Before we jump into the service, it is essential to know about the shift selector cable and the way it operates. The shift selector cable works like a connector to the gear shifter, which is located on the a floor mounted console or on the steering column, to an automatic transmission. In the most usual scenario, the cable is made out of steel and is shielded from outer elements by a plastic case. On each of the gear shift cable end, rubber or nylon bushings are used to permit cable movement and vibration. In some applications, the cable is flexible, meaning it can be stretched while in use.
The right time for a shift cable replacement
- Zero response to gear shift change. If there is a situation comes when the cable breaks down, or the cable ends detach, shifting won’t be possible at all. On few occasions, it is a just a matter of changing the cable end bushing. On other occasions, the complete cable assembly must be revamped.
- Shift Indicator does not align with the gear settings. An extended shifter cable may cause the vehicle to be in a different gear than the one you selected. If adjustable cables are present, you might not have to buy a set of new cable.
- Inefficient to take out key from ignition plug. In the presence of a broken cable, or if the cable end has detached, you may face difficulty in positioning the vehicle in the parking area (by using the parking mode). For such an event, the key usually cannot be removed from the ignition.
How mechanics replace the shift cable selector?
- The cable ends is primarily examined to figure out the exact issue — is it’s a broken or a lost bushing. Sometimes, nylon bushing placed at the cable’s transmission end cracks. If the mechanic is able to see that is the only issue, he will bring in a new bushing and re-attach the cable.
- If the cable is broken, or extended to an unprecedented level, adjusting does not prove to be effective. For such instances, the car is uplifted and assisted by steel jack stands.
- The shift cable needs to be detached on each end, and also at the transmission and shifter base at the same time.
- The newly fitted cable is routed and the bushings are applied, or in case of a mechanically-connected set up, nut and bolts are properly tightened to attach the cable to the shift lever on the transmission.
- The vehicle is lowered and the shift cable is examined thoroughly for proper adjustment and functioning.
