What would cause my 1990 Maxda Miata to remain stuck in reverse? The shifter is in the neutral position, but when I let out the clutch it moves backwards. I can shift into 1st or 2nd but when I let out the clutch it stalls. It will not shift into 3rd,4th,5th, or reverse, even with the engine off. This happened as I was backing up from a store. No problems beforehand.
