03 E500 transmission problem
Hello All - My 03 E500 transmision started having problems yesterday morning. I thought it would go away after restarting the motor but it didn't. On a normal acceleration, the car starts jerking back and forth before shifting to second gear. Same thing occurs from 2nd to 3rd. After 3rd, the car picks up enough speed and seems to smooth out. I also accelerated hard around 55 mph and the car starts to jerk before taking off. Another thing I noticed is that once I am cruising around 60 mph, I here and feel vibration coming from the rear, it is like when you run over the groves cut into the sides of the road so it will wake you up if you are falling asleep. I also heard a quick low pitch hum once in a while. I am taking my car into the dealer today, I just wanted to know if anyone else seen this before.
Thanks
Thanks

I have the same problem with my car. I've taken it to the dealer twice for that issue and both times they replaced the transmission control unit and its yet to correct the problem. I plan to bring it back in once more...... I will cross my fingers!!

Just a thought
they probably should change the transmission fluid and filter. As stated above if there is contamination of the transmission fluid according to the TSB this will eliminate that as a source of the problem.
How many miles on the car?

I have 39,500 miles on the car. I am pretty pissed about the whole thing. On my way to the dealer yesterday, the whole rear of the car was vibrating and making a loud grinding noise when i was going 58mph at 1900 rpm. I took it up to 60 mph and the grinding/vibration went away. Drop it back down to 58mph and accelerate very lightly, its back again. It also did the same thing at 40 mph. The service manager was seemed to be concerned about the grinding noise. He also told the rental office to extend my 3 day loaner policy from the get go. This didn't make me feel good at all.

Update
Hello All - I got a call from the dealer for an update. Bad news, unfortunately they were aware of a design flaw in the radiator that will leak the radiator fluid into a perfectly good transmission and kill the thing. If MB was aware of this defect, why did they not do a recall? The are currently replacing my radiator, transmission, and torque converter that will cost them over $10,000 to complete the repairs. This is complete BS on a brand new car with $39k miles. After countless trips to the dealer for repairs, this one takes the cake. If anyone else encounters this problem, sorry, it won't be pretty.

1) The torture knowing our trans will/may fail at any time
2) The out of service time for a week
3) Possible collateral damage occuring with a full trans replacement

I had similar problem, jerking during shifts. I took the car for service, they found traces of coolant fliud mixed with transmisison oil. They so they replaced the transmission, and flushed and replaced radiator.

Sure sorry to hear about another transmission problem with Mercedes-Benz E-Class. Particuarly a "known problem" that probably should have been addressed with a recall. My 2001 E-430 transmission went out at 32,000 miles. A transmission seal leaked fluid into the harness that powers the Transmission Control Module causing it to fail, disabling the transmission. It would go only in 1st gear. By shutting the car off, and restarting it, I was able to drive it to the dealer in "limp-home mode." It took a week to repair and the bill was $3000...luckily covered under the Extended Warranty I bought at time of purchase. I have since sold that car and bought a new Lexus LS-430. I spent enough time in the MB Garage over the past 4 years....I think I finally had enough. Best of luck with yours...I hope the repairs go well for you.

Well, worst fear came true..the dealer advised today that the transmission has glycol contamination. They will have to replace transmission, radiator, TCU and everyhting else in the path...sux..only 40k on my wifes E500.
I hope no one else has to go thru this...I don;t understand how Mercedes would let a simple radiator problem fester until it wrecks a perfectly good transmission....it must make some business sense to someone...
Has anyone written directly to MBUSA on this issue?

BTW, it took the threat of a class action suit and getting the Feds involved before anything was done about it.
I should add that my experience with BMW is that they are more likely to have design problems than Mercedes but they seem to do what they can to resolve the issues. They replaced a whole lot of V8 short blocks when they had the alusil problem. Some issues never got resolved. My 318I had a single O2 sensor on one of the exhaust manafolds. This was a severely flawed design and a Service Manager admitted it to me and told me to disconnect the O2 sensor on my car to get it to run OK. It sure messed up my fuel mileage.

It's due in soon for routine maintenance; do you know how they detected the coolant mixed with the transmission oil? Did they eyeball it or is there a more sophisticated test? I'm thinking of asking the service writer for a preventive check for coolant leaking, if that's possible. Kind of like a PSA test at an annual physical ...
edit: Like post #18, all those parts were changed at 38k miles.

But I know for sure that oil and coolant don't mix, unless MB coolant has the same elements as tranny oil.

I bought a gallon of the MB coolant at an auto parts store (Q1 03 0002), and it is light yellow in color. However, the coolant in the car's expansion tank is blue-green (more blue than green). The MB coolant I bought is made in the USA. So my conclusion is that either the coolant made in Europe is a different color, or that MB simply adds in some additional anti-corrosion chemical to the coolant at the factory which gives it the blue-green color. Would love to hear more from others who may have more info.

The M-B coolant you get in the US is made in the US to Mercedes specs. It has a low ph factor and is amber in color. I've been buying it for years and have a couple of gallons in my garage.
I don't know what Mercedes puts in at the factory nowadays.
Just a side note, never permit tap water in your cooling system or anywhere else in your car. Tap water has ruined more cooling systems than anything else. Always use a 50-50 mix of M-B coolant and distilled water.
