Hi Guys, I just bought a 1997 C280 with 5 speed auto, with 233K miles on it. The reason I bought this car is the previous owner replaced a lot of parts on it like the head gasket, timing chain, spark plugs, etc. The transmission he said was also serviced so basically I have nothing to worry including maintenance. I really like my car but this one annoying thing really bothers me, the transmission jerking when stopping that it seems somebody rear ended me. There is no check engine light and aside from that issue, the transmission shifts smoothly. I tried resetting the transmission by following the video I saw from YouTube but the jerking is still there. I also tried in both W or S and still jerks. I took this car to different Mercedes Indy shop and they gave me different advise.


1st Indy Shop: Replace the transmission with a rebuild one from 1997 or get a good used one but I might need to replace my TCM.


2nd Indy Shop: Start with updating or resetting the transmission and replace the valve body and conductor plate. He don't recommend getting an used tranny from 99 and up 722.6 tranny because it will not fit due to different shape, etc. If I will get a rebuilt 1997 to 1998, I will still have the same issue.

Now I'm planning to take it to a dealer. But before that I would like to ask your advise. Please help.

how are your engine mounts? had a similar issue on my c280, everyone jumped the gun saying it was the tranny because it was a 95 turns out it was just all the engine mounts that were completely destroyed, but everything else was service recently i was like previous owner ....

Mounts if it idles rough (or after 40k), Conductor plate for shifting issues... (Plastic transmission parts, will manufactures ever learn).

My mounts are okay. The car does not vibrate at idle even on gear. My concern now is this issue could create a new problem like the mounts.

So do you think its my conductor plate?

jerryt

My 98 the shift points would change from one trip to the next,that was the conductor plate.

Jerking sounds like a different problem.

When was the fluid and filter last changed?

The previous owner said it was like 15k miles ago. I'm getting frustrated with my car. I really love this car but this only trouble has really annoys me.
