Ok, this is what happened several times on a 3000-km trip across Saudi Arabia. As I was driving back from Dammam on Monday, the tranny started acting weird. All was fine in D, but in M, it would behave as if it was still in D, and the 'gear number' would disappear from the dash, and it wouldn't shift. I'd have to switch off the engine and restart to get it back to normal, only for it to happen again several times on the way back. Towards the end of the trip, the problem seemed to have disappeared. Now what was that all about? Have you had that happen to you?
