As of now, here's what happened: ​(Vids + photos: https://photos.app.goo.gl/rX6HXe9PyKZMptex6 )

Driving normally down a residential street, doing 25MPH at most. RPMs are steadily going higher, up to the point where it sounds as if im reving it (even though im not)

I checked the dipstick, no signs of metalic substances or discoloration, fluid is at appropriate level.

When accelerating, the vehicle feels as if its struggling/unable to move, and it even vibrates alot. I compare this to wheels seizing up and being dragged on pavement. When in reverse, nothing happens.

I put it in neutral, moves foward and back as it should.

Had to go somewhere so I park and return an hour later, the vehicle actually moves as if nothing happens (foward and back in gear)

Vehicle repeats what I described earlier (struggling to move, etc) after a few minutes driving. When put in reverse, nothing happens.

Called Tripple A, had to get it towed to a shop

Transmission: 4L60E, US Shift Quick 4, External Hayden Transmission Cooler, 20k miles on it Vehicle: 1990 Chevy K5 Blazer, 85' 6.2 Detroit Diesel w/h ATS Turbo Kit..

I replaced the bulbs a few months ago on the instrumental cluster and headlights aswell (194 incandescent). The guages always seems dim no matter what, and the headlights themselves never seem to illuminate as bright as they should.

Is there a wire(s) that power on the interior that I should look at? Maybe a headlight wire isnt that good too? Perhaps a ground?

Id just like my dash to be as bright as it once was

Trying to figure out a decent PSI, my application is strictly highway driving (nyc).

I currently have the factory AC Condenser, AC Compressor (no belt on it currently) ,Suction Accumulator/Drier, and AC Evaporator Core on the vehicle as of now.

The North East summer is getting to me and I am heavily considering putting AC (back) on it, now the question is, what is the best route can I take to achieve this, given that I have much of rhe factory components on it (I am aware of vintage air, but if i can get the OEM system running thatd be great, yes im aware of the R-12 question).

Any advice/guidance would be highly appreciated, thank you.

I know im not going crazy when I say that chirping noises can be heard in the video.

No there isnt any vibrations or shaking, nor any "howling" noise, all i hear is what sounds like chirping when in drive. again it drives and shifts smoothly

What is the consensus here? Im tired of loosing my mind over a damn squeak/chirp, dont necessarily want to blow something down the LIE either.

Ive been hearing a squeaking noise come from underneath the body, the noise has disappeared three or so days ago, but I cant let go of the feeling im perhaps missing something. (It only squeaked when in reverse)

Does it seem to shift well? (Especially from P to D/R) K5 itself is at 300K miles)

Linked below will be all photos/videos regarding the Driveshaft, along with how the front and rear differential looked like when I changed the fluid 7 months ago (prior to a 700 mile trip from SD to NYC)
