Help! Leaking Tranny
 

I have a 92 400e with less than 100k miles. It has a major leak coming out of the left side (driver side)of the pan. I wonder what others may have experienced and how hard a fix this is? Lee Myles transmission shop is calling this a switch (??) and claims once it is fixed the leak will stop. Anything else you guys think I should do now that it is in the tranny shop (that's not too expensive) I would appreciate knowing.
Most grateful for advice, Sally

I have a couple of tips for you...
 

Do a search under "transmission leak" on the top right of this page. You will find a lot of information. It sounds like something simple, where the transmission does not have to come down.
Second, get somebody that specializes in MB's. It does not have to be the MB dealership. Trust me, it will cost you less in the long run.
Good luck and welcome to the forum.

On the left side of that trans there are a number of easily repaired leaks. There is a shift pressure switch toward the front that works with the shift overpressure control system. There is a reaction valve for a band, the modulator, the secondary pump/governor towards the rear.

Having experience with the tranny is important and many transmission shops should have it. If they have made an external leak diagnosis they probably know how to deal with it. If it is the pressure switch, there is not much they can do wrong except misdiagnose it.
