Things always happen in 3s?
So I replaced an intercooler pump already. Cut the red wires of my seat controls and spliced them into the black because my battery kept draining.
So what exactly are the symptoms of glycol contamination? I thank all these cars have that 1500-2k rpm jerk that everyone talks about, and I am not experiencing anything else unusual at the moment but I want to know exactly what to stay vigilant for. It does have a Valeo radiator, I dont really have the time or means to swap it out right now just as a precaution but I will when I am able.
What are the symptoms that would send a smart owner straight to the shop for the test. Sluggish off the line? Hesitation or jerky acceleration?

03 g35 coupe...........02 c32 Sold
i would just replace the radiator as a precaution. Its a relatively cheap part, because by the time you notice the signs, its too late.
Only way you'll really know is by doing a glycol test on your tranny fluid. I think you can get tested for around $40-60. There's a link on the w203 forum.
A behr radiator is $150 on ebay.

Local dealership charges $50 for the glycol test... I had mine tested a few months back, and now I'm already worried again. Going to get another test done here soon this week. My C32 seems to have additional vibration when I get on the throttle, but it could just be me worrying to much. I get the torque converter jerk in 1st or 2nd, but no rough shifting. Same question as the OP. What are the signs of glycol contamination other than rough shifting?

You do realize that the software that you are running in an AMG is BETTER then the base+ models, right? You'll be slowing your shifts way down doing that....

Don't be yourself. C320 software is different. Below are the C32 transmission ratios. If you have a 2002 C32, see if you can flash it with the 2003 C32 software. 2003 software is different and the SpeedShift works differently. Try that first.

MB Number: 0305453032
HW version: 47.2005
SW version: 03.2002
Diagnosis version: 2/1
Pin: 11
so i'm guessing the dealer replaced the TCU for the previous owner in '05, and it appears that the software is from '02. STAR said that their were no updates for my TCU. STAR did not have any options to flash '03 software for my car. the STAR version is 5.8.7/02/2008
why would a TCU that was made in 2005 have software from 2002?
any ideas?

I've been considering a TCU update for one main reason. After performance modifications it seems the TCU is overloaded, and doesn't know how to behave. Example... I can start to take a turn, and get the tires spinning, but the TCU believes I'm running off a cliff, and cuts full power in passive disabled mode. I'm sure the only solution is a custom tune of the system, but I've heard it's extremely expensive. I've driven in dyno mode, but it seems to have an issue with the supercharger cutting out in dyno mode. It's not an issue with IAT as it can happen right after I start the car in dyno mode.

strange thing is the MB part number of my TCU ( MB Number: 0305453032) doesn't match with either of the numbers that jerry is talking about
https://mbworld.org/forums/2046543-post76.html
The new part number is 032 545 1232. The part number in your car is most likely 030 545 2332. If you have part number 1232, then you have a 2003 or later (from what I have been told). If you have a 2002, then you need the latest TCM, which is 032 545 1232. If they says it's not for your car, reference the 2332 number and it will show in their system that it has been changed to 1232.
The EGS/ETC unit (transmission control unit) is located in the passenger front footwell under the aluminum kickplate. Pull back the carpet from above, unscrew the three plastic nuts and flip the aluminum kickplate over, and voila
Thanks to moorfan for some if this info.
It appears as if the wrecked 03 TCM that I paid $375 for was actually a new unit. I was told that these can only be programmed once and the tech at the dealership was shocked when the "wrecked 03" TCM took a reflash / re-code for my car. I brushed it off after he said it, but as I told moorfan via PM, the TCM arrived in a sealed static bag with a white mercedes sticker over it. It looked as if the bag had never been opened. The TCM itself was scratched though.
I can say that my jerk is now gone and if memory serves me right, I have over 2k on the car since I switched TCM's.

that part is diff then the software-you can have a new part running older software-sometimes the other way around too-
this is part of the reason there is only "so much" that the car can handle in mods-at some point you start to over drive the car, tranny, body, suspension, ect-
as for the jerk...I think thats just a bug in the car in general-I dont know that messing with the TCU or TCM is worth it imho-
you could try the tranny mod that Hooley posted about-larger flow rates, ect
