Automatic transmission shift cable
The shift cable in an automatic transmission (AT) is the component that connects the shift lever inside the vehicle to the shift lever on the automatic transmission. It is responsible for transmitting the movement of the gear lever to the automatic transmission, which leads to gear changes.
Design:
* Cable: Flexible metal or plastic cable with a protective sheath.
* Ends: At one end the cable is attached to the gear shift lever, and at the other – to the gear shift lever on the automatic transmission.
* Lugs: Metal lugs on the ends of the cable that attach to the gear shift levers.
* Tensioner: An adjustment mechanism that allows you to adjust the tension of the cable.
Function:
When the driver moves the gearshift lever, the cable transmits this movement to the gearshift lever in the automatic transmission. This forces the hydraulic control unit (HCU) inside the automatic transmission to open or close the corresponding channels, shifting gears.
Care and maintenance:
* Check the cable tension regularly and adjust it if necessary.
* Lubricate cable ends and attachment points.
* Replace the shift cable if worn or damaged.
Signs of malfunction:
* Difficulty changing gears.
* Gears do not shift smoothly.
* The automatic transmission does not shift to a lower gear under load (for example, when going uphill).
Replacement:
Replacing the shift cable is a relatively simple task that can be done yourself or at a garage. To do this you need:
* Disconnect the cable ends from the gear shift levers.
* Remove the protective shell.
* Remove the old cable.
* Install a new cable.
* Install the protective shell.
* Connect the cable ends to the gear shift levers.
* Adjust the cable tension.
