Product Overview

The automatic transmission oil cooler, OEM number A0995002300, is fitted to the Mercedes-Benz C-Class (W204), E-Class (W212), and SLK (R172), covering the 2007-2016 production run across automatic transmission-equipped models including the C180, C200, C250, E200, E250, SLK250, and SLK350. Since this cooler spans three of Mercedes-Benz's core model lines from this era, it's a high-turnover part number worth stocking in volume for distributors serving Mercedes-Benz transmission cooling parts demand.

A worn or leaking transmission oil cooler typically shows up as visible fluid leaks, low transmission fluid level, or transmission overheating and erratic shifting behavior. GSK Auto manufactures this oil cooler to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Transmission Oil Cooler?

Function: The transmission oil cooler dissipates heat from automatic transmission fluid as it circulates through the transmission system, helping maintain a safe fluid operating temperature.

Working Principle: Hot transmission fluid flows through the cooler, where heat is transferred away before the cooled fluid returns to circulate through the transmission, helping prevent overheating and fluid breakdown.

Importance: On an automatic transmission platform, a properly functioning oil cooler is essential for preventing overheating, which can lead to accelerated transmission wear or failure.

Common Failures & Signs: Visible transmission fluid leaks near the cooler housing. Low transmission fluid level from a slow leak. Transmission overheating, especially under load or in hot climates. Erratic or delayed shifting caused by overheated fluid.
