It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. Check the fluid level and condition, service the transmission if required and catch up engine tune up or maintenance required.

Thanx Patrick: All fluids were checked and normal. Had diagnostic check last year. How often should I get a tune up?
