Default Grinding in 1st?

My car is a stock 2000 ss and when ever i try to downshift into first at any speed that isnt a slow crawl it grinds. Is this normal?

Blocker rings are probably toast. Same thing in my car, can't get it into 1st unless I'm at a dead stop and the trans has stopped spinning. I'm tearing into it as soon as the weather warms a little.

Every trans has a magic rpm that in theroy you do not need to use the clutch to shift. I've seen it work, thats prob what your exp. It should not be grinding.

Why are you downshifting into 1st at 20mph anyway.

it's called rev matching

You have to be dead on for it to go in else you put a LOT of strain on your syncros and additional wear.

To the op: Why are you downshifting at that speed? I only use 1st to launch, crawl in parking lots.
