2003 jaguar x type transmission is slipping
Bummer. Take it to a GOOD transmission shop.
If you have checked oil level and it is good then it's shop time. Unless you are a trained, qualified, well tool equipped shop, this is not a DIY project. Since it is 11 years old I would look for a used one.
Get transmission serviced first replacing all fluid with factory recommended type. If transmission still slips, take it to a respected transmission shop.
