How does a kickdown work?

How does a kickdown work?

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. If the accelerator is released from the kick-down position, the gearbox automatically changes up.

How does a Turbo 350 kickdown cable work?

The kickdown function of General Motors vehicles equipped with the Turbo 350 automatic transmission is perhaps better known as “passing gear.” As the accelerator is depressed, the throttle lever on the engine is drawn back by a cable, which in turn pulls another cable attached to the transmission, causing it to …

What is a passing gear?

A gear in an automatic transmission that allows the passing of a slower moving car more easily. It is activated when the gas pedal is sharply depressed.

Do you need a kickdown cable on a Turbo 350?

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. “Kickdown” and “TV” cables aren’t really the same thing.

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. You must install a true TV cable with the correct throttle-lever pivot geometry and then adjust it properly or you will burn up the trans!

What does the transmission kickdown cable do?

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.

Do I need a kickdown cable?

Is the A-518 a 5 speed transmission?

However, the A-518 is based on the A-727 and they share some things in common, which makes this conversion relatively easy and an economical alternative to converting to a different rear end or to a five-speed manual transmission.

What happens when you go from first to third gear on an E4OD?

You will want to make sure that your truck isn’t actually skipping second gear and going right to third. When the intermediate clutch fails on an E4OD it causes it to stay in first gear until third gear is commanded and then it will shift from first to third. Going directly from first to 3rd will cause a harsh shift.

Why does my transmission increase line pressure in third gear?

If the computer detects slippage in the transmission it will increase line pressure to maximum to try to stop the slip and protect the transmission. This results in a very firm shift. The problem with third gear is probably why the line pressure has been increased. To top

How does a solenoid hook up to a transmission?

When the linkage hits WOT, this completes the circuit to connect the transmission to full system voltage. This electrical input powers up a solenoid in the transmission that accomplishes the same results, with higher line pressure and a signal to downshift the transmission.
