The TV damper (throttle valve damper) is a mechanical component fitted to the automatic transmission system on the 300Tdi Defender, designed to regulate hydraulic pressure fluctuations within the gearbox valve body during gear changes. A worn or failed TV damper results in harsh, erratic shifting or transmission hunting between gears. Correct replacement with the specified unit is essential to restore precise shift quality and prevent further valve body wear.
