Claim:
1. A vent for a motor vehicle transmission comprising: a housing attached to a bell housing of the transmission, the housing having an opening; and a plate mounted in the housing, the plate having an open position to enable heat to dissipate from the interior of the bell housing through the opening of the housing and a closed position to prevent debris or water from entering through the opening of the housing into the interior of the bell housing, wherein the vent is an active vent with an actuator that moves the plate to the open and closed positions, the actuator including a first projection that engages with a second projection attached to the plate, the actuator extending the first projection when an interior temperature of the bell housing reaches a predetermined temperature threshold so that the first projection pushes against the second projection which causes the plate to move to the open position.
