Hi,
I can't believe of the prize Rick007 mentioned. Last year an oringinal exchange automatic gearbox was 9,500 Euros at MB with 2,500 Euros refund if the old gearbox could be refurbushed, makes ca. 7,000 Euros in best case, without any workshop costs. I also spoke with several companies which are specialised to rebuild gearboxes. They all complained not to get any classic parts from MB because they built a factory to do it themselves.
