Why HELLA?

HELLA EC Automatic Transmission Oil Coolers' additional benefits

HELLA coolers for automatic transmissions are built for demanding thermal applications and help safeguard transmission components under load.

Thermal stability: Efficiently regulates transmission oil temperature to prevent overheating and maintain smooth shifting.

Durable construction: Withstands pressure fluctuations and heat cycles for consistent long-term performance.

System protection: Helps prevent wear on internal components by keeping fluid within the optimal temperature range.

Versatile application: Suitable for use in various transmission configurations and vehicle platforms.

These benefits contribute to improved driving performance and reduced wear—especially under high-load conditions.

How does it work?

An automatic transmission oil cooler helps manage heat generated by the transmission system to prevent overheating and performance loss.

1. Heat absorption: Picks up heat from circulating transmission fluid during vehicle operation.

2. Heat transfer: Dissipates this heat through air or coolant via integrated cooling elements.

3. Cooling cycle: The cooled fluid is recirculated into the transmission at a safe, regulated temperature.

4. Continuous regulation: This process repeats constantly to maintain optimal transmission temperature.

This constant cooling process helps ensure smoother gear changes and protects critical transmission components.

Why and when to replace?

Over time, ec automatic transmission oil cooler s can degrade due to corrosion,

contamination, or wear. Here are key signs and reasons to consider replacement:

Mechanical damage: Cracks or deformation from impact or corrosion can compromise cooling efficiency.

Overheating symptoms: Rising transmission temperatures may indicate loss of cooling performance.

Fluid contamination: Blockages or buildup can obstruct flow and reduce heat exchange capability.

Leaks: External leaks can result in fluid loss and transmission failure—replacement may be necessary.

Replacing a faulty transmission oil cooler ensures your vehicle retains safe and efficient drivetrain operation.
