A device designed for servicing automatic transmissions, this equipment replaces old fluid with new, often incorporating a cleaning process to remove debris and contaminants. This process typically involves connecting the device to the transmission lines, allowing it to pump out used fluid and simultaneously introduce fresh fluid. Some advanced models offer features such as integrated heating systems for optimal fluid viscosity during the exchange.
Maintaining clean, high-quality fluid is vital for optimal transmission performance and longevity. Contaminated fluid can lead to decreased efficiency, rough shifting, and eventual component failure. This service, once considered supplemental, has become increasingly important with the complexity of modern automatic transmissions. Regular maintenance using such equipment can prevent costly repairs and extend the operational lifespan of the transmission.
