hey i have a 96 a4 2.8 auto

when i drive like 15-20, the second gear just jerks like at 2000 rpm and the rpm will go to like 2200 rpm when it shifts to second gear. anyone know what this can be.

i just had a thought; i just wanted to know if the little hoses next to the intake(its like small tubes/hoses that carry air) i think that they might have a hole in them because i was working in that are and i think i ripped it, not sure. what is the functions of those small tubes/hoses. and if anyone can tell me why i am getting the jerk on the second gear.
