Went in because multiple mechanics were recommending I go see a transmission specialist. For two years this tranny was slipping and stalling at stop signs, mechanic said I needed a new transmission from donor truck. Went into Benz, they spent a day analyzing the problem, checking leaks and stalling issues, as well as tough cold starts. Topped up fluids and flushed it, found the level ridiculously low. So mechanics all tried to get me to replace a tranny, that just saved me $5000, bill was $67.
