getting into 1st...very hard sometimes
hi guys and gals,
just like the title says. sometimes when trying to get into 1st gear from a stop, it's very difficult. what does this indicate? or is this normal on my 02 z06. doesn't feel right.

Not sure if it applies to your situation or not, but I've noticed in EVERY car I've owned at some point or another that if the tranny isn't turning a little when you try to engage an gear it will not always go in. What I mean is that say you stop at a light, and hold the clutch in long enough for the input shaft to stop spinning, then shift from neutral into first and it doesn't want to go easily. If you keep it in neutral and let the clutch out partially (enough to get the input shaft turning again) and then engage first it's easy. It's bad to try and force a transmission into gear when it's not turning. I cringe anytime someone gets into a car with the engine off and just goes running through the gears. It'll tear up your synchros!!! Synchros are designed to match gear speeds on turning gears, not ones that aren't in motion. My $.02 worth.

If the velocity of both gears is zero, then by definition both gear speeds are already perfectly matched... how can the synchros wear out?

Is the shifter stock? You posted recently seeking an aftermarket shifter.
Even on the stock shifter, some owners have had the shifter cradle get loose and move too far to one side (left or right). The effect can be difficulty entering first gear or reverse. If that is your cause, the fix is re-centering the shifter cradle.

this was when the shifter was stock and still the same now that i put the b&m in. however- i didn't center the b&m correctly using that pin that i noted in the other thread. i will fix that tonight hopefully.

You can also release and engage the clutch again, this will usually get things aligned so you can get into first.

I have the same problem on my 02 Z06. From the searches I have done they say to let the clutch out and then back in and this will fix it. I have also noticed from personal experience if you rev the engine a little "something" (sorry I am not a mechanic) hapens to allow it to go into 1st with no problem.
