Any tips or advice or anything special I should look for before I change transmission fluid on my 98 e320? thank you

 

Why do you want to change it?
MB trans are ealed for life.
OK if the car has done more than 100k miles or is used under heavy operating conditions (Towing / High Ambients) may be beneficial BUT YOU MUST USE MB GENUINE TRANS FLUID (expensive).

DO NOT use usual Dextron etc or you will start to get problems. BE WARNED.
There is something special (I wish I knew what/why) about the MB fluid. Colour, viscosity, feel, smell etc are all different.

I have been havingtroubles with it and it has 135 k and I do use it a lot and I drive it very hard. Transmission has been acting up and after I aded some it has been doing better. I did get MB fluid aswell kit and it was not as bad as I expect it( little over $ 100 for all) I also got transmission dipstick for it.

 

another question....i am starting to become little boring ;-) sorry
after taking tranny oil pan out i found some metal shavings and what it looks like little bars ( about 2-3 milimeters long)and after taking filter I found some in the filter aswell....Any ideas what these are? should I be worried?

 

Oh Dear!

Your description sounds like gear teeth but this would be unusual.

If you have difficulty posting a photoi send me your email via my PM.

Hi,

Oh dear!

Looks like you have changed the trans oil OK BUT bits like in the pic should not be floating around within the trans.

It doesn't really matter where they come from something is obvious not right and to correct it will require a trans rebuil (at best).

The pic is rather small but they look somewhat like roller needles from a bearing but this is a guess.

The box does have gears in it but these gears are constantly meshed and are of a different type to a conventional manual gearbox.
Gear changes are effected (as Naz states) by application or release of brake bands which grip the epicycli gear" clusters. Asd a consequence bits of brake band debris can sometimes be found in the oil but these pieces do not fit the bill.

If I'm correct the noise you are hearing is due to the failed bearing and this will continue to deteriorate and eventually cause a major failure. The longer the bits float around and the bearing runs, the more damage will be done.

Sorry for the bad news.

Stuart.
