Gentleman it has been few months ago when my gearbox started to do strange things. When there is a cold weather and the engine is cold after a minute of drive the engine starts to change revs quickly up and down around 1500 to 2000 revs. It seemed like the gearbox do not know what gear to drive and still changing between second and third gear or like a clutch which is sliding a bit. Something similar. But after I push the gas pedal the car pulls normally and I can drive 1000 km without any trouble.

As well SDS did not show anything. But today I was parking at home and pushed reverse gear and the car started to shake heavily - it was more less on idle but was very strange. I immediately switch off engine.

Anyone knows what is it? Clutch at the end of life? Fluid or anything more serious? Thanks for tips.

Try the simple thing first and get a fluid change. Then see..or hopefully that will be your problem.

Yea, already ordered myself to my indy to change the fluid and filter, just need to know which fluid is the best suiting solution for 320 cdi 5 speed Euro version.

I did some research and found that probably a valve body could be the cause of the problem. (I suppose that late 2004 will be equipped with behr radiator, so the leakage should not be the root-case). Do You know the part number for valve body to order?

Thanks

Milanos you should update your profile with your car year and location to help us help you in the best and quickest possible way.

And about your gearbox ... how many miles are on the car?

Cheers.

Hi will update my profile later. My car is 320 CDI inline six 12/2004 production. It is wagon airmatic equipped and currently 100000 miles on the clock.

Recently had the car scanned completely with SDS and except of one PDC sensor, all was OK.

Same problems here my friend and exactly the same car. Car is shifting very strange when it's cold...once it warms up it's ok...
I tried changing transmission oil, i even did full system flush and nothing helped...i kinda lived with this for 2 years now :)

same problem

I have had the same problem with mine, its called "gearbox stall", the rev counter goes up and down slightly when driving when the car is cold - early mornings is most common until it warms up........
Right, here we go, I had the gearbox overhauled / reconditioned / rebuilt by a specialist who had it back 3 times under guarantee, cost £1600-00 and its still doing the same....., even had a software up date done by the Merc dealer to try sort it out. New torque convertor fitted as well. Now what do we do? The gearbox man has done over 100 of these boxes, and says he has had problems with 5 of them all relating to the E320, 2004 - 2005 models, the smaller ones E220 are fine, he never has problems with the E220 after a gearbox rebuild, only the 320's. Any suggestions as even the gearbox man is confused now...???

I think its characteristic of the 722.6 when its cold. My 1997 E300D with 722.6 and my 2006 E320 with 722.6 transmission acts the same way. As far as the vibrations, you might need to replace the motor mounts.
