2003 C230 transmission problem
Loud whining sound after got off freeway. Louder as I drive faster.
engine oil & trans oil level ok and recently changed.
I was trying to make it back to my mechanics via streets. All of sudden, CEL on and feels like in neutral. Tow it back to my mechanics. I was able to drive it into his shop. I guess I can drive it for short distance.
Codes are
P2600 - circuit 87 voltage too low
P2315 - cam communication
P2502 - gear implausible or transmission slipping
Any suggestion?

I had the famous Valeo radiator problem in Dec 2014. Coolant and transmission fluid got mixed about two months ago. Bilstein was used.

Was it this fluid?

Just want to make sure they put the approved stuff in. Was the level checked properly?
If you want to save some money on the rebuild get a case of Shell 134 ATF from your local shell distributor its usually around $60 for a 12 pack so much cheaper than anything else I have seen by a lot. And yes it is 236.14 Approved so it works in the 722.6 and 722.9!
How was the car right after the radiator was replaced and trans fluid was flushed?

Fuchs Titan ATF-4134 is what Mercedes-Benz put in at the factory.
Febi Bilstein ATF 134 is what Mercedes-Benz sell at dealership (look closely at plastic bottle, same Febi Bilstein bottle just with Mercedes-Benz label,... and price!)
Without seeing your car, it sounds like there was way too much transmission oil put in. As a result, when it heated up during highway driving it expands but there's not enough air in the system to absorb the expanding transmission oil and pressure,... so it damage the pump and any seals.

Yes, that is the fluid that was put in. I would assume the level was correct. The car ran fine after the new radiator and transmission fluid flush.
humm...I can't prove if too much fluid was put in last Dec. I trust the shop and the guy doing it. I would think he did not put in too much.

Look at your invoice to see how much transmission fluid they put back-in in December when they did the partial transmission change. It generally drains about 3-4L from drain pan. Did they put bak 3-4L or did they put back 8L listed as capacity. Also, when they measure transmission oil level with dipstick,.. there's a kink in the car's dipstick tube that the dipstick needs to be forced through,... if not, you'll get too much transmission oil.

According to the manual, transmission oil is MB 001 989 21 03 10
https://bevo.mercedes-benz.com/bevol...236.10_en.html
which is 236.10
But when I got to Pelican.com it says 236.14.
236.10 and 236.14 uses different transmission fluid.
Which is right?
