Does a Turbo 400 need a kickdown cable?

Instead of a linkage or cable, the TH400 uses an electrical switch that is most often mounted on the carburetor. The 12-volt connection is a single spade connector just above the oil pan rail on the driver’s side about halfway back–at least that’s where it is on my TH400.

What is automatic transmission kick down?

Kickdown can be used when maximum acceleration is needed, e.g. when passing. When the accelerator pedal is depressed all the way to the floor (past the normal full accelerator position), the transmission will automatically engage kickdown, i.e. immediately shift down to a lower gear.

Where is the kickdown switch on a TH400?

When the Turbo 400 began reaching production models in the late ’60s, its kickdown switch was mounted on or near the carburetor. It was, however, relocated to the passenger compartment and mounted on the throttle pedal in later years.

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.

Why would you use kickdown?

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 all cars have a kickdown switch?

Do all Automatic Cars have Kickdown? Almost all automatic cars have the kickdown feature. Earlier automatics, or basic modern automatics simply have a switch that’s activated by the driver pressing the accelerator pedal to the floor.

When should I use kickdown?

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.

Do all automatic cars have kickdown?

Does a Turbo 400 have a passing gear?

The TH400 transmissions have an electric passing gear switch (kick down switch). This switch is located just above the gas pedal. The transmission will never work correctly without this switch. This switch will fit your car or truck if your make and model was available with a TH400 transmission.

How does a Turbo 400 downshift?

When the throttle linkage reaches a specific point, the cable triggers a mechanical detent valve inside the transmission–allowing it to shift into a lower gear. The Turbo 400 uses an electric switch to trigger a detent solenoid on the valve body to produce the same effect.

Do I need the kickdown cable on a TH350?

See all 8 photos Other than the convenience of automatic downshifts into passing gear at highway speeds, there’s no real need for a simple kickdown cable on those transmissions like this TH350 that have a vacuum modulator.

What does the TV cable do on a Turbo 350?

The TV cable is attached on one end to the throttle linkage and on the other end to the transmission. As the throttle is depressed, the cable is pulled, causing progressively later upshifts at higher throttle positions.

Do you have to hook up kickdown cable th350?

the “kickdown” is NOT that. It’s a TV cable, which operates the Throttle Valve inside the transmission, and is NECESSARY to be installed and PROPERLY adjusted so you don’t burn up the transmission. It has nothing specifically to do with the transmission dropping down a gear when you mash the pedal.

When would you use kickdown in an automatic car?

Why would you use kick-down? Explanation: The action of sharply pressing the accelerator to the floor (kick-down) will send a signal to the transmission to select a lower gear. This is useful when wanting to accelerate briskly, such as when overtaking another vehicle.

Is kick-down bad for car?

No, unless the engine speed increases excessively (in an emergency you will accept this for braking). Just about any vehicle will deny kickdown if your road speed is too high “at that time”. It will put stress on your drivetrain, but this should be well within design parameters.

Is Downshifting bad for automatic transmission?

Never use the automatic transmission to slow down This practice is not acceptable in automatic transmissions because a forced downshift at high-engine RPMs can result in excessive transmission wear, specifically to the clutch friction plates and the transmission bands.
