My TSX is about to hit 140k miles and I'm starting to have major transmission problems. I have had this car for the last 60k miles. The transmission fluid has been changed 3 times in that time and it has hybrid racing shifter bushings. I'm not easy on this car by any means but I have never owned anything but manual Hondas except one and it was a manual Toyota and I have never had issues with any of my trans or clutches. I always keep up with and go over an above regular maintenance. That being said this started with the fact that I can no longer put the vehicle in reverse with the engine running. It grinds every time you try to even if you double clutch before trying to engage it. Now it is becoming hard to put into any gear 1st through 6th. I find it hard to believe that I have ruined every synchro, and reverse isn't even synchronized is it? The clutch seems to grab fine with no slipping.
