Transmission API: Get Detailed Transmission Specs by VIN
The Vehicle Transmission API delivers transmission identification, transmission codes, gear ratios, transfer case information, and drivetrain-related specifications for all vehicle types from 1981 to present.
Find the Right Transmission Without the Research
Everything needed to retrieve, access, and work with track width and wheelbase data in one API.
The Problem
Too Many Transmission Configurations
The Solution
One Lookup. Detailed Transmission Data.
See the Transmission Data for Yourself
Explore real-world transmission specifications before getting started. Test supported VINs, review sample responses, and see the transmission information available across millions of vehicle records.
How the Transmission API Works
The Transmission API makes it easy to retrieve transmission specifications from a supported VIN or vehicle record.
Step 1: Identify the Vehicle
Provide a supported 17-character VIN or vehicle details including Year, Make, Model, and Trim.
Step 2: Retrieve Transmission Data
The API identifies the vehicle and returns available transmission specifications for its configuration.
Step 3: Use the JSON Response
Receive transmission data in a consistent JSON format.

Detailed Transmission Identification & Specifications
Transmission type alone doesn’t tell you much about how a vehicle actually performs, tows, or gets serviced. Depending on the vehicle and configuration, this API can return the following:
| Data Group | Available Fields |
|---|---|
| Transmission identification | Type, description, transmission code, number of forward speeds, reverse speed count. |
| Drivetrain integration | Drivetrain configuration and final-drive axle ratio. |
| Gear ratios | First through tenth gear where applicable, plus reverse ratio. |
| Transfer-case details | Transfer-case model, high-range ratio, low-range ratio, PTO information where applicable. |
| Vehicle context | VIN, year, make, model, trim, and other vehicle-identification fields returned with the lookup. |
| Data availability | Returned-field indicators or availability metadata, where supported. |
Make engine specification lookups faster, simpler, and easier to automate.
- NOTE: Not every vehicle will have values for every field. Gear-ratio and transfer-case detail tend to be more sparse for older or lower-volume configurations than basic transmission type and speed count, which are available for nearly all supported vehicles. The response returns the transmission information available for the identified vehicle configuration.

When Do You Need the Transmission API?
If transmission data is all your application needs, an API focused on transmission data is the best option. For broader vehicle information, the Vehicle Specifications or VIN Decoder API may be a better fit.
If you need... |
Use This API |
|---|---|
| Transmission type, gear count, ratios, and transmission details | Transmission API |
| Transmission plus engine, dimensions, performance, features, and other specs. | Vehicle Specifications API |
| Vehicle identification plus engine, transmission, drivetrain, and core vehicle data. | VIN Decoder API |

Vehicle Databases Transmission API vs. Manual Lookup
Finding transmission information manually can mean checking manufacturer specifications, build information, parts catalogs, or other vehicle databases for each configuration.
The API turns that research into a repeatable lookup your application can perform automatically.
| Transmission API | Manual Lookup | |
|---|---|---|
| Vehicle Identification | VIN or vehicle lookup | Search multiple sources |
| Transmission Matching | Exact vehicle configuration | Manual verification required |
| Gear Ratios | OEM ratio data | Research and manual entry |
| Transfer-Case Data | Included when available | Separate lookup required |
| Transmission Codes | Returned with the vehicle | Manual decoding required |
| Data Consistency | Standardized response format | Varies by source |
| High-Volume Lookups | Scales from 1 to millions | Effort grows with volume |
| Software Ready | Clear JSON output | Manual data entry |

FAQs on Vehicle Transmission API
What information does the Transmission API return?
The API can return transmission type, transmission code, description, number of speeds, gear ratios, reverse gear ratio, final-drive axle ratio, and available transfer-case information.
Can I look up transmission specifications by VIN?
Yes, you can look up transmission specifications by VIN, as the API supports 17-character VIN lookups for supported vehicles.
Can I search for transmission data without a VIN?
Yes. You can use year, make, model, and trim to request available transmission specifications.
Does the API identify automatic and manual transmissions?
Yes, the response you get from the API includes the available transmission type and description for the identified vehicle configuration.
Does the API provide the number of gears?
Yes. The response can include the number of transmission speeds.
Does the VIN directly contain the transmission type?
Yes, but not as a simple fixed field for most vehicles. VIN decoding uses the VIN together with vehicle/build data to identify specifications such as transmission configuration.
How is this different from the Vehicle Specifications API?
The Transmission API focuses specifically on transmission-related information. Use the Vehicle Specifications API when you need transmission data alongside broader vehicle specifications.
What vehicles are supported?
The API supports 17-character VINs and vehicles from 1981 to present, according to the product specifications provided for this page.
Can I use the Transmission API alongside other Vehicle Databases APIs?
Yes. The transmission endpoint can be used as part of a broader automotive data workflow alongside VIN decoding, vehicle specifications, engine data, maintenance information, and other APIs.
