Description
OEM reference A0255450332. Genuine used, tested Mercedes-Benz W203 and W210 automatic transmission control module (TCM) — sourced from a running vehicle and inspected before listing.
The transmission control module (TCM) governs all automatic gearbox functions — gear selection based on throttle, speed and load; torque converter lockup control; adaptive shift mapping; Sport/Economy/Winter programme management; kickdown response; and limp-home protection on fault detection.
Harsh/erratic gear shifts, gearbox in limp-home mode, delayed Drive/Reverse engagement, no kickdown, transmission fault codes.
Good used condition. Verify OEM number before ordering. Professional installation is required; the TCM must have its adaptive shift values reset and may require coding to the vehicle after fitting. 14-day returns on unmodified parts.
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.
