W210 hard down change 3rd to 2nd

[nia-ja]

Hi,
I've just had my car over a month now, a 98 E240 with 160,000km's FMSH.
Sometimes the down change from 3rd to 2nd has started to get really hard, especially if I'm coasting off throttle.Like if you were driving a manual box and just let the clutch up too fast. Sometimes it is nice and smooth so I'm suspecting electrical gremlins
I took it to a mercedes gearbox specialest to get the box serviced and its a bit better but not much....
I heard that the battery condition and alternator voltage regulator can cause problems with the box servo's or am I looking at a worn out gearbox??
Anyone got any idea's?

Nobody got any ideas??

When you say serviced was this a fluid and filter change

Fluid & filter change only

give this a try, I do not know if it will help

1. Turn the ignition key to the on (not start) position.

2. Press the gas pedal to the floor and hold for five seconds.

3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.

4. Wait at least two minutes for ECU to reset.”

Could be worth a try?

I tried that already .She's a bit sportier in gear changes but unfortunately the clunky down change is still there. The annoying thing is that its only occasionally this happens. Hot or cold temps makes no difference.

If its worse when cold then its made to hold onto the lower gear to warm up the CAT thats all I have on this

Its actually a smoother down change when cold, so I'm puzzeled really. Thanks for your advice so long!!

Give me the first 6 numbers of the VIN and I will look it up on the MB fault list a 210 ???

I have been through all of the gearbox faults and nothing listed, Maybe if you go and have any fault codes read out.

So sorry nothing else

Thanks for giving it a shot anyway!. On a norwegian MB site a guy mentioned the same problem and it was to do with a drive wheel that controls ABS and sends info to the box. This was an older 97 model W210 with the older 4 speed box so it might be different on mine. Will have to see what my local MB dealer says! Fingers crossed....

All I can re call on this is the ECU conector both ends can get poor connections and cleaning with a good swtch cleaner can help,, this is for 1998 to the end of 99 cars

It is the end CAN wires that give the trouble

Had her in for a B service today. Gearbox checked out fine. But both front bushes on the rear subframe bushes are shot. After searching the forum I found some people had a similar experience, and they were the cause of the problem. Will get a quote from the local MB guys as I dare not to try myself!
