The issue at hand is to juddering, namely in relation to the gearbox.

I have just seen novel behavioural patterns in my W205 C200 vehicle equipped with the 722.9 gearbox. The current mileage is at 45,000 kilometres.

I see a potential increase in the perceptible roughness of the gear changes, but it is plausible that this observation may be subjective in nature.

One aspect that I find puzzling is the occurrence of a brief, subtle juddering sensation lasting around one second while the vehicle is operating at a significantly reduced velocity. This phenomenon has resemblance to the behaviour of a manual gearbox system, whereby the clutch surpasses its point of engagement by a little margin. The occurrence of the issue is sporadic and lacks a discernible pattern.

There are no codes shown on my Carly device, which leaves me uncertain about whether I should leave it as is and let it to potentially malfunction during the warranty period, or whether I should promptly address the issue.

Have you verified the level of your gearbox fluid? When was the most recent alteration made?

[Lucy_Wilson2002]

I had a similar situation in one of my electronic classes. The torque converter was successfully changed within the warranty period, resulting in the resolution of the issue.

It may be advisable to prioritise the replacement of the gearbox fluid, if it has not yet been performed. Previously, the timetable was set at 37.5k.

I have been preempted by the preceding post.

Is there a straightforward method for verifying this, or does it need complete drainage of the fluid to determine the quantity present, followed by replenishment?
Did it generate an error code?

According to the book, the recommended duration for maintenance is five years or 75,000 miles. No proof of any changes can be found in the papers. I have had the vehicle for a duration of two years, and it seems that the Mercedes dealership in Newcastle, from where I made the purchase, did not verify if the necessary maintenance had been conducted based on its current condition.

It is recommended that one own a gearbox fluid dipstick in order to ascertain the fluid levels. It is suggested to do an online search for relevant resources, as there are several instructional materials available on the subject of checking fluid levels. When doing a level check, it should provide an indicator of the condition of the fluid, including factors such as colour.

What is the age of the car? Disregarding the distance travelled. There is a lack of empirical data supporting the existence of a transmission service. Consider scheduling a gearbox service, if possible.

[Martin_Smith76]

The individual in question is nine years of age. I am unable to perceive any visual stimuli. The vehicle has a comprehensive service record from Mercedes, albeit there is no documentation on the maintenance of the gearbox fluid.

The W205 model does not include a dipstick. The vehicle has a device known as an oil dipstick.

[Megan_Wilson88]

If the gearbox is equipped with a dipstick, it may be assumed that the dipstick will provide an indication of the quantity of automatic gearbox fluid (ATF) present in the gearbox.

[Lucy_Wilson2002]

There were no discernible codes, but, the sensation experienced during acceleration resembled that of driving over a cattle grid.

[Martin_Smith76]

This is just a device used to measure the level of engine oil.

The absence of a dipstick to measure the gearbox fluid level. Further investigation has been conducted, revealing the presence of a viewing window or portal under the W205 vehicle, allowing the inspection of gearbox fluid.
A variation in sound during acceleration has been observed, occurring sporadically. The observed sensation may be described as rather abrasive, however it does not exhibit any loss of force or instability throughout the process of acceleration.
