If the manual shift light on your 1991 Mercury Capri is flashing, it may indicate that the transmission is not shifting properly or that you're operating in a gear that isn't optimal for your speed.

If you're unable to resolve the issue, consulting a mechanic for a thorough diagnosis may be necessary.
