Manual "jingle" when clutch out and in neutral

[Long Island RT]

I have a Tremec 5 speed and notice a slight jingle coming from the trans when it's running in neutral with the clutch out.
I was very careful when following the directions for shimming the hydraulic clutch upon installation and it works flawlessly.

It may be normal, but IDK.

Any thoughts?

Maybe the oil level is low? Is this happenning only when warm or at any time? If when warm, maybe the trans needs the cushioning of a thicker lubricant?

Throw out bearing.  Apply pressure lightly and see if it goes away?

[Long Island RT]

Yes - any pressure and it goes away.  The throw out bearing is the hydraulic unit that came with my kit.  It's all brand new - only 600 miles.
I'll see if I can peak in there and see if something looks off.

I used Royal Purple Synchromax Manual Transmission Fluid - as directed in the assembly instructions.

"Neutral Gear Rattle". A piston engine's power delivery is not seamless like an electric motor; a piston engine makes pulses of power very rapidly and the pulses can make the clearance between the gears in the trans cause a "rattle" with each pulse.

Some transmissions are more susceptible to it than others and the chassis can amplify the sound.
