Transmission Oil Cooler – OEM ref 33493‑22030

Keep your automatic gearbox healthy with a dedicated ATF cooler ❄️. It lowers fluid temperature, protects clutches, and preserves smooth shifting. Ideal for daily driving, mountain roads, or towing. Cooler ATF means longer transmission life and stable performance .

Why this part is needed

Automatic gearboxes create heat. Excess heat burns fluid, causes varnish, and makes shifts harsh. A proper cooler keeps ATF in the safe zone, extending fluid and solenoid life, and preventing slip.

How it works

ATF circulates through a fin-and-tube radiator mounted in the airflow. Heat moves from hot fluid to the cooler’s core, then to passing air. Robust brazed joints and corrosion‑resistant fins ensure steady cooling at idle and speed.

What happens if it fails

• ATF overheats (burnt smell, dark color)
• Harsh or delayed shifting, possible limp mode ⚠️
• Leaks reduce pressure and can damage clutches
• Metal wear increases; early transmission failure

Install notes

Flush lines, fit new seals, follow flow direction, and torque fittings correctly. Fill with the correct ATF (WS spec),warm up, and verify level and temps. Pressure test after installation.
