To find out the transmission number (automatic transmission) by VIN number, follow these steps:
1. Go to the online VIN decoder website.
Here are some popular sites:
* [Decoder VIN](https://decodervin.com/)
* [VIN Decoder](https://www.vindecoder.net/)
* [My VIN Decoder](https://www.myvindecoder.com/)
2. Enter the VIN number in the search field.
3. Click “Decode”.
4. Find the “Transmission” section.
This section must indicate the automatic transmission number. This is usually a combination of letters and numbers, such as F4A51 or 6F35.
Note:
*Some sites may only show general information about the transmission, such as the type (automatic, manual, etc.), but not the specific number.
*Not all sites offer VIN decoding feature for free use. Some may charge a small fee for this service.
