Maybe in the future you could be more cryptic? ;)

Seriously, we know absolutely nothing about the car. Lots of things could be relevant, but you've hidden the ball very nicely.

Please take a moment to click user cp and edit details so you can easily add your vehicle and location to your profile; it's often useful information when you're seeking assistance.

So...to get more information.

How many miles on the car?
What maintenance has been done...and what has been deferred?
When is the last time the transmission was serviced? What fluid was used and who did the work?
Did this issue start all of a sudden or has it gradually been getting worse?
Have you checked for codes and if so, what were the results?
Any crash-damage history?
Any water incursion history?
Any coolant leak from the radiator tank to the transmission?
Has the pilot bushing/harness adapter plug been changed?

That's all I can think of at the moment.

Good luck.

Sorry,
I have just bought a c240 2003 from an auction in the DFW area with only 97k miles. The transmission wasn't shifting most of the time until I replaced the battery. The car started running smooth. However, when I start the car and drive it right a way, the transmission does not shif. I wait a minute or two then the car runs fine. It is cold here in Dallas and it is no excuse because my ford escort start and run in the cold. There are no codes on the mfd other than left signal light and service code A exceeded 2700 miles.
Thank you

with the c240 you really need to step on it to make go. Don't compare it to escort or accord, it's totally different animal. Make sure all maintenance issues as described in post#2 are addressed..

It does not shift despite stepping on the gas for long stretch. it just make the engine gets loud. I noticed that I have to wait a minute before driving the car and to get the engine idle at 5rpm in order for the transmission to shift.

My understanding is that the transmission is designed to do that to protect the CAT against low temp exhaust causing damage to it. My car does that too if I drive off immediately on starting in the morning on a cold day.
I may be wrong.

This is not normal behavior. I would check the transmission fluid level. Also, get it hooked up to SDS to pull codes from the TCU to see if there's anything stored.

Now I have been driving the car for a week and I thought the transmission not shifting in the cold but today i had been driving for 15 minute when mishap happened. I moved the gear to neutral and back to drive while driving. it corrected itself and it did it again 5 minutes later while I was making a curve turn. I stopped the car for few second, changed gear and back to drive....It is unpredictable

get the trans fluid checked. IT sounds like you are low on fluid. SOOOO running the trans low on fluid will/can cause internal damage to it.

also if its low on fluid you either have a leak or when a repair was performed the trans fluid was not corrected.

I will check the fluid tomorrow. Is it possible though to have low transmission fluid and no messages on the MFD other than service A exceeded 2800 miles? What do I have to check in service A?
Thank you so much.....

Very few transmission faults will illuminate the MIL. Low fluid definitely won't.

I have bought a filter, gasket, and 6 quarts of oil for the transmission today from what supposed to be a genuine European/foreign vendor Worlpac. After replacing everything, the car would not move on drive or reverse,,The transmission does not engage. standing still. Help Help please
The oil is: Dexron 111
MB 236.10

1. I doubt Dexron 111 is an approved substitute to MB fluid?
2. How many quarts did you add? Hopefully not all six quarts..
3. Are you sure you put the fluid through the transmission filler tube and not the engine oil dipstick tube?
4. are you sure you cleaned the pan and installed the filter correctly and nothing else disconected?
5. Did you replace the pilot bushing ?

Dexron is designed for General Motors transmission. I don't think you have GM transmission in your Mercedes.

You should buy transmission fluid from Mercedes dealer. Maybe your car's specifications calls for "MB 236.10" then you should check the tranny fluid bottle that says "MB 236.10". If it doesn't say, then don't use it.
