Hi guys, last year i had gear selection symptoms on my gtv that sound similar. The rotating barrel that has a large nut on the drivers end and also has a circlip on the passenger side tends to migrate right when doing aggressive gear changes and makes 3rd, 4th and in m,y case 5th hard or impossible to find. I fixed it by replacing the circlip with a hairpin style clip from the hard ware which has held strong even with lively gear changing. Just push the barel far left then replace clip. Photos may help. http://s272.photobucket.com/user/runtre ... 6.jpg.html http://s272.photobucket.com/user/runtre ... 6.jpg.html
