When I got my 91 auto about 3 years ago, I had the same problem. Luckily,
the PO had it fixed about 3 months prior and I took it back to the dealer
and they fixed it in about 15 minutes.  IIRC, you can flip it over and use
it longer.  I have not had the problem again in 3 years.  I believe that
others will chime in.
