Re Transmission leak

[Ray]

I have a 2006 2500 Sprinter, with a transmission leak. The dealer said its a plactic O ring on some type of electrical pulg going into the transmission. At first look the service writter said it would be about a 45 min job and $130 repair. The mechanic said he can not get the screw out that holds the pulg in, it just turns. Now the job went to $950. and they need to change parts in side the transmisssion. I had the transmission flush at this dealership about 60 days ago. Could this have caused the current problem? Any help or advise?
Thanks

Leaks from the transmission sensor hole were a fairly common topic over the years.
Here's one example post: http://sprinter-source.com/forum/showpost.php?p=110267&postcount=1

Here's a very germane thread, with photos:

Then look at this thread, starting at message 7:

And there's always Doktor A (in Pennsylvania):

ADDED: the little set-screw is *supposed* to "just spin". It doesn't come out of its hole.
This quote is from that "germane" thread cited above:
The socket is retained by a small bronze bolt with a 7mm head. A small 1/4" drive socket and extension will easily loosen the bolt-it will not fall out-it's retained in the socket.

You might do well to PRINT abittenbinder's photo essay from that thread and bring it in to the dealer.
(Andy recommends pro-actively replacing the O-ring when a transmission refill is performed)

good luck
