Transmission failure reasons: Transmission temperature is too high; Transmission fluid not replaced for a long time, leading to fluid deterioration; Transmission torque converter lock-up function failure; Transmission cooler clogged or cooling fins bent; Water ingress into transmission; Hazards of not changing transmission oil: 1. Damage to transmission shift control mechanism; 2. Abnormal wear of transmission gears and clutch plates; 3. Affects normal operation of transmission, leading to valve body damage. Transmission oil and engine oil are different. Although both serve lubricating purposes, they perform different functions and should not be confused. Differences: Engine oil is the lubrication oil for the engine system, possessing certain anti-oxidation, anti-wear, and anti-corrosion properties. Transmission oil mainly maintains cleanliness of the gear system and extends the service life of internal transmission components. Because transmissions and engines have different structures and operating environments, transmission oil cannot be used as engine oil, nor can engine oil be used as transmission oil.

Will changing tires outside the 4S store affect the warranty?

No, changing tires does not void the warranty. Here are some precautions for tire installation: 1. Balancing machine test: After tire removal and installation, use a balancing machine to test the balance of the tire and wheel hub during movement to ensure smooth driving and avoid shaking. 2. Check tire pressure: Regularly check tire pressure, as both underinflation and overinflation can pose a risk of tire blowouts. 3. Wheel alignment: After changing tires, perform a four-wheel alignment to maintain stable straight-line driving and easy steering, reducing tire wear to prevent potential hazards.

What Causes Oil to Spray from the Exhaust Pipe?

Oil spraying from the exhaust pipe is caused by: 1. Faults in the piston, cylinder liner, piston pin, or piston rings. In this case, the damaged parts need to be identified and replaced. 2. Severe wear or poor sealing between the valve stem and valve guide, resulting in excessive clearance, which leads to oil leakage. Prompt repair is necessary. Engine oil is the lubricant used in engines. Composed of base oil and additives, it serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is often referred to as the 'blood' of the car.
