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 :(

you should just ask one question "what is a reliable/reputable merz workshop?"....

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

ATF and engine coolant stored in different reservoirs and uses different coolers. I can't see how the 2 get mixed. From your description, it seems more like a transmission issue.

 

If your gears don't disengage, then 'eee' sound can be worn timing belt.

Hope is the first step on the road to disappointment.

Apparently the guy from MOVA said that the engine coolant broke so mixing both up in the pipes (i dont get it?) together with spoilt radiator so we got it changed & flushed...

after flushing, from the coolant reservoir, there are still traces of oil within.. like a thin layer of brown like particles but beneath is the blue coloured coolant..

 

gears dis-engaged... like running to free gear that kind.. and car not moving when accelerator dipped...

Automatic transmission fluid and radiator can mix because there is a heat exchanger cassette that frequently corrodes. It's a thin piece of metal that separates the ATF from the radiator coolant and once that starts to leak, your ATF turns cloudy. The gearbox must be flushed.

the guy flushed our gearbox for us... but will there be still traces of oil seen inside? by replacing the radiator does it solve the problem? i dont really get what he means.....

this looks more and more serious by the moment :P if the ATF mix, then the ATF/coolant mixture would be really bad for the transmission.

 

he did mention that its quite serious... does changing the gearbox solves the problem? or more than that...

 

what a new year!

I will have to charge you sufficiently high enough for me to pay for my /////AMG and deodorant for sweaty workshop hours.

dont have a regular workshop.. just got this car 6 months ago........

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!!

Assuming the problem is really water in gearbox, then the solution is quite straightforward. There's only one way the water can mix with the ATF, and that is through a leaking radiator ATF heat exchanger.

 

You will certainly have to drain and flush the transmission case. It is highly unlikely that it needs to be entirely replaced.

 

Then, you can choose to replace or repair the existing radiator then have everything back to factory design.

 

Or, plug the leaking ATF heat exchanger and install an additional aftermarket ATF cooler. This will be the permanent solution to the problem because the ATF will be totally separated from the coolant.

 

Regarding, the high pitch sound and lack of drive to wheels, it could be a damaged torque converter. The impeller and vanes might be warped or corroded. That can be replaced with a brand new or used one but it doesn't warrant a new gearbox. 

 

If the water infiltration has been left long enough to damaged the solenoids and valves in the gearbox such that gears are unable to be selected, then it is time to get a new one.
