Can the Transmission Mileage Be Adjusted?

Car odometers can be adjusted. Additional information is as follows: 1. Introduction: The speedometer indicates the vehicle's speed in km/h (kilometers per hour). The car odometer actually consists of two meters: one is the speedometer, and the other is the odometer. The car odometer is generally located directly in front of the driver's position. 2. Principle: Traditional speedometers are mechanical. A typical mechanical odometer is connected to a flexible shaft, which contains a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer housing to rotate. The housing is connected to the pointer, and the pointer is set to zero by a hairspring. The speed of the magnet's rotation causes changes in the magnetic field strength, disrupting the balance and thereby moving the pointer.

As someone who frequently deals with used cars, I've found that tampering with the transmission mileage is technically feasible, but it's absolutely unethical. Some repair shops use OBD devices to rewrite the data in the vehicle's computer, turning a car with hundreds of thousands of kilometers into one with just tens of thousands. But this is illegal, my friend! The 'Consumer Rights Protection Law' clearly states that odometer tampering constitutes fraud, and if caught, you could be liable for three times the car's value. What's even worse is that a car with a tampered odometer can lead to misjudging its condition—for example, a transmission that should have been overhauled might suddenly fail on the road. Last time, I met a guy who bought a car with a tampered odometer, and the transmission completely broke down after just two months, with repair costs amounting to half the price of a new car. I recommend checking maintenance records and getting a third-party inspection to avoid such risks.

A master technician with 10 years of transmission repair experience tells you: Odometer tampering is entirely possible nowadays, it can be done in just half an hour using professional diagnostic equipment. But this is like giving a car cosmetic surgery - while the exterior appears younger, the internal organs remain aged. Transmission wear directly determines lifespan. A car with 200,000 km adjusted to show 50,000 km will still have worn-out components like oil seals and gear sets. The worst part is buyers spending new car money to repair an old vehicle - I've handled several tampered cars whose transmissions were full of metal shavings when opened. My advice: check interior wear when inspecting a car - steering wheel and pedal marks tell a more truthful story than the odometer.

The biggest fear when buying a used car is encountering one with a rolled-back odometer. The transmission mileage can indeed be altered through software, a practice commonly found in rebuilt cars or those involved in major accidents. A friend of mine fell victim to this—the car showed 60,000 kilometers at purchase, but later the original records at a dealership revealed 150,000 kilometers. Rolling back the odometer hides crucial maintenance cycles, causing missed deadlines like transmission fluid changes, which in my friend's case led to seized gear sets. Nowadays, professional inspection services are available in the market; spending a few hundred dollars to check the vehicle's full ECU data can help avoid major pitfalls. Keeping the inspection report also serves as evidence for consumer rights protection.

What to do if ETC payment is missed?

Missed ETC toll payments on highways can be settled later. Generally, after the first failed deduction, the staff will send a text message to the vehicle owner to remind them of the failed payment and attempt another deduction within the next 2-3 days. If both deductions fail, the ETC account will be considered overdue, and normal passage through highway ETC lanes will be restricted. For postpaid users signed with a bank, you can directly go to the bank counter to pay the outstanding toll. For prepaid users or bank-signed prepaid users, you can recharge at an ETC service center to restore the whitelist status. Normally, normal passage will resume after 48 hours. In future use, ensure that your bank card or ETC account has sufficient balance to cover ETC toll fees. Methods for settling missed payments: If you passed the station without paying, promptly find staff at the manual toll lane to settle the payment. You can make a secondary payment by swiping a card or paying in cash. If you have already left the toll station, the previous toll can be deducted together during your next exit. Call the ETC customer service hotline for assistance. Consequences of not settling payments: The system will flag the vehicle for toll evasion, adding the vehicle's ETC to a blacklist. The vehicle will be barred from all national highways and charged the maximum distance toll. According to the "Guidance on Financial Services Supporting Toll Road System Reform" issued by the People's Bank of China and the China Banking and Insurance Regulatory Commission, ETC arrears exceeding 30 days will be reported to credit bureaus. If the ETC is linked to a credit card, even a one-day delay can affect personal credit. Precautions for using ETC cards: Before using ETC at a toll station, ensure the ETC card is correctly inserted into the OBU. Driving vibrations may loosen the card, so check regularly and reinsert if necessary. ETC cards are vehicle-specific and cannot be swapped after binding. Before using ETC, check the toll information displayed on the dedicated lane sign. Recharge promptly if the balance is insufficient. If the barrier does not lift when passing through an ETC lane, follow the instructions of toll station staff or switch to a manual toll lane. If the ETC lane is temporarily closed, use the manual toll lane for payment. The speed limit for ETC lanes is 20 km/h, and maintain a distance of at least 5 meters from the vehicle ahead. If an ETC vehicle collects a toll card at a manual lane, it must exit via a manual lane, not an ETC lane.

How Much Does a 20-Horsepower Four-Wheel Vehicle Weigh?

20-Horsepower four-wheel vehicles with their body weight typically weigh around two tons. You can weigh it at a weighbridge for a more accurate and quick measurement. The weight of a four-wheel vehicle may change over time with usage. Below is an introduction to the weight standards of four-wheel vehicles: 1. Self-weight: The self-weight of small agricultural four-wheel vehicles mainly depends on the vehicle's structure. Taking the first-generation Luoyang Dongfanghong small four-wheel vehicle as an example, its self-weight reaches 3000 kilograms. Agricultural four-wheel vehicles are generally diesel-engine vehicles, similar to manual transmission cars, so a C3 or higher driver's license is required to operate them. 2. Agricultural transport vehicles: Agricultural transport vehicles refer to the general term for trucks used in agricultural transportation, mainly including vehicles specifically designed for agricultural transportation and modified ordinary agricultural transport trucks. Agricultural transport vehicles usually use diesel engines, and four-wheel drive models are equipped with differential locks, off-road tread tires, or low-pressure wide-section tires. 3. Advantages of agricultural transport vehicles: The advantages of agricultural transport vehicles include good driving visibility, safe and convenient operation, simple structure, and low cost. Additionally, agricultural transport vehicles can be modified, such as using detachable canvas canopies to convert them into ordinary trucks.

Why don't 4S stores issue invoices at the end of the month?

Here are the reasons why 4S stores do not issue invoices at the end of the month: 1. 4S stores need to settle accounts: Every company has a financial settlement deadline, and generally, 4S stores will submit the invoices for the current month to the tax authorities by the 25th. Therefore, after the 25th, they stop issuing invoices to prepare for account settlement. Consumers who come to buy a car will have to wait until the next month to get the invoice. 2. The 4S store has completed its sales target: Automobile manufacturers usually have a strict management system for 4S stores, and they assign sales targets to each dealer, conduct irregular spot checks and evaluations, and use these as the basis for rebates to the 4S stores. Therefore, when a 4S store has already met its sales target for the month, the store may not want to sell more cars, as exceeding the target could lead to an increased target for the next month. By postponing the extra sales orders to the next month and issuing the invoices then, the store can make the next month's target easier to achieve. Hence, the 4S store may require waiting until the next month to issue the invoice. 3. The monthly invoice quota has been used up: Different businesses have different invoice limits. Larger 4S stores generally have higher invoice limits, while smaller ones do not. So, once a store has used up its invoice quota for the month, it may have to wait until the next month to obtain new invoices before it can issue them.
