Daimler AG A0002702600 — Automatic Transmission Control Unit
Overview
Automatic transmission control unit Daimler AG A0002702600 regulates gear shifting and hydraulic pressure in 722.9 7G-Tronic seven-speed automatic gearboxes. The electronic conductor plate mounts directly onto the valve body inside the transmission oil pan, operating on a 12 V supply. It processes input signals from internal RPM sensors, oil temperature sensors, and the range selector switch. Dimensions measure 220 mm x 150 mm x 45 mm. The housing features heat-resistant composite polymer and an aluminium backing plate to seal internal circuitry against hot ATF fluids. OEM reference numbers include A0002702600, A0002701700, A000270260080, and A000270170080. The module incorporates integrated Hall sensors and electrical terminal connectors for 8 solenoid valves.
This control unit fits Mercedes-Benz models including C-Class W204, E-Class W212, S-Class W221, ML-Class W164, GL-Class X164, and CLS C219 produced between 2004 and 2015 equipped with 722.9 series transmissions. Replacement is required when fault codes P0717 or P0718 log in the ECU, RPM sensors Y3/8n1 or Y3/8n2 fail, the transmission enters limp mode, or gear changing becomes harsh and delayed. Failure stems from electronic component heat degradation, solder joint cracking due to vibration, or metallic contamination on sensor pick-ups.
