Just like engines, transmissions have identifying codes that determine which replacement will actually fit. Finding yours is the key to ordering the correct unit the first time.
What Is a Transmission Code and Why Does It Matter?
A transmission code identifies the specific gearbox design and variant. Vehicles of the same make, model and year can use different transmissions, so the code — not just the model — is what confirms the right match.
Where to Find Your Transmission Code
On the Transmission Itself
Look for a tag, stamping or label on the transmission housing, often near the mounting points or on a metal plate.
In Vehicle Documents
Some registration and service records list the transmission type.
Via the VIN
Your VIN can help confirm the original transmission specification.
How to Use It When Ordering
- Record the code exactly as shown.
- Note whether it’s automatic or manual and the drivetrain (2WD/4WD/AWD).
- Provide your VIN alongside the code.
Frequently Asked Questions
What if I can’t find the code?
Send your VIN and a photo of the transmission tag — a supplier can often identify it.
Is automatic/manual part of the code?
The code identifies the specific unit; always confirm transmission type and drivetrain too.
Why not just use make and model?
Because one model can use several transmissions. The code removes doubt.
Conclusion
Identifying your transmission code is the surest way to order the right gearbox. Check the housing tag, your documents and your VIN, and photograph the code if you’re unsure.
