My GTS from 1972 has never had any service on the gearbox, other than changing oil. The gearbox spills a little oil in on the floor in the garage, not much, and I think that it howls a bit especially in 5th gear. I am therefore thinking of a service with safety wiring etc., and to have a longer 5th gear, as it revs unnecessarily much on European motorways with 4,22 differential and 0,70 5th gear. It would be easiest for me to have the work done in Europe, if there are workshops here who can do the work? Sending the gearbox e.g. to LLoyd Butfoy RBT in California would really be a long way, around 6000 miles from Copenhagen. If I must sent it to the US, the east coast would be a much shorter distance, but I don't know who is competent to do the job. All suggestions will be much appreciated, as well as - if possible - a rough idea about what it can cost.
