1990 190e 2.5 16v 5sp Manual

What oil should I use in the gearbox.

How do i drain and fill?

Is there a "dipstick" of sorts?

Many thanks

Steve

PS: I did search and after reading 50+ threads STILL didnt have the answer!!!

MB recommends synthetic ATF (type A) if possible, number 000-989-26-03.

Fill plug on the right side of the trans, drain plug on the bottom. 14mm allen wrench.

Is it ATF?

Would dino ATF be okey?

When did Mercedes start putting synthetic oil in their standard transmissions?

If your access situation is similar to mine, you will need to use a pump (or similar) to fill. Good to determine this BEFORE you drain.

I have had good results with Redline MTF.

I too have had good experiences with RedLine MTL, and just changed the fluid on my daughter's 1986 190E 2.3-16, my younger son's (same car, but a Euro model) and my wife's 1988 300E with a 5 speed. The point made about having a pump to get the new lubricant into the drained transmission is a must. Once you get a suitable pump, when you do the job you need a 14 mm Allen wrench. I use a mallet to tap, sometimes pretty hard, to knock the plugs loose. Always loosen the fill plug on the passenger side of the transmission first. If you drain the fluid out and have no way to get the new stuff in, you are stuck.

I believe the transmission has an aluminum washer under the plug flanged rim. Make sure you recover it, as when the plug comes out, it can stick to the transmission and then later in the draining process get washed away. Or, buy two new ones.

The differential is the same kind of procedure. I use RedLine Shock Proof differential fluid. Seems to effectively quiet noisy rear end meshing noises and bearing noises. The plugs in the rear end are also 14 mm Allen wrench events, but only one has the Aluminum washer.

Same deal, loosen the fill line first. Don't get hung up on the fluid selection (brand, type, etc). There are many threads on the subject and for the most part, a good modern synthetic will do well in each case. The duty is different though and so rear end juice is not going to work in the tranny and tranny juice is not good for differentials. Good luck, Jim
