Hi Guys, I am a new member and recently purchased an XC70 non-runner. The engine runs fine but when you select a gear the car remains as though in neutral. There is zero drive. The previous owners says he had the gearbox serviced at great cost only to fail again a few weeks later. He then bought a second hand box and that lasted just over 100km and failed. All with the same symptom.

I would really appreciate your joint experience on how to takle this problem.
To assist with my research is this the ASIN 55W-51S box?

Thanks in advance.
