The shift linkage under the car is binding. You can also loosen the bolt
that gpes thru the bushings at the shifter base and lube there to correct
it. Very important not to tighten the bolt too tight or you will still have
the same prob.

I was hoping you would see my message.

I can see that I wasn't clear and you conclude that the problem was on
the clutch mechanism.
The difficulty is to move the gear stick from gear to gear, as if
there is a cable with dry lubrication.
The problem exists with or without the engine running.Consequently it
eliminates the clutch.
The car only has 80,000 miles
If there is a cable .His it accessible from the inside of the car, by
removing the center console?
Thanks

There is a cable. It does not require lubrication, but can occasionally
wear into its sheath and bind. Is pedal effort smooth and even all along
its travel? If so, the cable itself is fine.

If you're having difficulty changing gear, that strongly suggests that your
clutch is not disengaging. This can be due to either the friction disc
sticking on its splines, or a misadjusted cable.

Is gear changing easier with the engine OFF?

How many miles on the car?

Is the clutch properly adjusted? (3/4" to 1" freeplay at the pedal)

I have the feeling that there is a cable connecting the lever to the
transmission that needs lubrication.
Is there a cable? How difficulty is it to get access to it ?
Thanks
