Help!

I have been reading posts on the diesel discussions for some time but finally decided to join in, in desperation. I just changed the transmission fluid filter and pan gasket. My fluid was low but could not ever detect a leak. Clean as a whistle. I put 5 L of new fluid in and crawled back underneath only to find the little devil. Near the rear of the unit is a plastic probe with a cable leading up over the top of the transmission. It looks like it bolts i right at the base of the transportation pan. A rubber boot covers a coupling in the plastic. It looks like it may be cracked. Can someone help a novice, what is this?

Should be the seal of the harness to the trans. http://catalog.peachparts.com/ShopByVehicle.epc?q=1999-Mercedes--benz-E300-Transmission&yearid=1999@@1999&makeid=63@@MERCEDES%2DBENZ@@63&modelid=6385%3AMBC%7C1572%3AED%7C814%3AFT%7C6@@E300&catid=241185@@Transmission&yearid=1999%40%401999&makeid=63%40%40MERCEDES%2DBENZ%40%4063&modelid=6385%3AMBC%7C1572%3AED%7C814%3AFT%7C6%40%40E300&catid=241185%40%40Transmission&subcatid=242913@@AT+Plug+Adapter&mode=PAI believe this is the correct part but I would want to check it to the part number below before purchasing.

Looks like this (#115, 120, 125) http://www.detali.ru/cat/oem_mb2.asp?TP=1&F=210025&M=606%2E962&GA=722%2E608&CT=GA&cat=23V&SID=27&SGR=095&SGN=09

May just need the seal rings although the selinoid has been revised a couple of times. You ought to check the harness at the solenoid and follow it up to the TCU and check again to see if any fluid has been migrating up the cable; has been known to fry the TCU.

This assuming it is actually a 99 E300....

You know you need to use only MB trans fluid only right? No Equal......And that the fill level must be adjusted using the factory dip stick tool wiht the trans fluid at 80C? It holds between 7-8L if the torque converter is also drained.

Thanks. I'll look into the parts. I bought the dipstick and the mb transmission fluid. I used a set of directions I picked up on the forum for the fluid change out. I only managed 3L when I drained it. BUT I was really low and was experiencing some slippage.

Good. After a 20 mile drive it is reasonable to assume the trans is at operating temp (unless you live in Fairbanks) and can be checked. Fill to the upper end of the 80C fill range.

Thanks Terry,

I will order the AT solenoid/ AT linkage bushing and at plug adapter and should be back in business. Think I should drive this at all while it still leaks? I use this as a work car and put about 100-200 miles a day.
