Oh the joys of owning a w202! Last night I went for a drive for the first time in a little while ad I noticed that the gear changes were really fierce. While it was cold it was really banging in to gear. I ignored and though it just needs a run. I stopped off to get take away and then on the way home it seemed that she was stuck in 4th gear. I tried the manual gears but nothing. Would only stay in it's gear it was in. Would still get up to motorway speed but even lockdown would not give it any power. Once I got home I turned the engine off after cursing her a few times and went indoors for a few mins. I went bcd out and took her for a spin again and bloody typical she was fine. Today on my way home from work it did it again, the gear changes were normal but I was following a car who stopped rather suddenly so I slowed right down to stop. Then as I pulled away it knocked into gear fiercely again. Then again it would stay in 4th the whole way home. I stopped and tried to select reverse but nothing. It would go to neutral but not reverse. Then it finally went in with a bang. Turned around and went back to drive but now it would only stay in 2nd gear! So again tried manual gears but nothing so kept at low speed hoping it would change but no. When I got home I noticed that she was really hot, temp gauge was really high and the res cap was starting to bubble. Only one front fan was on so I need a new one. Anyways not so worried about that as if I dont fix the other problem I'm without a car yet again! Any ideas? I thought it would just be the gearbox but why would it reset and be fine when i turn the engine off and on again?
