Mercedes-Benz W176 W246 W117 Automatic Transmission Oil Cooler A2465010501 - Used Original Parts

Diagnosis and Common Symptoms

When the transmission oil cooler fails in the W176, W246, or W117 chassis, the primary concern is thermal management of the dual-clutch transmission. Common symptoms include the "Transmission Overheating" warning on the instrument cluster and the vehicle entering "Limp Mode" to protect the internal clutches. Technicians often find fault codes related to transmission fluid temperature sensors or coolant circuit irregularities. Physical indicators include external fluid leaks near the front of the vehicle or, in severe cases, internal cross-contamination where transmission fluid mixes with the engine coolant (look for a milky residue in the expansion tank). If you notice harsh shifting during high-temperature operation, the cooler's efficiency may be compromised.
