Ok, now that we've corrected that issue...
Does it ever have trouble shifting at any other time, under any other circumstances? I'm assuming you have the manual transmission, AX-5. Verify that. If so, I would drain and refill with some synthetic fluid immediately. First choice would be Red Line MT90. Second choice should be the Pennzoil Synchromesh. The PS is not synthetic, but it's smooth. If you go to a quick lube place to have it done, call to make sure they have one of these two fluids. If not, go find it at the auto parts store and take them 4 qts. You should have about 1/2 quart leftover.
Good luck.

ps. hope I didn't come off as pissy with the "car" thing. Just something between Jeepers... sometimes best learned the hard way.
