The symptom you've described, hard shifting into gear, can be caused by a
worn clutch and does not necessarily indicate a problem with the
transmission.

One way to evaluate the transmission is to depress and release the clutch
pedal with the engine running and the transmission in neutral. If you hear
any change in the sound coming from the engine compartment, then it could be
associated with the transmission. For example, if a noise goes away when
you depress the clutch pedal, then the transmission might have noisy
bearings. Or if a noise becomes audible when the clutch pedal is depressed,
then it might be the clutch release bearing (something which is replaced
with the clutch so it's not a big deal).

Other problems that can occur are with the clutch release cable. Sometimes
the wire cable saws through the metal housing at the transmission end. This
can cause the cable to hang up and might prevent the clutch from fully
engaging thereby accelerating wear on the clutch. Another problem, which is
more common on Civics, is that sometimes the spot welds in the pedal cluster
come apart. This allows the pedal cluster to flex which then doesn't allow
the clutch to be fully disengaged while shifting.

Also make sure that the clutch is adjusted correctly. There should be about
3-5 mm of free play at the end of the clutch release arm. If there isn't,
then you'll need to back of the adjusting knob on the cable a little bit.
However, too much freeplay can cause the transmission to be hard to get into
gear especially with a worn clutch.

Lastly, manual transmission fluid should be replaced about every 30K mi. If
you change the oil, be sure to check it's condition. Make sure that you
don't see any sparkling metal flakes in it which would indicate failing
internal components.
