It's been a long time since I told you about my problem with the converter bridge. She just didn't want to shut down. So I drove for a while, but only with a ducked head in anticipation of the big bang

Last week, after just under 5,000 km without a transducer bridge, the problem has settled. Suddenly he recoups again, turns at 100 km/h only 1850 rpm instead of up to 2600 rpm, drives on my long distance in comparison to before very much more economical (clear), so needs up to 7 liters less on 100 km. Normal consumption is now again at 11 liters/100km with a BAB cut of 136 km/h. (I drive at night from 01H00 - 07H00, French highway - there is such a thing) Anyway, I am looking forward to it, but the whole leaves a bitter taste.
A small hook and a question to Hans-Jürgen:
I always had a quick jerking / vibration in the drive train on the 5000 km under half load (I told you about that on the phone). That's still noticeable now, but only until he hooks in, so at most for a second. After that, he'll be quiet. The vibrations can be compared with brake rubbing, only that it is noticeable everywhere, only not in the steering wheel (popometer).
So has the gearbox been trying to switch the converter bridge all the time? Wasn't there anything because something blocked?
I don't think it could have been an electrical defect, otherwise the "signal" that goes through the car (rubbing) would not have been registered either. Something always tried to switch.
Is it possible that a solenoid valve is filthy?
