how many gears does the left front window motor have on 2004 GMC Canyon

I am purchasing a power window motor for the front drivers door and having replaced by an independent shop. The parts store tells me there are 2 motors available. One with 8 gears and the other with 6 gears. Which do I need. If the window rolls down (very slowly) you have to beat on the lower part of the door and it will zip right up.
