How important is it to vent the ring and pinion area of the transmission> what does this accomplish. I have heard that this is important. mine is not vented and it is mounted in the car already. it works perfect, i have not had a problem withit however i only have about 10 hours on it. is it worth the time to remove my motor and transmission to drain it, take the bell housing off, drill and tap it, then vent it? what do you guys think.
