The transmission fluid should be replaced on a regular basis. Regardless of having a manual or automatic transmission fluid, regularly changing it will avoid costly transmission repairs.Know More
Transmission fluid is a greasy lubricant for all moving parts inside a vehicle's transmission. In an automatic transmission, the fluid acts as a coolant, transmitting power from the engine to the transmission. Manual transmissions use different fluids, such as oils, motor oils and hypoid gear oils.
Most car manufacturers recommend a change in manual transmission fluid every 30,000-60,000 miles. For automatic transmission fluid, some car makers suggest a change every 40,000 miles. For practical purposes and to avoid expensive repair costs, the transmission fluid should be replaced regularly.Learn more about Transmission

More frequent changes do not harm the components.Full Answer >
Dexron is the brand name of transmission fluid manufactured for General Motors vehicles; Dexron-II was released in the 1970s, and Dexron-III was released in the 1990s. Dexron-III is considered to be backward compatible with other versions of Dexron, meaning it can be substituted for Dexron-II and other older versions of the fluid. However, as of 2014, neither version of the transmission fluid is currently manufactured or marketed, and the most current version, Dexron-VI, is used in a backward-compatible fashion with GM cars that require either Dexron-II or Dexron-III.Full Answer >
