Automatic transmission fault on vauxhall vectra r reg?

I had the same problem with a Y reg one first the basics chek and if need replace the auto transmition fluid and of problem presists google auto selection switch is sometimes gets dirty the vauxhall owners sites have this info. a good HAYNES manuel is a help.
Only the basics here but it helped me sort it and not to complex.
Give it a go not saying it will help but a good place to start.
