Has anyone experienced this problem with there transmission, on a 5 speed automatic? I'm having problems with the gearbox on my newly acquired W210 E320. When you start the car up you can select all the gears using the Tip when stationary. It also selects fine when you start driving and will go up and down the box fine. But at about half a mile into the journey the car will get stuck in one gear. Sometimes when I’am manual selecting gears the gearbox seems to loss drive. But if you come off the throttle and then try again it will be fine. Then the box will get stuck in the one gear and when your pulling away you can feel the box slipping. If you then turn the engine off and straight on again the gearbox will select gears fine again for a bit and then gets stuck in the same gear again. The car doesn't go into limp mode or store a malfunction on the dash (trip) computer. So does anyone have any ideas what it could be? I will also get it plug into to a Mercedes fault finding machine as soon a possible. But would like to get an idea of what the problem maybe. Thanks in advance.
