You'll have trouble selling it without getting the transmission fixed, so I would recommend that you take it to a transmission specialist and at least get it assessed and quoted so you know what you're up for. I doubt that the trade would be interested in it, unless you could perhaps convince a Citroen I'm lucky enough to have unlimited access to a fully equipped workshop where I work with two post ramp, transmission jacks and air tools. To do this you need to remove everything above the gearbox including the battery tray to access the gearbox mount. You also have to remove the whole front subframe from underneath the car and also both A burning smell in a car is never a good sign, so when it comes to the gearbox, a burning smell can be the result of transmission fluid overheating. If the fluid system fails, then other parts of the system will suffer as a result. Transmission fluid acts as lubricant and a cooling agent for the moving parts of a transmission. As they are in This is a common problem on older 4HP14/18 and is caused by 'varnish' and debris on the governor. USually as the fluid warms up they free off. An automated-manual gearbox does not have a governor because all of the control data (road speed, rpm etc) is electronically sensed and the shifting of the transmission is carried out by external actuators. Hi guys, thanks for having me on this site first time I've had a Citroen only just bought it from auction got it home to find this problem.

The gearboxes no longer need to prove themselves on the solidity side, in fact, as it is not for you to manage the gear changes manually and that everything is controlled electronically and mechanically there will be no premature wear of your clutch or other components that could be strained by misuse on your part.
