Do car transmissions have valves? The transmission valve body is a part of the transmission system of a car that controls the transmission fluid and directs it into valves to keep the gears functioning smoothly.
Are there valves in a transmission? All automatic transmissions have a valve body that acts as the brain of the transmission. Within, there are dozens of passages and channels that direct the flow of hydraulic fluid to different parts of the transmission. … Each valve has a different purpose and they are named to reflect that job.

If your transmission fluid is deep red or brown, your transmission fluid is old and most likely causing extra damage within your transmission. If it is dark brown, that is a sign you have burnt transmission fluid from overheating.
What speeds up the transmission of nerve impulses?

High voltages are used in transmission systems because a higher voltage implies a lower current for a given power of transmission. With a lower current, less heat is generated in the transmission lines and so less energy is wasted.
