit for Mitsubishi Pajero NM-NX (2000-2021)
AUSTRALIA'S FIRST PAJERO TRANSMISSION COOLER KIT! Heavy-duty mods like bigger tyres, bull bars and towing setups all push your Pajero’s transmission harder than stock – and that means higher temps. This bolt-on secondary transmission cooler kit is designed to work alongside your factory cooler to give your gearbox the extra cooling support it needs.
It’s especially effective off-road, where the torque converter often doesn’t lock up, leading to slippage and heat build-up. Lower trans temps mean better performance, better reliability and less long-term wear.
Adding a transmission cooler is also good preventative maintenance. Excessive heat shortens the life of your transmission fluid and will shorten your transmission life.
Key features:
- Suits automatic Pajeros NM, NP, NS, NT, NW, NX (2000–2021) Tested on 3.2 Diesel. Compare photos for Petrol models.
- Works in tandem with factory transmission cooler, not a replacement
- Cools more effectively under load (towing, off-roading, big tyres etc.)
- Custom BGT4X4 stainless brackets, made in Australia
- Aluminium cooler for long life and corrosion resistance
- Complete kit – everything you need, no extra parts required
- Dimensions 288x275x20
Kit includes:
- Heavy-duty powder-coated aluminium cooler
- 3x custom stainless steel brackets (Australian-made)
- Bolts, nuts, washers, clamps
- 3/8" hose
- 3/8" barb joiner
Bull bar suitability: Will suit OEM Smart bar, ARB and MCC bull bars, and also with an Alpha 4WD bull bar if you don't have a winch.

This secondary transmission cooler kit effectively reduces transmission temperatures by approximately 8 degrees, with customers praising it as "one of the best mods." The kit features accurate mounting brackets and straightforward DIY installation. Customers noted quick shipping and high quality construction, though hose joiners need improvement.
Ordered and delivered quickly, no fuss. Fitted the BGT4X4 Cooler Kit to an MY15 Pajero Exceed and all works well. Simple installation and just followed the great little Video. No issues and highly recommended.
Thanks so much we appreciate it!
Specialist knowledge has resolve all my transmission temp issues Thanks!
You're welcome!
1) Mounting brackets were good ( Accurate & solid) Positioned the cooler core correctly.
2) Hose joiner supplied was very poor quality. Definitely needs improvement.
I used right angled barb connectors to attach the hoses to the cooler core. .Saves putting the cooler hose through a tight radius.

Thanks for the review Ticker. Please do reach out to us about what can be improved on the barb as we haven't experienced any issues so far thank you :)
They don’t mess around at BGT4x4. Ordered midday Monday and it arrived midday the next day from QLD to SA! Looks high quality and am excited to install it and see how well it performs since the Jatco transmissions in the Gen 3 Pajs like to get toasty especially since it’s only got a tiny cooler from factory with the new one nearly double the size. Definitely going to be buying more stuff from BGT4X4 in the future!
Awesome to hear Kayne enjoy! The fitment on the Gen 3 is a little different to the 4 but you will see what I mean once installed. The long bracket goed behind the bracket on the right to keep it straight and that's it cheers enjoy!
This trans cooler kept my temps way down while towing, I cannot recommend it enough for Australian conditions!
Legend thanks Alex!
HI Dee very happy with the cooler.was reasonably easy to fit and have had no issues so far. Definitely does its job as does seem to drop temps by about 8 degrees.
Hey Paul thanks for the feedback, enjoy!
Easy to DIY! Great product!
Great to hear!
Ordered as a pre-order but got it shipped out even earlier than expected! Very impressed with the quality. Glad that there are finally brackets for the Paj. Thank you Dee!!
You're welcome!
Why not have the inlet and outlets angled, so the hose fits straight on, like the original one, instead of a bend in the hose, which has the potential of cracking or splitting over time with heat and also supply enough hose, so as not to have to join old hose to new hose. Just my thoughts.
Hi Tony. We ran a smiliar setup for years and it has been fine. The cooler has brackets on the top of bottom so it cannot be mounted sideways for the hoses to go on. Trans hose is reinforced on the inside so kinking is unlikely. Just don't cut them too short and you shouldn't have any issues. We can supply longer hose however, the fitting time will just take longer for the customer hence we made it as easy and quick as possible.
Will this fit with an Ironman bullbar with a winch ?
Check out our video. If the winch cradle sits at the front of the bar then yes but if the winch cradle is bolted to the chassis then no if you have a winch.
