  • The further the gas pedal is pressed, the more pressure is put on the throttle valve. Other cars use a vacuum modulator to apply pressure to the throttle valve.

    In your car's transmission, the transmission valve, or transmission modulator valve, is used to control the point at which gears are shifted.

    Vacuum Modulator is an engine load sensing device that converts engine vacuum into a transmission valve body input. Most vacuum modulators operate with.

    Vacuum modulators in some transmissions were essential in the proper operation of many automatic transmissions. The modulator valve works together with the governor or throttle of your engine to determine appropriate speeds for shifting gears. Different pressures are needed for the valve body to detect which gear you're shifting into. Saved Vehicles 0 Saved Searches 0. This page was last edited on 18 February , at

    The transmission valve body is the brain of the transmission. It controls the transmission shifts and directs the appropriate fluids into the appropriate passages to aid in the shifting. All of this enables your transmission to work properly and avoid damaging your entire transmission. Metal Debris Metal debris can cause scoring on the fluid passages, which can affect shifts, because proper pressure will not be maintained.

    Metal debris can also cause the O-rings to fail, causing a fluid leak in your transmission. If metal debris blocks fluid passages, the pressure needed to obtain proper shifts can't be maintained. Different pressures are needed for the valve body to detect which gear you're shifting into.

    Improper Lubrication A weak transmission pump can cause improper lubrication in a transmission valve body, which could cause metal to metal contact. This can cause unnecessary wear, causing the gears to stick or fail. Unnecessary wear can cause metal debris, which can lead to other problems.

    The lubrication also enables the transmission to cool itself, so improper lubrication can lead to overheating. Worn Fluid Worn fluid causes the lubrication to lose its viscosity, which decreases the level of protection the transmission fluid passes through. You can easily prevent this by checking and changing your transmission fluid on the appropriate schedule.

    This is generally every 15, to 30, miles, unless needed sooner based on the use of your vehicle. If you do a lot of heavy hauling, you work your standard or automatic transmission harder and will need to change the fluids more frequently.

    The transmission valve, or transmission modulator valve, controls the point at which gears are shifted. The modulator valve works together with the governor or throttle of your engine to determine appropriate speeds for shifting gears.

    If the transmission modulator valve is faulty, it will usually result in your automatic transmission not being able to shift gears and may also result in a lot of smoke from your transmission or manifold area.

    Tools and Materials New transmission modulator valve Hydraulic floor jack Jack stands Set of wrenches Purchase a Transmission Modulator Valve Visit your local auto parts store or car dealership that sells your make and model vehicle and purchase a transmission modulator valve that is compatible with your vehicle.

    Raise the Vehicle Using your hydraulic floor jack, raise the vehicle to a height slightly higher than the jack stands that you will use to support the vehicle. Place jack stands in appropriate support areas to help support the vehicle while you are repairing it.
