Shifting Issues

My car:2010 LGT 167,000 miles. I know there can be issues in shifting caused by a bad clutch or the pedal not allowing for the clutch to go all the way out. I ran into a different issue where my car will not shift into 5th or 6th, as if it was locked out like reverse. I did not do anything harsh to those gears recently and it just happened when driving after starting it up and accelerating to 5th at average speed. please help. what issues may other people also encounter after the amount of years there legacy gt has been on the road.

Someone likely pushed over the reverse lock out stop. You will need to pop off the shifter trim and use a screw driver to loosen and readjust the stop.It happen to my car when it was transported.

That was exactly what was wrong. I popped off the cover from the top and immediately saw that the bottom bolt on the stop was loose. I just readjusted and re tightened. Maybe i should put thread locker on? So I overshot 5th and 6th every time. haha I drove like 15 miles not knowing that I could use the gears. Thanks so much!
