Gasket with a baffle

1. A motor vehicle transmission comprising:

a transmission housing;

a shift tower housing configured for mounting to the transmission housing;

a gasket with an outer band that defines an inner open region, the outer band having an enlarged portion; and

a baffle located in the enlarged portion, the gasket being disposed between the transmission housing and the tower housing, the baffle including a flap portion connected to the enlarged portion along a segment, the flap portion being deflected into a minor chamber of the transmission housing by the positioning of a vent in an opening of the tower housing such that the flap portion is moved away from the opening, the vent communicating with the minor chamber,

wherein heated air and pressure buildup in the minor chamber is dissipated through exit openings of the vent, and

wherein the positioning of the flap in the minor chamber deflects hydraulic fluid into the minor chamber away from the vent such that the baffle prevents or minimizes the escape of hydraulic fluid from the transmission through the vent during the operation of the transmission.

2. The transmission of claim 1 wherein the baffle includes a gap that enables the release of heat from the transmission housing.

3. The transmission of claim 1 wherein the gasket forms a seal between the shift tower housing and the transmission housing.

4. The transmission of claim 1 wherein the flap portion and the enlarged portion define a gap that extends around the flap portion that is not connected to the enlarged portion along the segment.

5. The transmission of claim 4 wherein the gap is about 2 mm.

6. The transmission of claim 1 wherein the thickness of the gasket is between about 0.4 mm and about 0.8 mm.

7. The transmission of claim 1 wherein the baffle enables the release of pressure buildup within the transmission housing.

8. The transmission of claim 1 wherein the gasket is made of a fibrous material.

9. The transmission of claim 8 wherein the fibrous material is paper.
