What is the throttle valve cable all about?
The throttle valve cable is a key component of a transmission system. The throttle valve cable is responsible for maintaining proper shift feel, controlling line pressure, and both partial and full throttle downshifts. The throttle valve cable is connected to the throttle lever, and is responsible for controlling it. Regardless of how much torque your engine is generating, the throttle valve cable will be able to keep the shift feel and transmission line pressure in balance.
Keep in mind:
- When the throttle valve cable is adjusted, the entire transmission system should be inspected.
- Replacing the carburetor can sometimes make it impossible for the throttle valve cable to be properly adjusted.
Your transmission is one of the most important parts of your vehicle to service. During maintenance and tuneups every part of the suspension should be checked, including the throttle valve cable. Always follow your car’s suggested maintenance schedule for the transmission.
What are the common symptoms indicating you need to adjust the throttle valve cable?
- Transmission (gear) does not shift properly
How important is this service?
The transmission is what is used to switch gears so that your vehicle runs smoothly and optimally. A key part of this system is the throttle lever, which keeps the shift feel and transmission line pressure in balance at all times. The throttle lever is controlled by the throttle valve cable. One of the key roles that the throttle lever and throttle valve cable play is that they’re responsible for downshifting your vehicle when it is going uphill. The throttle valve cable helps the engine find the right gear to maximize torque. When the throttle valve cable is not properly adjusted, a key component of the transmission is lost. Since the transmission is such a finely tuned machine, an unadjusted throttle valve cable can result in severe damage to the transmission.
