Mine is seems fine most of the time, although I've not driven it much since it played up. The only time it seemed manifest itself, is when I got stuck in stop/start traffic, and it got very hot.
This is the second set of gear selection faults I've had with it. Last summer it started getting stuck in first gear, when pulling away. This later turned into the fault I have now. I replaced all the solenoids and the fluid in May. The box had behaved impeccably all summer, until 3 weekends ago, when I was stuck in traffic for 45 minutes. After I got out the traffic it was fine, until it just randomly went into second instead of 4th. Once it started doing it, it continued until it finally went into limp mode (F4). I've not driven it much since, as I have several vehicles at my disposal. I've decided to sell the thing now, and replace it with a 1.8 manual box FL1 instead.
