This assembly is a collection of electromechanical components crucial to the function of a specific automatic transmission model. These components control the flow of transmission fluid, thereby governing gear selection and overall transmission performance. The individual parts within the collection regulate hydraulic pressure based on signals from the vehicle’s computer, allowing for smooth and efficient shifting.
The appropriate functioning of this assembly is vital for maintaining optimal fuel economy, reducing wear on transmission components, and ensuring a comfortable driving experience. Historically, issues with these assemblies have been a common cause of transmission-related problems, leading to the development of improved designs and diagnostic procedures. Replacing a malfunctioning collection of solenoids often represents a cost-effective alternative to a complete transmission overhaul.
