Hey everyone. I recently started having a little issue with my 2002 SLK 320. When I start the car in the morning or anytime really when the engine and transmission are cold, when I start driving my car won't shift out of first. It will rev up and hold in 1st gear. When I stop, put it in park and then back into drive, the car shifts fine. It sometimes judders a tiny bit when shifting into 2nd through 5th gear but it's very subtle and it dosen't always do it. It's at random. The transmission is due for a fluid and filter change and I plan on inspecting and if need be replacing the plastic connector for the transmission control module. Anyone else had this same issue with their 2002 SLK 320 with the 722.6 transmission? I'm hoping that it's just dirty fluid and changing it out will remedy the problem. I don't have any check engine lights and there is no violent or sudden jerking or slamming into gear from the transmission. It's just that 1st gear issue.
