I have a 2007 tdci semi auto g/box and the torque convertor has gone broke, evidently after talking to several transmission experts they are telling me that this type of g/box was only used for 2yrs, as it had a problem, and was changed for another design. Is this true and how do i stand with fords on ths as the bill is really heavy.

I recommend you go to the gym for a few months wee man. It can't be that heavy its paper ffs!

Sounds like you have the CVT Auto Transaxle ZF
Not good boxes unfortunately
