09 Taco 6sp tranny speak running/not running

So, I put a stage 2 clutch from clutch masters and 40lb flywheel 2 yrs ago. I also have the metal sleeve and bearing kit.
When I initially heard the squeal/squeak was in 2021 and I got the sleeve kit and had a shop put it on and the little cover between the block and tranny (it clips in) they forgot it and when i put my clutch on and all the upgrades I thought something was because there was a hole, a gap, making look like something was missing.

I did my investigating, and I bought one, but I lost it in a rush job of a move.

So, the problem:
When it's not started, I push in the pedal and it squeaks, when I drive it, it squeaks for a while, but after some time it goes away, or I can barely hear it if I'm stopped next to a car of building.

When it's first starting out in the morning, I hear the squeak on the release or sitting in neutral it's louder.

I friend said, 'sounds like something needs greased.'

If so, how can I grease it without tearing it apart as I live in a trail park with awful HOA nonsense? My driveway is not conducive for truck repairs.......the slop is dangerous either way you try.......slops to the left and then downhill.

So please help.
