I have a uk 04 plaste disco. I went on a short journey and i had a problem when the disco got stuck in reverse. I called the AA and when he looked at it the problem had resolved itself and I was able to drive away. His only explanation was that in the time it had taken for him to arrive things had cooled down and sorted itself. Obviously I need to know what did cause it nad if anyone has any info or explanation please reply. Thanks.
