How does a governor work in a transmission?
How does a governor work in a transmission?
The governor has a set of fly weights (like centripetal advance in a distributor). As you drive faster the weights fly out more closing the valve and raising pressure. Finally everything comes together. The transmission uses spool valves to shift.
When do you need a new transmission valve body?
If one of these solenoids were to fail, you may find yourself locked out of certain gears, or you may be unable to shift at all. A qualified transmission shop may be able to replace a single component inside the valve body, or you may need a new valve body depending on what the root cause of the problem is.
What happens if your transmission valve is not working?
Your shifter should never slip out of gear if your transmission valve body is fully functional. If the transmission is not able to downshift, then hydraulic fluid may not be entering or navigating the transmission valve body properly. Once this happens, the gears cannot be pressurized properly which degrades the performance of the vehicle.
How is governor pressure similar to throttle pressure?
Governor pressure is similar to throttle pressure in that it is a derivative of line pressure but it is generated relative to the speed of the vehicle. Normally the governor is in or near the tail shaft of the transmission. The governor has a set of fly weights (like centripetal advance in a distributor).
Can a transmission valve be replaced at home?
There are many tiny components inside a transmission valve body that must function exactly as designed for proper transmission operation. If you take your vehicle to a qualified transmission repair shop, there is a chance that the shop may be able to replace an individual component instead of the entire valve body.

What is the body of a transmission valve?
Not to be confused with the intake and exhaust valves in your engine, the valve body is an assembly inside an automatic or CVT transmission that routes automatic transmission fluid (ATF) throughout the transmission.
