Keep your auto trans cool when towing
Heat is what kills automatic transmissions. A dedicated transmission cooler drops fluid temps when towing, touring or working hard — cheap insurance for an expensive gearbox, and one of the smartest upgrades for any tow vehicle.

Transmission cooler FAQs
Do I really need a transmission cooler for towing?
If you tow or carry loads regularly, yes — factory cooling is sized for average use, and trans temps climb fast under load. A cooler keeps fluid in the safe zone and extends transmission life.
Will it fit alongside my factory cooler?
Most kits are designed to add to (or upgrade) the factory cooling, not replace the radiator’s warm-up function. Our vehicle-specific kits include the right brackets and lines.
Do you fit transmission coolers?
Yes — we can supply and fit your cooler in-workshop, and do a trans service at the same time so you start fresh.
