I'd say Prof. Sir Lou is the most qualified here to answer that, so I leave the technical aspect to him, although I think the picture shows speedo cable.
What I wanted to ask is how did you came with Polish AN-2 in your avatar?

 

Sir Kris is probably right about this.

Your car never made it to the USA so I am not really familiar with it. For the USA, the 1995 E300D was a W124 model.

It could also be the kickdown solenoid by the look of it

What is the transmission number? (What is the x in 722.x?)

 

Hi,

The car is a W210 E300 Diesel '95 made in germany, and sold in spain. I´m sorry but i don´t know what transmission i have. How can i know the transmission number????

About the An-2, it´s because a friend of mine has one.

Thanks,


Diamond

 

If you put your VIN into the VIN decoder, it will tell you the transmission number.

Mercedes-Benz Club Russia | Mercedes-Benz / VIN

Say you are in top gear and cruising. Now try to push the accelerator all the way down to see the gear kicks down.

 

That´s very useful, thanks!

Here are the details of my car:

Engine 606912 02 003161
Transmission 722438 03 884199

I´ll try what you say and i´ll let you know, but i think once i did it and yes, it changed one gear down. Why is this??

Thanks!

Then I think it is the kickdown solenoid. The wire may look damaged but it is still working.

The purpose is to accelerate faster. When it drops down a gear, the RPM will increase (for a given speed) so more power/torque is available.

 

Hi!

Sorry for the late reply, i´m busy at work out of home. Ok, then i´ll keep it like this, thanks a lot loubapache!!

Thanks!
