My 2008 Honda civic 5 speed manual transmission will not go into reverse. This is a common problem apparently and the car has always been difficult to get in reverse but recently the problem seems to have gotten worse. Reverse is popping out of gear, grinding and popping and this morning when I put it in reverse I felt it engage but the car would not move. I know the tranny is not syncro'd and I tried shifting it through the gears then to reverse but it is not cooperating at all any ideas please help the car has 70000 miles on it and I've never had anyother issues.

Have them flush the fluid out under warranty and put in new fluid, and have them bleed the clutch lines in case air is getting in there. Audi and VW claim lifetime transmission fluid but it's BS - I've changed relatively low mile fluid from these cars and it was horrendous. It's possible that the fluid itself is causing trouble, but it's more likely that it is a synchro problem. If it was a clutch issue, you should have problems with more than just reverse gear - a clutch simply engages and disengages the engine and transmission, regardless of which gear it is. The problem (if not fixed by fluid) is in the transmission, and being under warranty, don't accept another "suggestion" like they're giving you. Changing your clutch isn't gonna do it.

I asked a Honda repair technician and he said that it sounds like the throw out bearing and due to it's location, we are looking at a $1,500 repair.

For a manual transmission, if you open the hood and look to the left of the engine on the side near the bottom of the engine compartment, you will see a large nut that, if removed, is where you put your gear oil, but that did not help me. If you have an manual, look up gear oil and there will be a diagram.

Are you sure that it is gone? make sure the all the bushing on the transmission are good it maybe that it is not able to go all the way in gear. If you do need to take it out get a good manual "Bentley" are the best it will show you the inside of the transmission too. Haynes are also good but not for working on the transmission it self

SOURCE: gear shift won't move out of park sometimes

look for transmission shift interlock solenoid fuse.or a bad brake switch will cause transmission not to come out of park.
