Why wont my BMW 740 I go in reverse ??

I own a 1993 740 I IT has 200.000 mile on her but she runs great. This past year have put over 3000 in repairs. sencers,vacume, and intake problems to get her to pass smog. Finally I got all that done . The other day when I put her in reverse I got nothing. Whats strange is all the forward gears shift smoothly like new. Is this something that is electronic, ?I know that trannys for these cars cost allot so if I need a new one well the car will be totaled. It would cost more than shes worth. I am hoping that someone out there who is a bmw expert can tell me something simple that I can do or check to solve my problem. Even if I can get the reverse to barely work I would be happy with that. I only useit to back out of my garage to leave Any ideas at all I would be willing to try the car still looks great It all Black on black leather tinted windows help!!

Hi there you don't say if its auto or manual?

If manual, I suggest you check out the selector lever, and work out just what it is doing that isn't happening with forward gears.

Hope this helps a bit.
