Jumpy Transmission

[oilburner]

I have a 1998 w202 c200 sport with the 5 speed auto box. It's done 110,000 miles.

After a 50 mile journey last night I drove into central London and the car started lurching as it changed into second. It also felt funny as it "changed down" (don't know how better to put that). I thought i felt something from the diff as it lurched but I assume that was an effect rather than a symptom
If I'm honest I thought the car had felt odd since I set off but nothing was obvious.
I parked up for three or four hours , cam back to the car and it was fine. No evidence of any problems.
I had the gearbox oil changed in June (probably for theh first time) and fitted a new Air Mass Meter in August.
Any ideas?

what brand was the Air Mass?

Bosch from Euro car parts

hmm well i would say that is the primary suspect, as them to swap under warranty..

You think so? It doesn't sound like transmission death then?

doubt it very much, especially as it was fine on the second attempt... typical mas death symptons

It could be an oxygen sensor also.....

Any way of checking?

Only with a diagnosic machine really as with your air mass too. Thats the proper way of checking.
