Registered 1997 SLK230 Kompressor
My'97 had never had a gearbox service as far as I can tell. So I had a workshop I have used for 5 years on other cars change the oil, filter and pilot bushing. Drove the 10 minutes home and found a leak under the car. Now I'm pretty sure they are not familiar with this gearbox since they didn't locate the drain in the torque convertor not did they seem to know what the pilot bushing was which is all a bit bothersome. What happens on these boxes if they are overfilled? I ask because I've been charged for 15 ltr fluid which is maybe a little over the top using a double drain,/flush.
