== == I have an '85 that had the exact symptoms you describe. The clutches were fried in the OD unit. After a complete rebuild and approx. $2 grand I have a functioning unit. I would advise take it to someone who is familiar with the Doug Nash OD and have them run a diagnostic. Be careful because there's not alot of mechanics who know this rare set-up.

By holding the right bumper, it's the same as pushing a button or getting into a vehicle. But if it is a co-operative game then all players must be close to the terminal. Once everyone is near it someone can activate it.
