Bought this car, from a local dealer, last November.

Had 11,500 miles on the clock, now 13,500.

Going downhill it changes down from 7 to 4 then stays in that gear for 10 seconds or so. Sounds like it wants to change up , but doesn't.

Spoke to the dealer, last week, he drove it and said it was fine. it didn't do it while he was driving.

Gave me a load of technical stuff that I didn't understand.

What do you think?

Thank you.
