Heyo everyone.

So my 1995 e300d has been shifting roughly. vacuum checked the modulator and found it does not hold vacuum.. pulled it out to get the part number

part number is 126 270 5979... CAN'T FIND REPLACEMENT

Called mercedes, they had a hard time finding any info. they told me there are two other compatible part numbers. 126.270.2779 and 126.270.9379

I am able to find 9379 online for sale, but it says it's for a 190d.

I'm confused and dizzy from looking as I've spent about 2 hours looking and trying to find which ones will work for my car.

Please help if you can or have experience..

the vacuum modulator I pulled is a dull red/orange
