The transmission in my Integra has gone south. I expect it's some sort of horrid clutch problem, but I'm no mechanic, so I can't be sure. Basically, the problem is going into gear. For example it will only go into 1st from a dead stop about 75% of the time. Then the shift into second is often impossible, or at least difficult. I have to match revs perfectly with the gear to shift into the first 3 gears, almost as if the clutch weren't disengaging, and I was shifting without it (which is almost as easy now...).
In those intances where is won't go into 1st from stop, it often help to rev up just little, then it often fall into gear. I have to really shove the clutch pedal to the floor to get it to disengage, and sometime that doesn't even work.
If I try to coast to a stop with my foot on the clutch, but the car still in gear, the gear a little will still grip and push me forward, eventually stalling if I don't pull it out of gear.
I checked the transmission fluid, it's fine.
Please, could someone help me, it's obviously a big problem has manifested itself VERY quickly.

 

Definately sounds like it's not disengaging, but that could be several things.

How's your clutch fluid look?

 

Like I said, fluid's fine, it's the first thing I checked. It was on the lower end of the safe zone, but i topped it off and there was no improvement.

 

This happened in my friend's old BMW. It sounds like either your slave or master cylinder is dying, which doesn't let your clutch disengage fully, or at all.

I would try bleeding your clutch line thoroughly first, and if that doesn't do it, get new cylinders for it and install them before you toast your synchros.

Edit: My friend just replaced both cylinders in his clutch hydraulics and it has worked perfectly since then.
