When these fail, you'll have trouble moving through gears - and the gear icon will be displayed. Troubleshooting via plug-in diagnostics should help you find which has failed, but personally I'd just change all 3 while you're in there.
Replacing this part is easy - remove the sump pan, remove the filter and you'll see the valve block. Simply use long-nose pliers to remove the securing clip, and swap the solenoids over.
3 year / 50,000 mile warranty on this part.
