Mercedes-Benz Transmission Oil Cooler Line / Pipe (inlet) 1645005572 – a used genuine OEM inlet line that also replaces 1645001672 and 1645003872. This transmission cooler pipe delivers ATF from the radiator to the transmission on 4.7L and 5.5L V8 engines found in certain GL and ML models. Symptoms of a failing inlet line include visible fluid leaks near the front of the transmission or cooler, which can cause slipping or overheating if left unchecked.
