Vehicle transmission fluid cooler

A transmission fluid cooler for cooling transmission fluid of a transmission having a housing with a power take off access opening and having a thermal sensor for sensing a temperature of the transmission fluid, the transmission fluid cooler comprising:

• a perimeter mounting flange for mounting to the housing of the transmission, said perimeter mounting flange defining a hole for fluidly communicating with the access opening when said perimeter mounting flange is mounted to the transmission housing, said hole of said perimeter mounting flange having a rectangular configuration;
• said perimeter housing flange having a substantially rectangular configuration, said flange having a pair of end portions and a pair of side portions, said perimeter housing flange having a plurality of apertures, each of said end portions having one of said apertures, each of said side portions having a pair of said apertures, said apertures of said flange adapted for receiving fasteners adapted for securing a power take off plate to the power take off access opening of the transmission;
• a body portion having a bottom wall and a peripheral wall, said peripheral wall extending upward from a periphery of said bottom wall such that an interior surface of said peripheral wall defines an interior of said body portion, said perimeter wall having a terminal end opposite said bottom wall, said terminal end of said peripheral wall being united to said perimeter mounting flange about said hole such that the interior of said peripheral wall is aligned with said hole for permitting transmission fluid of a transmission on which said perimeter mounting flange is mounted to flow through the access hole and said mounting flange into the interior of said body portion;
• a plurality of substantially rectangular fins being equidistantly spaced around an exterior surface of said peripheral wall of said body portion, said fins extending outwardly from said exterior surface of said peripheral wall such that said fins orthogonally extend from the exterior surface of said perimeter wall and from said perimeter mounting flange to an outer surface of said bottom wall, said fins being in thermal communication with said interior and exterior surfaces of said peripheral wall for transferring thermal energy from the transmission fluid to air surrounding said fins;
• and
• wherein said interior surface of said peripheral wall of said body portion and an interior surface of said bottom wall of said body portion are each substantially flat for facilitating movement of the transmission fluid between the transmission and said body portion.

A transmission fluid cooler system comprising, in combination:

• a transmission having a housing with an access opening;
• a perimeter mounting flange for mounting to said housing of said transmission, said perimeter mounting flange defining a hole for fluidly communicating with the access opening when said perimeter mounting flange is mounted to said housing of said transmission;
• a body portion having a bottom wall and a peripheral wall, said peripheral wall extending upward from a periphery of said bottom wall such that an interior surface of said peripheral wall defines an interior of said body portion, said perimeter wall having a terminal end opposite said bottom wall, said terminal end of said peripheral wall being united to said perimeter mounting flange about said hole such that the interior of said peripheral wall is aligned with said hole for permitting transmission fluid of said transmission on which said perimeter mounting flange is mounted to flow through said access hole and said mounting flange into the interior of said body portion;
• a plurality of fins extending outwardly from an exterior surface of said peripheral wall of said body portion such that said fins are in thermal communication with said exterior and interior surfaces of said peripheral wall for transferring thermal energy from the transmission fluid to air surrounding said fins;
• and
• wherein said interior surface of said peripheral wall of said body portion and an interior surface of said bottom wall of said body portion are each substantially flat for facilitating movement of the transmission fluid between said transmission and said body portion.
