Transmission oil cooler

A transmission oil cooler is a small heat exchanger that keeps automatic or manual transmission fluid within its safe temperature range, preventing overheating and the wear that follows. Fluid leaves the gearbox, passes through the cooler where it sheds heat to air or coolant, then returns to the transmission. It usually sits at the front of the car, by the radiator or built into its side tank.Most cars have one from the factory, but an extra or upgraded transmission cooler is a common addition where fluid temperatures run high:

• Longer gearbox life: Cooler fluid breaks down more slowly.
• Towing and heavy loads: A larger cooler copes with heat the standard setup can't.
• Limited gain for light use: On a car that never tows, standard cooling is usually enough.
• Fitment effort: An aftermarket transmission oil cooler needs mounting space and plumbing in.

Parthunt24 pulls used transmission oil cooler listings from marketplaces like Ovoko, ProxyParts, eBay, TotalParts, Opisto, Ecooparts, RicambiPro, and Autoparts-24. Compare 144 listings side by side on price, condition, and fitment, then click through to the seller once the right cooler appears.

What matters for fit is the specification, not how the part looks. The cooler has to match your gearbox's heat output and plumb into the existing lines, so the transmission type and code come first, then cooling capacity, hose fittings, and mounting points.An automatic transmission oil cooler is sized differently from a manual transmission oil cooler, and a radiator-integrated unit won't swap for a standalone one. Fit one with the wrong capacity or fittings and it won't shift the heat or seal the lines properly.Filter the Parthunt24 results to your make and model, and only coolers that suit your car stay listed.

• Vehicle compatibility: Make, model, year, transmission code, and OEM number.
• Transmission type: Automatic, CVT, and DCT use different coolers.
• Transmission code: Gearbox variants may need different coolers.
• Cooling capacity: Must meet the gearbox’s heat output.
• Integrated vs. standalone: Some vehicles build the cooler into the radiator.
• Hose connection type: Fitting size, thread type, and layout.
• Mounting points: Brackets and locations must match the car.
• Condition: Leaks, corrosion, bent fins, or damaged fittings.

When the original listing opens, a handful of details mark out a good cooler from a risky one.A used transmission oil cooler can hide internal blockages or weeping fittings a single photo won't show. A note confirming it flowed freely and held pressure at removal matters most, since a blocked core starves the gearbox of cooling. Run through these before you buy a transmission oil cooler:

• Photos: The core, fins, fittings, and any brackets.
• Seller reputation: Feedback score, reviews, and how long they have traded.
• Compatibility: The OEM number and transmission code confirmed for your car.
• Included components: Cooler only, or with fittings and hoses?
• Condition: Bent or blocked fins, corrosion, past leaks.
• Testing: Proof it flowed cleanly and held pressure when removed.
• Warranty and returns: A stated policy covering a damaged or mis-described cooler.
• Shipping: Fittings capped and the core boxed against crushing.

Once the details satisfy you, finish the purchase on the seller’s marketplace.

There is no single transmission oil cooler price, since it tracks the cooler type, the cooling capacity, and the brand. A used standalone unit for a common car opens at around €20-€50, larger towing coolers sit at €60-€150, and OEM radiator-integrated units push past €200.Parthunt24 lists a transmission oil cooler for sale from as little as 5.00, with every transmission oil cooler price set out together for easy comparison.What moves the transmission oil cooler price up or down:

• Type: Standalone units usually cost less than radiator-integrated ones.
• Cooling capacity: Larger, higher-row towing coolers cost more.
• Brand and condition: OEM and clean, leak-free cores take the higher price.

Putting every seller's transmission oil cooler price on a single page is the fastest way to land the best deal. Fixing a transmission cooler leak usually just means replacing the cooler or a fitting, often €50-€250 fitted, rather than a major repair.

Because the cooler sits in the cooling and fluid path, a few neighbouring parts are worth checking before installing a transmission oil cooler, since a fault in any of them undoes fresh cooling. Always fit fresh, correct-spec transmission fluid when the cooler goes on, as old fluid carries the heat damage the new cooler is meant to prevent. Check these on Parthunt24:

• Coolant radiator: Coolers often mount against or inside it.
• Radiator mount: Worn mounts let the cooler and radiator chafe.
• Radiator cooling fan: A weak fan leaves the cooler heat-soaked.
• Thermostat: A stuck one raises the temperatures the cooler fights.
• Automatic transmission: Worth checking for wear if fluid has run hot.
• Transmission fluid lines: Cracked or kinked lines starve the cooler of flow.

Hunting for a replacement or an upgrade across one breaker site after another burns hours, more so once capacity and fittings enter the picture.
