Volvo V40 T4 Auto
 

Hi.. can anyone help with a problem. I have a 1999 V40 T4 Auot and it has developed a problem with the auto box.I can start and drive for about an hour and then the auto warning light comes on and I loose power and have to stop. If I leave it for a few minutes it will start and drive again as if nothing had happened for about another hour.

Many thanks
