Looks like my preventative Glycol Contamination test came back positive. Don't have the full results yet but was told it has glycol in the transmission fluid, but not much. Looking to do the full flush and radiator replacement. Anyone have a part number or link to somewhere that might sell this part cheaper than the dealer?

Also, anyone who has had glycol contamination issues (saw some back in august), could you share what happened after the flush/radiator replacement? Any problems afterward?

You mentioned preventive. Did you think because of certain symptoms you had the radiatior checked? Were there vibrations, sounds, etc?

thnx

Transmission is fairly smooth, a bit jerky under hard acceleration but the mechanic thought it was fine when he drove it. The preventative part came from a smell that smelled like clutch but turned out to be a loose timing chain tensioner (See thread below).

you can buy a behr radiator on ebay for $150 shipped.

The transmission sucks in these cars. I had the glycol test done by the MB dealership, and I have had my transmission changed and a new tcu and a torque converter, and the car still jerks like crazy and doesnt even downshift sometimes. I ran out of options with this car. I am just driving it like it is. There is nothing more I can do to the car, and now I got a license plate light out that I cannot fix. The only thing that I am going to do to the car is change the gas pedal assembly and put in a new belt. BTW, if the transmission isnt showing signs of wear and tear after it failed the glycol test, a simple tranny fluid flush and a new upgraded (behr) radiator would do the trick. Good luck.

I think this is a common thing with our car's transmission. I have also experienced the car seeming like it is not down shifting. I did notice when I changed my intercooler pump, my transmission seemed to be more responsive.
