This is my first post so excuse me if it is in the wrong area. The gearbox of my T4 1.9TD 1996 has just holed itself. (From inside) Could somebody help me decide to replace or rebuild? is this a relatively common problem? 180,0000 miles.... What sorts of things should I be looking out for and what sort of costs should I be preparing myself for? am in Bristol Bath area and would appreciate talikin it through with somebody.
