Default transmission grinds from first to second

Sounds to me like your clutch is not engaging the whole way....might be time to upgrade your clutch.

Just another option: Because you notice this only when you push on it, it is important you make sure you are completing the throws.

I had this problem. My blocker rings were busted, and my syncros were on their way out. I waited to long and messed up the gear also. (I bought the car used, it was already doing it) Anyway, I had my tranny taken apart and that was the problem. The rest of the tranny was fine, but the 1-2 moving parts were all screwed up.

The gear was about $140, the blocker rings are more though. I just had a complete transmission overhaul done with upgraded parts, I am now warranteed up to 700 HP.
