Engine rumble
 

Engine begins to rumble when I begin to accelerate happens when its warming up as I take it for a spin, then it feels like it hesitates to change gears then I get a funky burning smell coming from the car....I changed the oil and filter, I added 1qrt of trans fluid as well.

Also forgot my car turned off on the freeway I tryed turning it back on minutes after and it hesitated to start and I heard like a screeching noise.
