Where is the Governor located in a transmission?
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). 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.
What is the transmission governor on a 700R4 used for?
The transmission governor on a 700R4 is used to regulate the speed at which the transmission shifts into the next higher or lower gear.
How do you remove the governor from a car?
Remove the governor by pulling it out with a slight clockwise twist. Different weights can be obtained to change the shift points on the transmission. This is very useful for towing or in the event of a gear change in the differential.
What happens when the governor pressure goes up?
Now you take your foot off the break but don’t hit the gas. The car will slowly speed up and the governor pressure will go up. When the governor pressure is high enough it will overcome the spring and slide the spool valve over turning off first gear and turning on second gear.
How does the Governor of a transmission work?
Governor pressure increases with vehicle speed. Older transmissions had mechanical governors that consisted of springs, centrifugal weights, and a spool valve to control this pressure. Electronic transmissions use the vehicle speed sensor signal for vehicle speed.

How does the Governor affect the shift timing?
Governor pressure increases with vehicle speed. Older transmissions had mechanical governors that consisted of springs, centrifugal weights, and a spool valve to control this pressure. Governor pressure causes a transmission to upshift, and throttle pressure causes it to downshift. Today’s transmissions use solenoids for the shift timing.
