I have a 91 Integra gs Manual Shift. The Clutch was replaced about 5 months ago and today I went to shift into a lower gear and it went in but the car just reved up and didnt go anywhere. Now with the car parked I can push the clutch in and put it into every gear and let out on the clutch but it wont move an inch the motor just revs. We shut the car off and put it into gear and you can push it with the clutch out no matter what gear your in. Any help would be greatly appreciated. 
try doing a push-start to see if your clutch is grabbing. but i would suggest you check your cable clutch first to see if it hadn’t snapped yet. did you hear or feel anything out of the ordinary when the symptons you described started to appear? but when the car is shut off…your supposed to be able to put the car into gear no matter whether the clutch is out or not.
sounds like a release baring or something of that nature.
unless you somehow lost every syncro at once it is 98% likely clutch related from what your describeing
1% would probably be an axle problem
and the other 1% would be cable related as mentioned above
are there any kind of noises when you put it in gear? scrapeing while off the clutch that goes away when you depress it? grinding? etc?
No noises at all… And trying to push start it doesnt do anything its like theres nothing there like it still in neutral like theres no compression but you can start the car and it runs fine… If i could even get it to grind I would know it was the clutch but im getting nothing. I can put it into gear with the car started and not even push the clutch in and it dont do anything. But you can feel it go into gear. I’m stumped I’ve never seen anything like it.
I’m starting to think the springs on the clutch are broke and its not disengaging the clutch.
its your clutch, buy a kit and replace
i had the same problem in my EF hatch with a B16 swap, if i remember correctly the pressure plate internals exploded, put a new clutch in and she drove like new
Thought I would let everyone know it wasnt as bad as I thought. It was a Broke driverside side Cv Joint somehow it snapped completly in half with no noise or anything. When I towed it home with the truck the guy that was in the integra said he heard a thumping noise when i got home I jacked it up and it was the joint smackin up against the fender well. I appreciate everyones feedback. Thanks again
