How would incorrect adjustment of the throttle cable affect transmission operation?
When the throttle valve cable is out of specification, the transmission can shift early, shift late or not shift at all. Warning: Improperly adjusting the throttle valve cable can cause extensive damage to the transmission.
How tight should the throttle cable be?
The accelerator cable tension is usually set so that 2-3mm of free play is present in the throttle grip. Once the correct tension has been applied, the lock nuts should be snugged and any dust covers should be slid back over the adjusters. Cables can be adjusted using the appropriate size wrench.
What does adjusting the throttle cable do?
A throttle cable has some advantages over a throttle-by-wire system. Loosening these nuts allows you to slide the cable backward or forwards to adjust the tension. Once you’ve adjusted the throttle cable—your owner’s manual typically lists a specific amount of deflection—simply tighten the nuts back down.
What are the symptoms of a loose throttle cable?
Signs of a bad accelerator cable
- The pedal feels stiff or hard to depress.
- The pedal sticks and does not release normally.
- There is slack in the pedal’s movement.
- There is a rough or abnormally low idle.
- The engine stalls.
- There is a delay in response when you push the pedal down.
What happens if your throttle cable breaks?
When the gas pedal is pressed, the cable is pulled and opens the throttle. If the cable breaks, or comes out of adjustment far enough, it can affect the drivability of the vehicle to the point where the car will not be drivable until the problem is addressed.
Should I tighten my throttle cable?
The tightness of the accelerator, or throttle, cable on any vehicle is important. If the cable is tightened too much, the car will not idle properly and consume fuel quickly. If the cable is too loose, the car will respond slowly when you press the gas pedal.
How do I know if my throttle cable is bad?

Why is my throttle cable loose?
1. Improper cable adjustment and slow acceleration response. When there is excess slack or the cable is too tight, this can cause intermittent delays in throttle response relative to pressing down on the accelerator pedal.
When do you need to adjust the throttle valve cable?
The throttle valve cable is used to control the line pressure, downshifting and the feel of the shifting. When the throttle valve cable is out of specification, the transmission can shift early, shift late or not shift at all. Before the throttle valve cable can be adjusted, the transmission must be in good working order.
How to adjust throttle cable on 700R4 TV?
700R4 – 200-4R Throttle Valve Cable Instructions-700R4 TV Adjustment #1. The button that the cable hooks to at the carburetor or throttle body must have approximately 1 and 3/32-inch radius… #2. Looking at the throttle shaft lever from the left side at idle position, approximately 33% of the
What happens when the cable is not adjusted on a 700R4?
The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.
