New powerglide no low gear out of the blue (grinds)

So I just had a 1000hp rated glide installed in my measly 2800lb race car making right at 500hp.

Figure I'll never break this thing. Had the car out to the track once, ran great. Maybe driven 75 street miles on it. Today at a stop light I go to put the trans in low and it immediately makes a horrible grinding noise. Pop it back into 2nd and noise is gone. Drove home in second. Once I got it home I noticed it also grinds in reverse and neutral.

Anyone have an issue like this before?

Letting it cool off a bit before crawling under it to check things out.

Thanks all!

Well we tore it down today. Planetary lost 2 teeth stinking teeth. They were still crammed in the gear housings. Installed new 1.76 match planetary set and got her all back together. No good carnage pics. Just two little broken teeth. Dropping by the trans shop monday to flush the converter and I'll drop her back in.

thanks all.
