Manual transmission noise

I’m sure this has been discussed before but I can’t seem to find in search engine so here I go.
I recently purchased 2012 Rubicon with 280k original miles. Engine is from 2014 with currently pushing 26k. Transmission has been completely rebuilt and has new transfer case.
I seem to hear slight rattling noise at around 2-2.5k rpm in 2-3-4 gears every now & then. When I push the pedal hard it goes away. Some say it’s normal or “Jeep Thing” but I’m afraid it’ll lead to some technical failure in the future.
Also in higher gears 4-5-6 it has a slight whistling sound.
I’ve been driving manual cars since 90s & to me it doesn’t seem quite normal.
Maybe the guy who rebuilt did crappy job. Idk.
Does anyone have better idea? Help me out ppl.

You answered your own question, “ maybe the guy who rebuilt it did a crappy job”. That would be my guess.

After watching some YouTube videos it seems quite common and mine isn’t as bad. But it bugs me & I’d like to know what’s the cause & if there’s anyone here who’s had that issue either solved or had long term with or with no problem. Also is the clunking noise normal when letting go the clutch? I never drove another Wrangler with NSG370 so I can’t compare.
