omega gearbox problem

[allan]

Have a 2001 omega estate,2.2 auto petrol. Problem is. From a cold start,engage drive and about 50% of the time its like the gearbox is taking off in a high gear,forcing me to change manualy. After about 5 minutes,pull over and restart,the problem has gone.Went to a garage,had service etc,they said problem fixed,but after a few days it recurred. Any ideas please?many thanks. Allan.
