Do not shif light on?

[awojteczko]

Hello,

On our return trip from Mosport on Sunday my transmision would not
shift past second gear and the do not shift light is on. We where
close to home when this happened so I didn't have to go to far in
second gear. I checked the archives and found one post that seemed to
have a similar problem but some information is missing. If someone
knows of this problem and how to fix it, your help would be very much
appreciated.

Thanks
Andy
