Can I run a Turbo 350 without a kickdown cable?

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.

What does the detent cable do?

One of the many essential parts of a carbureted or fuel injected vehicle is a transmission kick down cable. The transmission kick down cable works to shift the transmission to a higher gear automatically when the engine is revved or otherwise accelerated.

What does the vacuum modulator on a Turbo 350 do?

The vacuum modulator is a vital component of automatic transmissions. It tells the transmission what kind of load is being put on it, allowing the transmission to react with the proper line pressures and shift points.

How do I know if my kick down 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.

Is kick down bad for car?

Do you need TV cable on TH350?

Premium Member. The TH350 uses vacuum for upshifts, and the cable for kickdown. You don’t have to have the detent cable hooked up on a TH350 for the transmission to function, only if you want to have passing gear. If it’s left disconnected, simply drop it down into 2nd gear manually and upshift it manually.

How do you adjust shift points on a th350?

Get a small flat head screwdriver,go to the passenger side of the transmission. Unhook the vacuum line on the modulator and screw the adjustment screw inwards in 2 turn increments. Screwing it all the way in will give you very hard shifts and will feel very uncomfortable when it shifts at higher speeds.

What happens if kickdown cable breaks?
