I went away for spring break, and when I got back, my car was giving me a bunch of trouble with shifting. Its a 1994 del Sol VTEC (B16A3), manual. The symptoms I've noticed:

* It's very hard shifting, almost like the synchros are gone. I can shift mostly okay as long as I'm going slower than ~30 MPH, but any faster and I have to rev-match pretty perfectly to avoid grinds. This holds for any gear I try to shift into at that speed.

* The clutch seems to chatter when I start moving, both in reverse and first gears.

* Occasionally, when I'm stopped in gear with the clutch out, the car will jerk, like I let the clutch in and then back out really quickly.

None of these happened before break. I thought that the hard shifting might be caused by bad tranny fluid. It's got "El Cheapo" 10w-30 in there right now, I have Honda MTF for it but I've been waiting until I can find an LS 5th to swap in to change the fluid. And the other symptoms wouldn't have anything to do with the fluid as far as I can tell.

Anyone have similar problems before?
