Various systems and method are provided for heating transmission fluid by directing the transmission fluid through a cylinder block of an engine. In one example, the transmission fluid is directed to flow through the cylinder block of the engine while engine coolant is directed to flow through the cylinder head of the engine. Further, the transmission fluid may be directed through one or more heat exchangers to cool the transmission fluid.

1. A method for lubricating a transmission with transmission fluid, the transmission coupled to a vehicle engine, comprising: directing the transmission fluid through a cylinder block adjacent to a cylinder wall while flowing engine coolant through a cylinder head, without fluid flowing through a head gasket interposed between the cylinder head and the cylinder block;under a first condition, directing the transmission fluid to a heat exchanger; andunder a second condition, bypassing the heat exchanger. 2. The method of claim 1, wherein the first condition includes transmission fluid temperature above a threshold temperature. 3. The method of claim 1, wherein the second condition includes transmission fluid temperature below a threshold temperature. 4. The method of claim 1, wherein the heat exchanger exchanges heat between the transmission fluid and ambient air. 5. The method of claim 1, wherein the heat exchanger exchanges heat between the transmission fluid and the engine coolant. 6. The method of claim 1, further comprising adjusting an engine operating parameter based on transmission fluid temperature and engine coolant temperature. 7. The method of claim 6, wherein the engine operating parameter includes at least one of injection timing, spark timing, and valve timing. 8. A method for lubricating a transmission with transmission fluid, the transmission coupled to a vehicle engine, comprising: directing a flow of transmission fluid through a cylinder block adjacent a cylinder wall and maintained separate from a flow of engine coolant directed only through a cylinder head of the engine; andadjusting a first valve to direct the transmission fluid to flow through a heat exchanger before flowing through the transmission based on an operating condition. 9. The method of claim 8, wherein the first valve is a thermostat and the transmission fluid flows through the heat exchanger when a temperature of the transmission fluid is greater than a threshold temperature. 10. The method of claim 8, wherein heat exchange within the heat exchanger occurs between the transmission fluid and ambient air. 11. The method of claim 8, further comprising adjusting a second valve to direct the transmission fluid to a heater core based on temperature in a cabin of a vehicle. 12. The method of claim 11, wherein the second valve is opened when the temperature of the cabin is less than desired. 13. The method of claim 8, further comprising adjusting an engine operating parameter based on a temperature of the transmission fluid and a temperature of the engine coolant. 14. The method of claim 13, wherein the engine operating parameter includes at least one of spark timing, injection timing, and valve timing. 15. The method of claim 8, wherein there is no fluid flow through a head gasket interposed between the cylinder block and cylinder head. 16. A system for an engine in a vehicle, comprising: a cylinder block and a cylinder head with a head gasket interposed therebetween;a transmission lubricated by transmission fluid;a thermostat;a heat exchanger;a control system comprising a computer readable storage medium, the medium comprising instructions for: directing the transmission fluid through the cylinder block and adjacent a cylinder wall, and directing a flow of engine coolant through the cylinder head, with no fluid flow through the head gasket interposed between the cylinder block and cylinder head; andunder a first condition, directing the transmission fluid via the thermostat to the heat exchanger; andunder a second condition, bypassing the heat exchanger via the thermostat. 17. The system of claim 16, wherein the first condition includes a temperature of the transmission fluid above a threshold temperature, and the second condition includes the temperature of the transmission fluid below the threshold temperature. 18. The system of claim 16, further comprising instructions for adjusting a valve to direct the transmission fluid from the cylinder block to a heater core before directing the transmission fluid to the transmission, and wherein a transmission fluid pump is an auxiliary electric pump that continues to direct transmission fluid to the heater core when passenger cabin heating is desired and the engine is off while the vehicle is on in a hybrid vehicle. 19. The system of claim 16, further comprising adjusting at least one of spark timing, ignition timing, and valve timing based on a temperature of the transmission fluid and a temperature of the engine coolant.
