unable to downshift from 4th gear to 3rd gear
 

Greetings All,
My 1997 Boxster with a 5-speed manual transmission is experiencing a problem with shifting. Specifically, I am unable to downshift from 4th gear to 3rd gear, while all other gears are functioning properly. This issue persists whether I am driving or stationary. I can successfully shift from 2nd to 3rd gear, and 3ed to 4th. but the problem arises specifically when attempting to downshift from 4th gear to 3ed.
I appreciate any insights you may have.
Thanks

Is it possible that resolving the issue is as straightforward as readjusting the cable couplers? I plan to give that a try today and will inform you of the outcomes
