What are the common faults of manual transmission?
2 Answers
Common faults of manual transmission include: 1. The gear lever jumps back to neutral while driving; 2. Gear disengagement occurs; 3. Inability to engage gears normally. The functions of the transmission are: 1. To change the transmission ratio to meet the traction needs under different driving conditions; 2. To enable reverse driving; 3. To interrupt power transmission to the drive wheels when the engine starts, idles, the car shifts gears, or needs to stop for power output. Maintenance methods for the transmission: 1. Frequently check the fluid level; 2. Do not skip gears when upshifting; 3. Do not force the transmission into neutral; 4. Do not shorten the idling warm-up time; 5. Avoid gear grinding when shifting.
After driving manual transmissions for so many years, I've found clutch issues to be most common. Problems like slipping or difficulty shifting gears often indicate worn clutch discs, while hydraulic system leaks can make the clutch pedal feel stiff. Loud transmission noises such as whining or clicking usually point to bearing failures. Worn synchronizer rings make downshifting particularly difficult, especially in older vehicles. While less frequent, gear damage (like chipped teeth or breakage) can be serious, requiring major repairs. Aged or insufficient transmission fluid accelerates wear - I change mine every three years. Loose shift cables cause imprecise gear engagement, and gentle driving habits can extend component life. Address any unusual noises or vibrations promptly to prevent major failures.
