I drive Merc v boot sportline 6 plugs engine. I noticed recently that my car gearbox refuses to change gear. When i engaged gear the RPM will be reaching 50 to 60 while the speedmetre will be less than 40. I had noticed sometime ago that my R everve was not working but it miraculously became okay. I consulted a gearman who requested 45k to rekit it. He said that my gear box is S class version and that the fibers are weak. I dont what to do now. I was even adviced not to travel with it.

last year October i ran into a storm and the engine refused to start but it was latter pushed away. I noticed that mud water entered the gearbox oil and i went to the mechanic who after washing it with chemicals refiled it with 8 1L of Sea Horse Atf. It was fine afterward until this incedent.

The gear changing process on the w124 Mercedes is controlled by a vacuum operated modulating valve. The modulating valve is connected to a vacuum pipe from the inlet manifolds throttle head. In most cases, the vacuum pipe connections may come loose and possibly fall off leaving the modulating valve inoperative. Check underneath the car by the side of the gearbox where the valve is located and see if the vacuum pipe has come off. Secondly, trace the pipe to the inlet manifold to see if it is connected too. If everything is ok then it may be that your gearbox has internal issues which may require you bringing down the gearbox for repairs.

thank sir, it difficult to find a mechanic that we tell you that vacumm pipe has losen. They prefer rekiting to make more money.
