Back home in New Zealand I have a Isuzu trooper and I am trying to find out what sort of gearbox they have in them . It is a 5 speed manual . Could some one have a look on the data plate for the gearbox model , or does someone know what it is . Is it an Isuzu box or a gm box . Mine is a 2.8 turbo diesel , not that it should mater and the petrol use the same gearbox over there . I am thousands of miles away from it now otherwise I would have a look myself .
