It is common practice in the current models and some older models to make use of cable to link the shifter handle to the transmission line of vehicle. Most of the automatic transmission vehicles are equipped with a single transmission shifter cable, unlike the manual ones, where there are two shifter cables installed. Irrespective of the type of transmission, the functioning of the shifter cable works the same. However, the symptoms of the transmissions have no similarities at all.
The significance of a shifter cable
Automatic transmissions come with a factory-fitted single shift lever, which is connected to the manual valve in the valve transmission body. The lever works on a push-and-pull mechanism on a single surface but into a variety of available positions as the shifter handle is moved inside the car. Manual transmissions come equipped with two shift levers, one is used for vertical movement and te other for facilitating horizontal movement of the shifter assembly.
The lever that is placed horizontally is pushed/pulled by one cable, that slides across a single plain surface with three different positions. The vertically positioned, which is the second lever, usually moves with the shifter assembly on a up-and-down motion with regards to the transmission. When the shifter moves toward the front or rear of the car, the cable also moves along the horizontal lever. Moving your shifter on any given position attracts the other cable, that moves the shifter assembly up and down. If your vehicle is fitted with a six-speed manual transmission box, you may find your vehicle to have a third shift cable that can engage a lock-out lever. This cable is primarily used when a button is pressed to engage reverse.
Reasons for a cable failure
Quite often, it is seen that the reason for a shift cable’s failure is due to excessive stretching. It is prevalent in vehicles that come with manual transmission systems because when the shifter is moved more frequently, you forget about setting it and completely forget about it as you with an automatic transmission vehicle. The shifter cables are also vulnerable to break, or under some instances can bend quite easily, preventing the shift lever to make any kind of motion on the transmission to get into the correct position for the chosen gear.
Symptoms of a bad automatic transmission shifter cable
- If the vehicle’s gear position indicator in not digital, you will find that the indicator needle does not align correctly with the gear you are actually in
- If the cable stretches too far, it degrades in quality, which may prevent you to engage in a proper manner with the selected gear
- If the cable is broken, it would be really difficult to move the shifter into a desired position, however, the transmission will remain in the same gear
