What are the symptoms of a broken manual transmission shift cable?

[VonLuna]

Manual transmission shift cable damage manifests as affecting normal gear shifting. Before breaking, gears may be difficult to engage or may not fully engage. You can open the shift box to see the shift cable head detached from the gear head, resulting in an inability to shift gears. Adjusting the shift cable: Adjusting the shift cable requires two people to complete. During adjustment, one person shifts gears while the other adjusts. When pushed into the corresponding gear, do not release until the other person has adjusted the shift cable, then proceed to adjust the next gear until all cables are adjusted to the proper position. Solutions for a frozen shift cable: If the shift cable is found to be frozen, you can first start the car and use the heat generated by the engine at idle to thaw the shift cable. This method is the simplest way to thaw. Alternatively, if the shift cable is frozen, you can remove it, then use warm water to melt the ice on the shift cable. Afterward, spray an appropriate amount of WD-40 as a lubricant, or take a small amount of engine oil, soak the entire shift cable for a while, and then reinstall the shift cable.
