T56, LT1, Hard to get in gear/pop out.
1995 z28 T56, 120,XXX miles.
1st gear is hard to get into when I'm stopped. Not too sure how much it happens, but it doesn't happen every time. I can usually get it in by shifting into second, then pushing forward pretty hard. It feels like it is hitting something.
My second gear pops out occasionally. It happens when I shift into 2nd and not give it any throttle for a few seconds, then when I give it gas it will pop out. When it pops out, it feels like it doesn't go all the way back to neutral. If I try to push it back into gear, it will grind. I have to shift into neutral, and put it back. After the gear has been in for a little bit under power, it won't pop out. I recently installed the stock Hurst shifter that came with some LS1s, and I still had the same problem, albeit less often.
I'm wondering what could be wrong, and how I can diagnose it. Also, should I fix soon before it breaks completely, to avoid damaging other parts? Sorry if I missed any threads with this, I tried to search.
Thanks in advance!

Your 1-2 synchro assembly needs to be replaced. You might even need a new 2nd gear. There has been a re-design of that gear, with longer engagement teeth. Since yours is an LT1, it has the old style for sure. At any rate, its time for a rebuild.

Thanks for the quick replies. Can I drive it until it gets hard to stay/get in gear, then rebuild, or should I do it asap to prevent damage to other parts?
