Mercedes-Benz W212 5G-Tronic Automatic Transmission 722.618

Product Description

Mercedes-Benz 5G-Tronic 5-speed automatic transmission, transmission type 722.618, identified with the marking 2-20-15.

The 722.618 belongs to the Mercedes-Benz 722.6 five-speed automatic transmission family, a longitudinally mounted electronically controlled automatic gearbox used across a wide range of Mercedes-Benz passenger vehicles.

Designed for smooth gear changes, reliable power transmission and comfortable driving, the 5G-Tronic system incorporates electronic transmission management and a hydraulic torque-converter system with lock-up functionality.

This unit is an excellent replacement option for vehicles equipped with the same 722.618 transmission specification, subject to confirmation of the vehicle VIN, engine, drivetrain and OE transmission number.

Compatibility Verification

Because Mercedes-Benz used multiple versions of the 722.6 transmission family, professional compatibility verification is strongly recommended before purchase or installation.

Please compare:

• Vehicle VIN
• Mercedes-Benz OE transmission number
• Transmission identification number
• Engine code
• Vehicle production year
• Drive configuration
• Electrical connector and control-unit configuration
• Existing gearbox specifications

A transmission from the same 722.6 family is not automatically interchangeable with every other 722.6 unit.

ATF & Service

Use only the Mercedes-Benz/ZF-approved transmission fluid specification applicable to the exact transmission and vehicle. Fluid capacity and service quantity depend on the gearbox variant and whether the torque converter and transmission cooler circuit are drained.

Professional installation and correct fluid-level adjustment are recommended.

Ideal For

• Mercedes-Benz W212 automatic transmission replacement
• Professional garages and transmission specialists
• Automatic gearbox repair projects
• Transmission refurbishment and rebuilding
• Automotive dismantlers and spare-parts suppliers
• OEM-specification replacement applications

Important

Please verify the complete transmission number and vehicle VIN before ordering. Mercedes-Benz produced numerous 722.6 variants with differences in internal components, electronics, ratios and vehicle applications. Compatibility should therefore be confirmed using the original gearbox number and vehicle specifications rather than the 722.6 family designation alone.
