Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing gearbox oil cooler will first present as a gradual increase in transmission fluid temperature, potentially leading to sluggish shifting or hesitation. If ignored, the transmission may start to slip gears, emit a burning odor, and experience significant performance degradation. Continued operation with an ineffective cooler can cause severe internal damage to the transmission, leading to costly repairs.

Installation Tip

Thoroughly flush the transmission oil lines and cooler passages to remove any debris or sludge before installing the new heat exchanger. Ensure all sealing surfaces are clean and dry before tightening the connections.

Service Note

When replacing the gearbox oil cooler, it is essential to replace the transmission fluid and filter, and to inspect the transmission oil lines for any signs of internal blockage or external damage.
