1. When I'm going at a steady speed of 30 mph (for example) and want to accelerate gently, the revs increase for a second or two, before falling to the former level again. Sometime it happens even when I intend to stay at 30 mph without using the cruise control. It's non-reproducible, but may happen once or twice during a journey of more than 15 miles.
2. I've noticed that sometimes the car seems to crawl slower when I release the brake without pushing the accelerator.
I've booked a full service for the days to come and the gearbox oil will be changed, although it's not due yet. It has been changed in 2006 and 2010.
I've read about the solenoids, could one of these be the culprit? Any ideas, please?
Or is it about time to now ... Well, not yet.
