Is a kickdown cable necessary?
In fact, if you don't mind downshifting manually with the shift lever when passing, there's really no need for a functional kickdown cable or switch at all. Even manual downshifting to obtain passing gear may not be needed in the ultralightweight T-bucket's case because it has so little inertia.
Where is the kick-down cable?
On the side of the carburetor or throttle body will be a set of wire cables. Typically there are two or three of these cables. One is for the throttle and the other is the kickdown cable.
What happens when a kickdown cable goes bad?
The transmission shifts slow and late In this scenario, the kickdown cable is typically stretched and will cause a delay in the shifting process. Like the above warning sign, this problem may impact the performance of other, expensive to replace components like the driveshaft and flywheel of the engine.
How does a throttle kickdown cable work?
These springs serve to pull the throttle butterfly back into the lower position when the driver takes his or her foot off of the gas pedal. This also serves to pull the kick down cable automatically back down into the lower gear as the need for higher gear due to increased engine revolutions per minute is decreased.
How does a kick down solenoid work?
Then the kick-down valve opens and pressure applies to 1-2 and 3-4 gears. When the gas pedal is depressed, the solenoid gets cut from current, but the valve stays open. When the RPM value grows, the valve closes under the pressure.
Where is the kick down button on a transmission?
The kick-down button is located under the gas pedal. It is necessary to press the gas pedal to the floor to activate the kick-down mode. The transmission will switch to the normal mode of operation as soon as the driver takes his foot off the gas pedal.
Is it safe to use kick down mode on a car?
It is also not recommended to use the kick-down mode when there are some other issues with the car or its transmission. It is very risky to use the kick-down in the car with technical malfunctions. In this case, it is better to avoid sharp accelerations and to consult repair specialists.
Is it better to drive in kick down mode or not?
Finally, driver should not go too far with the kick-down mode and use it too often. It should be understood that even if the kick-down is provided and approved by the car manufacturer, sharp accelerations give increased loads on all mechanisms of the automatic transmission and sooner or later it may lead to the transmission failure. Moreover, each case of sharp acceleration causes increased fuel consumption. Therefore, it is better to drive safely and to use the kick-down mode reasonably.
What is the kickdown cable?
One component that helps both drive systems communicate is the kickdown cable. This device helps the engine relay information on revolutions per minute (RPM) to the automatic transmission and essentially tells it that it's time to shift gears. Like any other component under the hood of your vehicle, it is subject to wear and tear ...
What happens if a kickdown cable is stretched?
In this scenario, the kickdown cable is typically stretched and will cause a delay in the shifting process. Like the above warning sign, this problem may impact the performance of other, expensive to replace components like the driveshaft and flywheel of the engine.
Why is my transmission cable damaged?
The cable can be damaged due to aggressive driving where the automatic transmission makes multiple up and down shifts. The more jerking and shaking the transmission does on the road, the more damage is possible to the kickdown cable and other transmission components. 2. The car shifts early and fast. A shift to a higher gear is supposed ...
Can you replace a kickdown cable?
But, if the cable has broken, it may result in a complete transmission rebuild. Be proactive, and contact a mechanic from YourMechanic.com if you notice any of the above symptoms so they can replace the kickdown cable for you.
Why do automatic transmissions kick down?
Automatic transmissions kick down to a lower gear to make use of the greater power delivered at the engine’s higher rpm; this typically occurs when the driver attempts to accelerate from a constant speed, as if to pass.
Does a transmission kick down?
In the best applications, the driver never thinks twice about it. In less ideal circumstances, the transmission doesn’t kick down readily enough, resulting in a lack of needed power — or perhaps the opposite, it kicks down more frequently than the driver would like, which is especially a problem if the kickdown comes with a delay in the downshift.
What Is A Kick-Down?
- Kick-down is the mode of operation whichprovides the maximum possible acceleration in the car equipped with theautomatic transmission. It is important to point out that the kick-down mode isavailable only in automatic transmissions when the driver pushes the car'saccelerator (gas pedal) to the floor. This action forces the automatic transmissionto ...
Usage of Kick-Downmode
- The kick-down mode can be engaged only atreduced engine RPM. Commonly, the kick-down mode should be activated when the topgear is engaged; otherwise the process of acceleration won’t be intensiveenough. The kick-down button is located under the gas pedal. It is necessary topress the gas pedal to the floor to activate the kick-down mode. The transmissionwill switch t…
Principle of Operation
- As it has been mentioned above, the kick-downshift knob is located under the gas pedal in cars equipped with automatictransmissions. When the knob is pressed, it transmits a signal to the ECU thatthe car requires an urgent acceleration. The ECU, in turn, is responsible fordownshifting and helping the engine to achieve optimal RPM for the maximum acceleration. A current is applied t…
Can Kick-Down Be Harmfulfor Your Car?
- Manufacturers of automatic transmissions claimthat the kick-down mode should be used at least once a day to prevent stickingof the kick-down valve. But according to many auto mechanics, frequent usage ofthis mode may lead to wear of engine and transmission components because ofoverloads. Therefore, many owners of cars equipped with automatic transmissionswith the ki…
