The 3rd - 4th change in my 190E could be a bit severe at certain revs but 2 weeks ago seemed to become smoother. Now it changes up to 4th but then "slips", ie. put your foot down, revs go up but speed builds very slowly like a slipping clutch in a manual. Can anyone tell me if there's something simple I can tighten, or is it a new gearbox job? Thanks.

I'd be checking to make sure the fluid level is not low. Furthermore I'd be checking that the auto transmission fluid had been changed within the last 36,000 miles.
After satisfying myself on those two points, if the problem persisted, I'd seek the advice of an autobox specialist who knows Mercedes boxes inside out.

Remove and plug the vacuum line to the modulator valve. This should make all the shifts rock hard. If it does, the fault is external to the gearbox. If it doesn't, you probably have a gearbox problem.

As above, check the flid level - take care to follow, pedantically, the correct procedure for this.

Also, check the adjustment and condition of the kickdown cable.
