My manual shift light keeps flashing when driving in my 1991 mercury capri how do ifix it?

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. First, check the Transmission Fluid level and condition, as low or dirty fluid can cause shifting issues. If the fluid is fine, consider inspecting the shift linkage and transmission sensors. If you're unable to resolve the issue, consulting a mechanic for a thorough diagnosis may be necessary.
