What kind of lubricant is used for the gear shift ball head?
2 Answers
Automobile gear shift uses transmission oil (also known as gear oil or transmission fluid). Here is the relevant introduction: 1. Function: Transmission oil is a lubricant that keeps the gear system clean, ensuring normal operation of the transmission and extending the service life of the transmission device. 2. Characteristics: Transmission oil can basically be used in automatic transmissions on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, structure, etc. Therefore, the original manufacturer has its own specified special transmission oil. Different transmission oils are one of the reasons that affect the quality of gear shifting.
I previously did some DIY maintenance on the shift knob ball joint, and found that white lithium-based grease works the best. This stuff is quite thick, so it won't splatter everywhere like engine oil, and it's also heat-resistant. The area under the steering wheel gets really stuffy in summer, where regular grease might just melt. Before applying, use an old toothbrush to clean off any dirt on the ball joint surface—otherwise, the grease mixed with sand particles could accelerate wear. Remember not to apply it too thickly; a thin layer is enough, or else the shifting might feel sticky. The one I used even had a bit of Teflon in it, and after more than two years, the shifting is still smooth—way better than regular grease.
