we already changed a radiator.. flushed.. and the problem came back again... cld it be not a proper job done? =(

 

A computer must be plugged in to check if the transmission is able to enter into gear. If it doesn't, then the solenoids and valves might be damaged. The gearbox may need an overhaul or replacement.

 

If the transmission is able to enter into gear, then it could be torque converter problem or another problem further down stream, e.g. broken rear differential. It depends on where the sound is coming from.

 

Addition, there is a common rule that an old transmission that has never been flushed, shouldn't be flushed because it can dislodge debris and goop into the the narrow spaces and gunk up everything. In this case, because of the coolant leak, a flush is a must, the flush may have fouled things up. Especially, if the flush was not done properly with the replacement of the transmission case sump and filter.

There is but one truly serious philosophical problem and that is suicide.

i'm no mech (unlike Tanzy) but from your change description and Tanzy's latest diagram, the problem seems to be suggesting transmission slippage.

Hi...

 

I've a c200 Year 2005 on w203 engine.. Last week it decided to drop a bomb on me.. Started the engine as usual, shifted from Park to Drive, car goes as per normal but once rpm reaches 2000 & above, it started to have this loud sharp "eee" sound & eventually the gear got dis-engaged itself... tried stepping on the accelerator again and the rpm goes up but the car didnt move at all, tgt with the sharp sound again.. and the gear got dis-engaged again....

 

Brought to the workshop, the guy said that the radiator broke, causing the AT Fluid to mix with the Coolant.. so oil mix with water & water mix with oil within the car.. so we changed the radiator & flushed out the AT Fluid & also the Coolant, replacing with new ones..

 

After that, able to drive for 2 days.. but still accompanied with a mild-er kind of "eee" sound at 2000, but once reaches 3000 it went away...

 

It decided to die on me today again... same symptoms....

 

Anyone know what actually happened? Dont want to get it wrongly diagnosed again....

 

Now waiting for tow truck again :(

The previous owner must have driven the car till break down without following any maintenance schedule. Just 130k km and this problem occurs. My previous W203 ran for more than 200k km and gearbox still running soon soon.

Hmm I would advice if ur car is Agent and still able to drive send to CnC for a diagnosis check once they confirm the issue tell them u will be back on a later date and set up a appointment....if u failed to turn up that's fine...u wont be charged like that....

The world Most dangerous thing is the Vehicle. Its not about the machine weather its slow or fast. Its the person who is controlling it. The driver is the brain of the Machine. Not the machine itself.

If the driver reacts slow even the most powerful ABS(Auto braking system) will not help. The driver has to give the car the command in Order for the car to react. Afterall he is the brain of the car.

Managed to my friend's garage.. apparently he said we got chopped cuz the MOVA guy didnt flush well enough and our clutch should be dying soon. he will re-do a flushing for us... see how it goes but he dont see a need to change the gearbox.. he said the most flushing labour cost should be 100-200, but we got charged by MOVA at 500... so you know....

U use the dipstick there is a risk of oil contamination 

 

just check the side for the level if still cant find check your owners Manuel

Anyone know how to check the transmission fluid level.

There wasn't a dipstick; I assume we have to use the engine oil dipstick to check the transmission fluid. Is this so?

The 722.9 7G Tronic gearbox does not have a dipstick to check ATF level.

The only way to check level is through the drain hole via the overflow level plug. 

 

Incidentally, 2011 onwards the MB 236.14 ATF is blue coloured.

6 months ago? You can apply the Lemon law if you brought it from a dealer, hope is less than 6 months. Get it fixed by a reputable workshop, not sure which workshop u got the pm recommended by memory27. I dont have this kind of pm thingy for sure :). I dont think anyone can advise you or pin point the actual problem for you. Your only hope is to get a reputable workshop to solve yr issue. Do update us if u manage to resolve it. Good luck!!

Lemon law doesnt apply if it is due to wear and tear... And this is very subjective!
