I need help diagnosing my **** transmission

I have attached two videos of the issue. This is the SECOND time this has happened to me!
I replaced the clutch release bearing and pretty much every other bearing in my trans after the first time.
that fixed the problem for about 1000 miles but its back. I'm tired of dropping it NGL..

What exactly is this WHINING NOISE? and what can cause it to come back within 1000 miles?

I really appreciate any advice on this issue.

( Cant attach videos but here they are )

 

In put shaft bearing ? From what I know the gear set has to be removed to replace it and I can see how to some that's a P.I.T.A. My 02 civic has made a hell of a noise for the 3-4 years I've had it but it's gone 100's of highway miles . The guy I bought it from said it had the problem but for $500** it was a cheap ride .

 

Wouldn't be throwout bearing? That's what I started thinking it was. It only makes the sound under load. Or with the clutch pressed in. It will still make the sound in neutral if rev'ed. Letting off the gas or going down a hill stops the sound.

 

I don't know but you should buy honda parts or OEM , Do the job correctly , pay attention to details and there shouldn't be any problems . I've bought a wheel bearing and it lasted about 20 miles , had to do it all over again . There's a lot of junk out there.
