hi ,i have a mercedes w202 1995 .first it happened when i was at a stop light once, i was trying to accelerate and it would rev and not move for a few seconds then it would drive fine. it got worse and worse to the point were it would take a minute of rev to go forward and then in a period of half an hour, it wont move ,but it will go in reverse absolutly fine .

would anyone know what the problem would be ,because i have to choose weather to fix this car or my other car.??
