2006–2007 Mercedes-Benz E350 4MATIC (Sedan & Wagon)
Note: This unit is for the 5-speed 722.6 transmission found in 4MATIC models. It will not fit Rear-Wheel Drive (RWD) models equipped with the 7-speed 722.9 transmission. Always match part number 035 545 04 32.
⚙️ Features & Benefits
Genuine Mercedes Part: Ensures the precise shifting characteristics and fuel economy intended by the factory.
Plug-and-Play (mostly): Unlike the later 7-speed units, these 5-speed TCUs are generally not "theft-relevant," but may require coding to match your vehicle's specific axle ratio.
🔩 Installation Notes
Located in the passenger side footwell (under the carpet, behind the metal kickplate).
Crucial Tip: If your old unit failed due to oil contamination, you must replace your transmission 13-pin connector plug/bushing and clean the wiring harness, or oil will wick into this new unit and destroy it.
