Read through this site http://www.ashcroft-transmissions.co.uk/faq.html to see if you see a symptom match. If you do, you will see a fault explanation. Ashcroft is in the UK, but they are experts with the ZF.
You will essentially have three transmission options (from most-to-least expensive):
1. New
2. Rebuilt
3. Used
If you have a good, ZF-competent shop near you, the rebuild might be a good option, but IMHO generic rebuilds are questionable (what exactly did they do?). So locating a good, low-mileage, used transmission quickly becomes the desired option. That's what I decided to do. If you're handy with a wrench and work on your rover, you can do the swap yourself saving a lot of money. If you go down that road I can give you some pointers from when I swapped my ZF...
Regards,
