Can't downshift to second Gear until car is warmed up

Are you rev-matching when you down shift? Or are you just puttin the clutch in and then slipping it into a lower gear? You shouldn't have that problem if you are rev-matching.

might be a syncro

Is it just when it is cold, or does it happen everytime you start it up during the day?

I know that Honda 5-spd transmissions are notchy when they are cold. But if you can't downshift specifically down into 2nd gear, then I would think you might have syncro problems with 2nd gear.
What kind of tranny fluid are you currently using? If you're using synthetic transmission fluid, change it to Honda.

It really only happens when it is cold..I am using regular honda fluids. When I revmatch and downshift it will engage ..after a little effort..

Your tranny is going to wear over time. With it being a '94 - nearly 6 years old, this is definately going to happen.

Have the fluid changed if you haven't recently. Rev-matching certainly helps too.

Correct me if I'm wrong, but doesn't double-clutching do the same thing as rev-matching in this case? Just gets the synchros spinning at the same speed, right?
