Hey all. I was catching up on my coolant, brake, and tranny flush at the shop today.

When they were topping off my tranny fluid, they found out my tranny just would not engage. They ended up putting in too much tranny fluid and it overfilled into my engine oil. The engine started running funny and they immediately shut it off. Then, they drained the engine and put in new engine oil, Mobil 1 5w-30. I believe they did 5 quarts?

The car drives nice, now. Will I have trouble down the road because of the ATF making the engine run weird for a few seconds? They cover their work for 6months/6k miles. Is this enough time for a problem lead by this mishap to emerge?

Thanks!

WTF! This is 389 levels of f'd up.

The capacity of the sump in the C240 is well over 5 quarts.
The Mobil 1 5W-30 is NOT the correct oil for your car. It does not meet 229.5 standards. You should insist on Mobil 1 0W-40 Euro car formula because it does meet it.
They should have flushed the engine oil if it was contaminated with ATF and changed the filter. Again this would take much more than 5 quarts.
They should make damn sure the transmission fluid level is correct.

The last thing you need is another problem. Go back and insist they flush the oil out using the appropriate amounts and the correct oil. Ask to be witness to a transmission fluid check.

My indy shop would bend over backwards for me in the event they made a mistake.

Should I even be driving it? Damn!

Where did you get your service done? 5w-30 is the wrong oil.

shop = jiffy lube?

Drain your oil out and drive the car without oil and let the engine blow. Then put the oil back in there and have it towed to the shop and raise hell. I would hit a curb too and say when engine blew up I almost crashed and hire a lawyer and sue the crap out of them...they didn't put in right amount and it filled into engine?? They put you and your car in risk of danger.

A shop like that doesn't deserve to be in business.


I'm kidding..what I wrote above is just a joke...I do not promote any activities mentioned above...or do I?

Engine takes 8.5 litres - flush & change filter - Fill with correct oil.

NOW - please run by me how transmission fluid got into the engine sump??? Not by overfilling the tranny!!!! It would come out of the tranny breather.

Hahah.. DRAMA QUEEN!

Just Kidding Karo, you are alright man. Cuz

I really don't know. All I see is them panicking and starting to swap the oil in my engine. It was Zotz garage. I even recommended someone to go there. Great service, huh?

For the tranny flush, they dropped the pan and changed the filter. Four quarts or so went in. Something wrong, here, too?

c240 - motor oil - with oil filter - 7.9 US qt (7.5 l)

Trans fluid - 8.5 US qt (8.0 l)

On Owner's manual page 349. This is for 2004 Models.

Sorry don't know what year model your car. You didn't posted it in your sidebar.

5 quarts = not fully flush. Possible ATF fluid still in Engine and contamination. Since MB wants specific fuild, with ATF fluid in the system is a no no.

They should flush the Enginee oil completely to remove any possible ATF fluid. It's hard to tell how much got in and how long. Even a sec of overflow can pump in a lot of ATF fluid that may stick on the side walls inside.

Full flush is needed to ensure no contamination.

As for the ATF, I am wondering how did it get into there? Isn't this two sepearte areas? How is over flowing ATF fluid ends up inside the Enginee? Please clear my understanding on this.

I'm not even sure at this point. I think they covered up and lied. Closest the the firewall, there are to holes. I guess he poured it into the wrong hole.

04mbc230

Yup..

If that is the case, then that would be insane. They put 5 qts of ATF in the Engine and turn it up. Possible engine damage.

Oh well, better flush the engine to be sure or have them flush it and you watch. Since you are not sure what they did.

Hmmz.. I wonder if this would void the warranty. Other neglect and put in wrong fluid in engine?

They refilled the transmission fluid through the oil drain tube instead of the transmission fill/check tube and the rest is just covering up for their mistake.

laneshift

Wow! Wow!! Now what?! Is my engine done for?

04mbc230

I think I have an idea. Perhaps they thought the tube where you fill the ATF was mistaken and fill the tube that is next to it, which is the dipstick for the oil.

So they pour the ATF in the wrong tube. That must be it. Awwww.. ditto of what mleskvar said.

mleskovar

I'm guessing it will be OK. It never ran under stress with that mixture in it so I'm guessing no damage was done. Glynn knows more about the effects on seals and bearings than I do.

04mbc230

See the picture with the red tab, that is the ATF tube they should be filling it in. I guess they figured it out after turning on the ignition.

See second picture how close the oil dipstick tube and ATF tube is close by. If one doesn't know about Mercedes Engine, can easily be discourage to open ATF tube and went with the Oil Dipstick tube and thought that it is the ATF tube. Also standard doesn't comes with a dipstick, hence the more confusion that that might be the tube.

THAT IS EXACTLY WHAT HAPPENED!

What do I do now? Go to the shop bright and early tomorrow and demand they do a full oil change with a filter replacement? What about the traces of ATF in the engine atm? The shop it 5-7 miles from my house!

fookoo303

hmm makes me wonder if they even put fluid in your tranny. Seems like they might have put 5 quarts of oil in through the oil cap and 4 quarts of atf in through the oil dipstick tube, and maybe nothing into the tranny.....

That's a major f**k up.

donjuan45i

DOH...

I would be there waiting for manager to open in the morning like...Whats Good

04mbc230

That's what you need to do. Exactly what Lilbenz230 said. And of course a little of this ---> and this --->

fookoo303

lane you need to do the full oil change regardless because they didnt even put mercedes spec oil in it. They should be giving into all your requests after a foul like that. You should also have them check your atf level as you watch because it seems like they missed it.

04mbc230

Wow. That's even worst than putting the wrong fluid. Now it's running dry, definitely tranny damage on that and also contamination of ATF in the Engine. Like what fookoo said

The manager was part of the mishap. He fled during our test-drive. As did the rest of the team who didn't know what was going wrong. I am pissed.

How many years will this wipe off of my already aging w203? Sheesh!
