Understanding your vehicle's Automatic transmission fluid and the importance of its maintenance

Automatic transmission fluid helps transmit engine power, enables gear changes through hydraulic pressure, lubricates internal components and dissipates heat. Over time, heat and contaminants can affect the transmission fluid's ability to perform its functions properly. It is recommended to inspect the transmission for any leaks, check the fluid level regularly and change the fluid at the specified intervals.
