nv3500 problems

[Devrin]

Transmission is in a 94 k1500 and was rebuilt less than 3,000 miles ago and has gm synchromesh in it. It developed a high pitch squeak/chirp in ONLY 3rd and 4th when fluid is warm. The new clutch that was installed makes a growling noise when disengaged. Just looking for advice of something it could be before just changing the clutch and have that not be the problem

maybe a loose or bad pilot bearing?

That isn't the clutch. The clutch would be growling in and chirping in all gears. Growling and chirping makes me think of a bad bearing trying to spin on a shaft as it warms up. Whoever rebuilt it better check it out and warranty it.
