As per title,
I can feel intermittent vibrations and when cruising at a little less than 60mph the revs rise from 1750 to approx 1950 for a second or two, vibrations can be felt, the revs then fall back and the vibes disappear.
Consumption is less than I would have hope for but as I've not driven far in this, new to me, Viano I don't know what is usual for it.
So a little research and the lock up solenoid seems to be the likely culprit, but other suggestions are more than welcome.
Is the lock up solenoid mounted on the conductor plate or is it within the TC on these?
