About us
Why choose COOLMASTER?
We know what it takes to keep 4WDs, tow vehicles, and heavy-duty rigs running cool under pressure. Our transmission cooler kits are designed for real-world conditions – steep climbs, hot climates, heavy loads, and long-distance hauls.
COOLER RUNNING
Keep transmission temperatures in check, even under load, for smoother, more reliable performance.
REDUCED COSTS
Prevent costly transmission repairs and extend component life with effective, long-term cooling.
BETTER FUEL ECONOMY
A cooler, more efficient drivetrain reduces strain and improves fuel efficiency -especially when towing.
What People Say
We’ve fitted dozens of these in the shop – they’re consistently well-designed, complete, and reliable. No missing parts or dodgy fittings like other kits we’ve tried.

After cooking two gearboxes in my old Hilux, I finally fitted a proper cooler. This kit was easy to install and runs much cooler now even on hot days. Should’ve done it years ago.

If you’re serious about off-roading, don’t rely on factory cooling. Fitted to my BT-50, towing a van through steep terrain — trans stayed cool and no more flaring under load.
