What are symptoms of a broken gearbox? Pay attention to following symptoms
1. Vehicle transmission locked
Status: When car is running normally, gas pedal speed is high, but speed is very low. When brake speed falls to a certain level, it will stop falling. When I switch to a manual transmission, I find that I can no longer upshift or downshift when shifting into gear. So prone to accidents!
Reason: Vehicle transmission input and output signals are incorrect, or components themselves or wiring are not in order, and sometimes there are problems with transmission computer and other system computer communications!
2. Vehicle does not move when in gear
Situation: After car is started, gear shifts to D or R and car does not respond when handbrake is released. Manually shifted to 1st gear, when clutch is released, car does not go. Do not get annoyed at this time, you need to be more calm and calm, try a few more times, if car still does not drive, you can call for help!
Cause: This could be caused by a damaged gearbox or reverse clutch input shaft, or a damaged D/R brake. This can be caused by a transmission oil leak, a severe lack of transmission oil, or a connection between shift lever and hand valve rocker or cable so that hand valve remains in neutral or park position. gear earth!
3. Shock when shifting
Condition: When car is running normally and shifting gears, power unit torque transmission changes, causing reflection of vibration or noise in car, that is, shift is not smooth, such as car stops and gear shifts. The handle is still shaking!
Cause: The vehicle's gearbox may be too dirty, causing valve body to jam. Just change gear oil!
4. Abnormal noise in gearbox
Condition: I heard an abnormal transmission noise while driving.
Reason: damage to bearings and transmission components or too low accuracy of spare parts!
5. Shift time too long or too short
Status: Usually, automatic transmissions also have a certain shift speed and vehicle speed. If you feel that gear is upshifting too fast while driving, it will directly affect vehicle speed!
Reason: Gear ratio problem
6. Vehicle slippage
Status: While driving, while refueling, I heard sound of engine idling, and vehicle speed did not increase, and I feel that acceleration is weak! If you continue driving, this will cause serious damage to gearbox, and it may even be scrapped!
The above malfunctions must be corrected as soon as possible and must not be ignored, otherwise consequences will be very serious! The price will also be very high!
