Transmission Leaking
Hello all,
I recently changed out my transmission fluid (pan gasket and filter replaced). I made the mistake by putting too much ATF in the tranny. I drained out about 3.5 qts and put 6qts, since the dealers recommended at service. After that I had a leak at the tranny. So I took some ATF out and measure to the correct level. The leak stop as I was driving in the local streets for a week. Yesterday I took my car on a 100 miles trip and was experiencing a bad ATF leak. There was enough fluid leak hitting the exhaust pipes caused the smoke.
I have searched and learned the the leak is common at the 2 O-rings of thedata connector plug.
I was wondering if there is any where else that the leak maybe coming from before I go underneath the car and order the parts.
Thank you
-Tom

At the dealership I was told that it is an oil pan and asked for a hunders of $ for repair, then I went to the shop that is specializing in german autos
- they changed the connector and I paid much much less.hubi

I had my transmission serviced by a dealer and after a month I saw a few drops ,
took it back to the dealer and it was the data plug.
It was $110 to check it out with out it being the transmission service and just $135 to go ahead and fix it so I spent the $25 and let them do it.
Leaking alot does not sound like the data plug.

The data plug was the only thing I didn't change out when I did my own transmission service. I wish I would have though, as it is starting to leak. Just have to find the time to get under my car and do it...

MB211 got me thinking. So I decided to to drain out the pan again and change out the gasket all new bolts. The fluid came out a bit over 4qts at the pan which a bit too much. I guess it was the combination of too much ATF and improperly torqued the pan gasket. I also change out the data plug just to be sure. So far so good but I have not make any long trip yet. I will report back once I have.

Just added over 600 miles freeway trip and it seems like everything is back to normal. I guess if I would just put the same amount of ATF back in the transmission and did not have so many beers, none of this would not happen.
