So before I bring it to a shop I want some opinions. I tried searching the internet and couldn't rlly find the same problems. About 2 months ago my low mileage (80k) 320 started a weird jerk. I narrowed it down to it doing it when I get on the highway at around 60-70 and after about 10 seconds it will jerk and make a vacuum like suck noise very quickly. It will do it off the highway too I usually justdon't get that fast. Now I tested it and it won't do it again unless I shut the car off. I got off an exit and back on the highway and had no problem. Then got off. Shut the car off and back on then back on the highway and it did it again. Sometimes it's harsh sometimes not so much. Kind of feels like a hard shift but the car is already in 5th. Then last week it started a small stutter as well when I'm at a stand still for a few minutes then accelerate. Almost like a maf stutter. Then last night I was at a light waiting to make a u turn. It turned green I hit the gas and the Car creeped and revved high as if I was in neutral.put it in park and back in drive and it was in kind if a limp mode but I had no warning lights. Then same thing tonight but I imidiatly killed the car and restarted it and it drove fine. Besides this the car drives strong and powerful. I want to bring it in this week due to the fact of it not moving after I and stopped as that's kind of a problem. Just wondering if anyone here has any ideas. It's in great shape and it's got low miles so I'm not sure what it could bE. I so know its never had a tranny flush. Doubt that would fix it though.

Sorry for the massive post

Update for anyone with problems like these. Had my mechanic check the fluid and it was 3 quarts low. It was also leaking from the plug on the torque converter. Replaced the part and did a tranny flush. Don't know why I didn't think of this before because I did this on my 02 c320. It fixed all the problems

Probably the electrical connector. The o rings leak on them. Cheap fix. jeep uses a similar Mercedes transmission on their 2005-2010 grand Cherokees and they have the exact same problem. I've replaced it on my Jeep and my E320

Yea they replaced the whole connector and rings. I did the same thing last year to my c320 so I'm not sure why I didn't think of that in the first place

I was in a repair shop that specializes in Mercedes and he had a whole drawer full of them. Replaced it whenever he does transmission service
