Well, I, probably like you, always think there is a way out, but in this case, you have 350 kmiles on the tranny it won't go into gear, you get metal shavings during oil change. Doesn't look good at all. Probably time for a rebuilt or used tranny or another 850. The 850's are cheap, relatively easy to work on. I scored a beauty last year for 2400 bucks, that my daughter proceeded to bash up, but that's not the point. Good luck. Mike
