Hi All. When I shift from 2nd to 3rd the car almost stops. Don't notice it at speed but when cruising at light throttle, back to the pit it almost throws me into the dash pad  I rebuilt the trans at the begining of the season, been doing it all the time but i had other stuff to sort out. What have I done wrong? TIA
