Abstract
A vent for a motor vehicle transmission includes a housing attached to a bell housing of the transmission. A plate is mounted in the housing, and the plate has an open position to enable heat to dissipate from the interior of the bell housing through an 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. The vent is a passive vent with a biasing mechanism that moves the plate to the open position when an interior temperature of the bell housing reaches a predetermined temperature threshold and moves the plate to the closed position when the interior temperature of the bell housing falls below the predetermined temperature threshold.
