Believed to be around a 70's trans, maybe out of a fastback. engine #U50. Its in a trike I just bought. Any thoughts about all the air canisters, relays, vacuum pots? Has a little switch on the shift handle going to a relay. Do I need it all on this thing? I've built a couple or so VW trikes but I never had one of these auto shift trans before and know nothing about them. Thank You.
