Hyundai Creta: Valve Body System / Valve Body

Description and operation

Description
The valve body is essential to automatic transaxle control and consists of various valves used to control the oil feed from the oil pump. Specifically, these valves consist of pressure regulator valves, oil redirection valves, shift valves, and manual valves.
The body also features electronic solenoid valves that ensure smooth gear changes.
