The way I read what you described sounds to me for some reason your transmission was put into 'limp home' mode. You can do an advanced search in this forum on that term and get a better explanation.

When you turned the key off and then restarted, whatever the error was reset. If it doesn't happen again, I wouldn't worry. However if you're curious or it does happen again, the error code that put the trans into limp home is stored. It can be accessed via Star Diagnostics from the dealer or an independent garage.
