hi all, i'm looking at buying a 1999 zetec Td Auto 1.9 from a local dealer. The cam belt went a 1000 miles ago so theirs be a lot of work do done on the engine. it starts well and drives fine, auto box goes up and down the gears ok. But the thing is the cars done 150K, could sone one tell me what they think this box should do. Or is it at the end of its life. many thanks
