Hi, I'm a new member her and own a 1998, C240 Elegance with 126,000 miles on the clock. Overall she's in lovely condition, but she is developing an odd gearbox problem. This is now our third car and I am two minds whether to keep it ... I absolutely love it but it may be a luxury I can no-longer afford if she becomes expensive to keep. The main symptom is its reluctance to change gear and when it does, it is fairly "clunky", nothing like the silky-smothness of her younger days. The worst fault is kickdown ... with throttle pedal to the floor, she revs to the red-line, makes a lot of noise but actually slows down! On "advice" I have changed the gearbox oil and the ABS sensors which were thought to be the cause of the problem. Clearly they were not, as this has made no difference. She is still driveable; by lifting off the throttle, revs drop, gears change up and she accelerates slowly, but overall it is a less than appealing drive. All thoughts and ideas greatly appreciated. I live in Carterton, Oxfordshire, so also any MB specialist recommendations would be useful.
