Okay, you are about to replace your old car’s engine, and you’re thinking if you also need to replace the transmission because you need the mileage to drop? Let’s look at this, does the odometer reset with a new transmission? It practically does not.

The odometer in vehicles is not associated with the transmission system or even the engine. It is more like a standalone system in every vehicle, but it still connects to the wheels. The odometer does one major function; to read the mileage of a vehicle.

Transmission change can improve your engine’s performance and make your car drive smoothly, but it definitely doesn’t have anything to do with resetting mileage reading.

Does The Odometer Reset With a New Transmission

Firstly, it is ideal to understand how the odometer works. The odometer calculates its reading as the wheels of your vehicle rotate. So, the more you drive, the higher the odometer reading. When your engine is faulty or the transmission is failing, it won’t affect the odometer reading.

That said, when you pull out the transmission on your car and install a new one, it’s more like nothing changed; the moment you start the car and keep driving, the odometer would resume reading from where it stopped previously.

A new transmission would not affect your vehicle’s mileage reading because the transmission system does not control the odometer.

When happens when you get a new transmission is that your car would start functioning as supposed because an old, failing transmission can cause a vehicle not to function properly.

But then, some people do change the odometer reading of their vehicle; thus, resetting the mileage to zero, or lesser numbers. This is quite possible, but it can only be done manually – not by installing a new component (engine, transmission, or wheels).

Note: Mileage only counts when the car is the motion. If your car idles for many hours, the mileage reading on the odometer won’t shift one bit. But the moment the wheels move, the number on the odometer would increase, and keep increasing as the vehicle remains in motion.

What Can Reset The Odometer?

Practically nothing. There’s nothing you’d change in your car to alter the mileage reading on your odometer. But some mechanics and auto experts know of a manual way to reset mileage readings. While this is not advisable, some drivers do it, especially when they intend to sell the vehicle.

Well, changing the odometer reading would not practically affect your old car’s value. Smart buyers would always find out you did that, and that could be an obvious red flag for them to back off the deal.

Conclusively, for the question, “does the odometer reset with a new transmission?” The simple answer is NO. You can only reset the odometer manually, and this is not even advisable as it can make buyers not believe whatever else you have to tell them about the car at the point of sale.

Notwithstanding, a new transmission can boost your engine’s performance, which can lead to a general boost in how your car drives. It’s advisable to get a new transmission if the old one is badly damaged.
