Press F everyone.
As of now, here's what happened:
(Vids:

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.
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.
Vehicle repeats what I described earlier (struggling to move, etc) after a few minutes driving.
Called Tripple A, had to get it towed to a shop
