my car has been juckin to second for the last year it a automatic i was wondering is cause of my underdrive pulley

 

juckin = english ?

 

meaning it feels like someone is doing a quick tug on the car when it shifts to second

 

year? usually the accord automatics have a rough shifts...but that may just be for the cd5's which is what i have

 

Jerks?

There can be a rough transition between gears in some year accords, I've experienced it on my 97.

 

should i remove my crank pulley an put back the alt pulley

 

the pulleys have nothing to do with shifting... check your trans fluid or have it replaced/serviced. Maybe its gunking up inside and causing the harsh shifts.

for what its worth, nearly all hondas I've driven have a momentary jerk between the 1-2 shift. Its normal.
