Transmission issue detected
 

Hello, my w220 S320 had an issue since I bought it from 1 year, while driving sometimes during drive and use brakes then accelerate the car shift down from 3 gear to 2 gear and I feel the car is shocking as like some body hit me I dont know how to explain this feeling, specially after cold start but not always else I Scan it but no codes detected and I did reset transmission it gone for while then get it back, but while driving as manual no issues at all.

I didnt try to change transmission oil since I called Mercedes exclusive dealer he told me if it is from long time that oil didn't change it may ruins the transmission at all and you will be responsible for that. So I will not do it at all.

You need to change the fluid filter conductor plate and electrical connector

you can get the parts for about $65 in eBay
just look for w220 conductor plate

Thanks a lot and hope that will fix.

thats cheap, I got OEM from ECS for about $150 last year.

I found that there was a leak since spot of fluid on the ground may this related to low fluid while I get limp mode once per two months.
How much litres transmission need?
