well after a bit more testing,im only getting 1st gear in D if i go in to tip mode, I can go in to 2nd,and after a bit driving it goes in to 3rd saftey mode,so gears seem to be working on the new box(sort of),so after that iv done a code test and its coming up with fault code 23 (out put speed sensor) which is next job to do i guess.
only thing that is getting me, is before i put this box in i was getting same fault,whats the chances of two gear boxes having same problem?could it be something else coursing my gear boxes to freak out up the chain? its really doing my head in now
