Transmission mileage can be altered. Here is the relevant information: 1. Vehicle odometer: There are two types of vehicle odometers for calculating mileage - mechanical and electronic. Mechanical odometers are typically modified by reversing the mechanism. Electronic odometers require ECU flashing, which is more technically demanding but quicker, though it comes with a fee since the ECU cannot be flashed arbitrarily. 2. Basis: The odometer displays the distance the vehicle has traveled, serving as a basis for assessing vehicle quality and maintenance. 3. Classification: Depending on the transmission structure, transmission fluid is categorized into manual transmission fluid and automatic transmission fluid.

The term 'transmission mileage' actually refers to the tampering issue with the vehicle's total odometer reading, which typically pertains to the overall driving distance of the entire vehicle, as the transmission itself does not have an independent mileage recording system. I can tell you that technically it is possible to alter this, as some unscrupulous dealers may use OBD-II interfaces and specialized tools to adjust the dashboard numbers, but this is absolutely illegal and constitutes fraudulent behavior. I've seen cases where such modifications easily trigger error codes in the vehicle's computer, leading to abnormal transmission performance or failure to report faults. More importantly, if discovered during a used car sale, the buyer can sue you, resulting in hefty fines or even imprisonment, and you may also lose vehicle warranty eligibility. Therefore, I recommend keeping everything original and not risking short-term gains. Maintaining good maintenance records is the right approach—document every transmission fluid check and part replacement in the log. This ensures long-term safety.

The idea of altering odometer readings might sound tempting, but I must warn that it's outright fraud with serious legal consequences. In most countries, mileage tampering is a criminal offense that can lead to fines, lawsuits, or credit stains affecting one's entire life. More importantly, it conceals the vehicle's true wear condition. As I often remind friends, transmissions require maintenance every 10,000 kilometers – falsified mileage may cause owners to underestimate risks, leading to major repairs or even accidents. Ethically, this undermines the integrity of the used car market. I advocate checking service manuals and repair histories when buying/selling cars. Honestly recording actual mileage isn't just legal – it preserves vehicle value and safeguards everyone's finances and safety.

The transmission mileage cannot be altered as a separate record; usually, it's the vehicle's total odometer that gets adjusted. This practice is illegal. While technically possible, the risks are too high—it's easy to get caught, such as when professional scanners detect inconsistencies in historical data. The consequences? Not only could buyers sue you for fraud when selling the car, but insurance companies might also raise premiums or deny accident claims. What worries me more is the safety aspect: masking the actual wear and tear of the transmission can lead owners to delay maintenance, risking critical failures. So, steer clear of such practices. Playing by the rules is the safest way to enjoy worry-free driving.
