The SAE has a separate viscosity rating system for gear, axle, and manual transmission oils, SAE J306, which should not be confused with engine oil viscosity. The higher numbers of a gear oil (e.g., 75W-140) does not mean that it has higher viscosity than an engine oil 20W-50.
The viscometrics for gear oils are standardized in SAE J306. Multigrade gear oils are becoming more common; while gear oil does not reach the temperatures of motor oil, it does warm up appreciably as the car is driven, due mostly to shear friction (with a small amount of heat conduction through the bellhousing from the engine block).
Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an automatic transmission. It is formulated to ensure smooth valve operation, minimize brake band friction, facilitate torque converter function, and provide effective gear lubrication.

SAE J306 is a standard that defines the viscometric properties of automotive gear oils.It is maintained by SAE International. [1] Key parameters for this standard are the kinematic viscosity of the gear oil, the maximum temperature at which the oil has a viscosity of 150,000 cP, and a measure of its shear stability through the KRL test.
The early California oil industry has served as a setting for several notable fictional novels and films: Oil! (1927), a novel of social criticism by Upton Sinclair is set against the background of the California oil industry and is loosely based on the career of Edward Doheny and events related to the Teapot Dome scandal.
