Transmission fluid is a slippery substance that lubricates all of the moving parts inside your transmission. In an automatic transmission, this fluid is a coolant and viscous agent that transmits power from the engine to the transmission. While automatic transmission vehicles use transmission fluid, manual transmissions use a variety of oils including regular motor oil, heavy duty gear oil or sometimes automatic transmission. Routine maintenance is the best way to prevent costly transmission failure. S&S Tire recommends transmission service every 30,000 miles.
Symptoms your transmission may need service:
Transmission slipping between gears (rough shifting)
Loss of power
Unusual noises when accelerating
S&S Tire will:
Inspect transmission for wear
Check transmission fluid level
Replace transmission fluid
Why is transmission maintenance important?
Both manual and automatic transmission cars will experience transmission fluid contamination over time. As the synchronizers, bearings and gears in the transmission wear out, metal particles float around in the lubricant. Since dirty oil does not perform as well as clean oil, the contaminated oil must be drained out, or it will adversely affect the life of the transmission. In automatic transmission cars, the fluid actually degrades with use, due to the heat generated in an automatic transmission.
