03 E500 transmission problem

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?
This basically sums it up:

Ck. out post #12. MB recognized the problem: If your car (C32) has a production date of Sep. 03 (ck. exact date in that post), AND a Valeo radiator, AND identify the crimps to be as stated in post #12, chances are the rad. is or will leak coolant into the tranny, causing glycol contamination.
MB rectified the problem by replacing the Valeo with BEHR radiators, or used a better quality Valeo (the rad. top end crimping is diff. from the "bad" Valeo).
SO, reading this thread and MB confirming glycol contamination gives me evidence to presume the pre-09/03 E500's (maybe E320's too?) use the same or very similar defective radiator that can be found in the C32.
I could be wrong, but the evidence is compelling.....
Good luck with the fix.
For those that meet this criteria, you can ask MB to perform a glycol contamination test. I was interested in the C32 before my E500 purchase, but opted for the E due to space requirements. I never followed up if MB will pay for the damage....I hope they do!
Oops, I just noticed how old this thread is, but its good info. and RONB, hope this helps a little. There is a way to identify if you have the BEHR or Valeo, but again search the C32 forum to find out how to ck. it. (The brand is not stamped on top of the radiator in plain sight).
Does anyone have a part number on the current & replacement rads? I'd like to see if my car has been updated. If not, I'm thinking of changing the rad. Any thoughts? I don't see it being any where near as expensive as an new tranny.
Thanks...

I have a C32 2002 with no issues (jerking or otherwise) and want to prevent the problem before I have it. I would appreciate if you could either copy-past the DTB here or email to me. Thanks, Andy
I contacted my local dealer, decribed my problem to them, and also let them know about the TSB. They claimed they have never heard of a glycol contamination problem with the E class. Fearing the worst of glycol contamination (as I have no warranty) I took a gamble to see If I could fix the problem myself.
This is what I did. I disconected the transmission lines where they entered the radiator and installed a Mr. Transmission trany cooler in the area behind the fog light ( bypassing the stock transmission cooler in the radiator)Took my benz to the dealer and had them do a complete flush of the transmission.
NO MORE JERKING/ SHUTTERING etc...
If cought early enough, I guess no transmission damage should occur with glycol contamination, and if my tranny never had glycol contamination(as a test was never performed) I made sure it would never happen,as my ride has the Valeo radiator. This is a cheap way to prevent a potentialy very expensive repair bill.
DISCOVERED NEW INFORMATION THAT ANSWERS MY OWN QUESTION!!!
I just read the MB pamphlet on Certified Pre-Owned (CPO) Extended Warranties. I now realize that MB provides an automatic 12 months CPO warranty, up to 100,000 miles max, when you buy a Certified Pre-Owned vehicle from a MB Dealer. In my case, I also bought when I purchased my CPO vehicle from the MB Dealer an additional 24 months CPO Warranty which also is still limited to the max 100,000 mileage. So, MB provides the option when you buy a CPO vehicle a max coverage of seven years not to exceed 100,000. I now realize I have another year of MB warranty coverage and I don't have to worry about buying a third-party warranty from Warranty Direct until Jan 2010.

Long story short, I'm out 3 grand and my car won't be ready till Wednesday. As soon as I get out of law school I'm buying a Lexus. Even my 330ci didn't have problems this expensive by any stretch. Sure it nickeled and dimed me once in a while but a hundred bucks at the worst. I'm really disappointed in this car as of late. The handling is great and the ride is nice but this problem along with some finnicky electrical/ECU issues I also had recently really makes me wish I still have my BMW. Best of luck to everyone else.
