How do you unstick a 700R4 throttle valve?
the only possible quick fix for that is to “snap” the TV cable. with the engine not running, open the hood and find the TV cable on the driver side of the throttle body. push down on the bare cable until it bottoms out and let go quickly. repeat this 3 or 4 times and try to drive the truck.
What does the governor do on a 700R4?
The transmission governor on a 700R4 is used to regulate the speed at which the transmission shifts into the next higher or lower gear. It accomplishes this through the use of two sets of centrifugal weights, each a different weight.
How do you fix a sticky transmission valve?
Replace filter or clean screen (most have filters made out of fiber) Clean magnets stuck to bottom of pan. Reinstall pan with a new gasket (some use a molded rubber reusable gasket) Refill transmission with correct type of fluid to recommended level.
How does a 700R4 work?
The 700R4 uses a cable that connects the throttle linkage to the transmission’s throttle valve (TV) in the valvebody. This is the governor that commands WOT up-shift speeds. The cable moves the throttle valve in the valvebody and increases transmission line pressure as the throttle opens.
How do I know if my transmission governor is bad?
Some of the most common signs of a bad transmission control module include:
- You have difficulty downshifting when you’re slowing down, coming to a stop, or manually trying to downshift.
- You have difficulty upshifting when you’re trying to accelerate or manually trying to upshift, which can cause a delay in acceleration.
What causes a stuck transmission?
You Have a Stuck Solenoid Your car’s computer sends electrical signals to the solenoids, opening them up allowing transmission fluid to flow through them and allowing the gears to shift. The most common cause of a stuck solenoid is the failure to replace your transmission fluid when you should.
How do I know if my transmission valve is bad?
Symptoms of a Failing Valve Body
- Delayed Garage Shifts. One of the most common symptoms of a failing transmission valve body is a delay in shifting or harsh shifting.
- Incorrect Shifting. When driving, you could notice the transmission shifting into higher or lower gears at the wrong time.
- Shift Flares.
- Gear Slippage.
What does AOD governor do?
AOD GOVERNOR VALVE CLEAN/REPLACE: The governor valve senses the output shaft speed via centrifugal force of this valve against line pressure. The effect of the governor valve has an effect on shift points for all gears through the entire RPM range.
