Descrizione
Numero di parte originale A0325451432, un originale Mercedes-Benz W211 E-Class Automatic Transmission ECU, sourced from a written-off vehicle and tested to confirm full working order before being offered for sale.
This module delivers control over the Mercedes-Benz 7G-Tronic seven-speed automatic transmission fitted to the W211 E-Class, managing slip control across the torque converter clutch and executing precisely mapped upshift and downshift events. It maintains a continuous data exchange with the engine control unit, ensuring each gear change is accompanied by a coordinated torque reduction for imperceptible ratio transitions under all driving conditions.
A faulty transmission ECU in the W211 E-Class presents as harsh or jarring gear changes that intensify under load, visible engine speed flares between upshifts where clutch packs are slow to engage, an amber gearbox warning symbol on the instrument cluster, and in more advanced cases a complete inability to progress beyond second or third gear.
This is a genuine used and tested unit with OEM part number A0325451432. Professional installation by a qualified technician is required. A transmission TCU adaptation or basic settings reset is required following installation to complete the repair and return the gearbox to normal operation.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
