What does the detent cable do?

The kick down cable is mounted to the carburetor, or, in the case of fuel injected vehicles, the throttle body. It runs from the butterfly arm on the carburetor down to the side of the transmission, where it attaches to an arm that allows the transmission to shift gears.

How do I know if my kickdown cable is bad?

Symptoms of a Bad or Failing Kickdown Cable

1. The transmission shifts hard. An automatic transmission has multiple parts that are engineered to produce a smooth transition from one gear to another.
2. The car shifts early and fast.
3. The transmission shifts slow and late.

What is a transmission detent?

A transmission shift control has a detent mechanism to provide a shift effort so that the operator has a sense of feel during shifting between ranges. During a manual shift between reverse and park, the shift effort or “detent feel” is normally higher than the effort occurring during manual shifts between other ranges.

How do you kick down an automatic transmission?

Kick-down is used when maximum acceleration is needed, such as for overtaking. When the accelerator pedal is pressed all the way to the floor (beyond the position normally regarded as full acceleration) a lower gear is immediately engaged. This is known as kick-down.

Do you need a transmission kickdown cable?

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. On transmissions designed around a TV cable, its presence is mandatory.

How do you adjust a transmission cable?

Check the shift cable where it attaches to the transmission shifter arm. Use your wrenches to place tension or remove tension on the cable until it forces the shifter on the engine block into neutral as well. Then tighten the locking screws to keep the cable sleeve from moving in the future.

What does the modulator valve on a transmission do?

The modulator valve is attached to the intake manifold with a vacuum line. It senses intake manifold vacuum and shifts the transmission accordingly: When you press down on the gas pedal, the throttle plate opens and the vacuum is reduced. The modulator valve will cause the transmission to downshift.
