Howdy y'all! I'm having an issue with the manual transmission on my Sephia and am hoping y'all could help. I was driving down the highway in 5th when I had to downshift for a slower car ahead of me. The transmission locked into a gear (I'm not sure if it's still in 5th or it locked after it was in 4th), but the shifter can be moved freely. Also, a few days ago it started to pop out of 5th gear of it's own accord like it wouldn't lock, and it went from every once in a while to near constantly. Eventually it got to the point where I was holding it in gear, but it would still pop every few seconds like it was trying to slip out anyway. It only would happen in 5th gear; the other gears shifted fine. Do y'all have any ideas as to what the problem may be?
