Borg Warner is a well-known manufacturer of automotive components, including transmissions.
Their transmissions come in various models and variations, making it essential to have a way to identify and understand the specifics of each transmission.
This is where Borg Warner transmission identification numbers play a crucial role. In this article, we will explore the significance of these numbers and provide a step-by-step guide on identifying them.
I will also address some frequently asked questions to ensure you have a comprehensive understanding of this critical aspect. Let’s begin!
Why Do You Need Borg Warner Transmission Identification Numbers?
If you are new to vehicle customization, you might need to become more familiar with the term. What is Borg Warner transmission identification anyway, and why should you know about it?
In short, the Borg Warner identification number is a unique alphanumeric code assigned to each Borg Warner unit produced.
It serves as a means of identification and contains valuable information about the product’s specifications, details, and compatibility. For example, Borg Warner T10 identification codes will include “T-10”.
Knowing how to read these codes is essential for several reasons. Many street car owners would like to replace their vehicle’s automatic transmissions with Borg Warner T-5 transmissions.
This five-speed unit is a legend among auto enthusiasts thanks to its good gas mileage and excellent performance.
With this model, you never have to worry about problems like the transmission slipping after a fluid change.
Reading the identification number is a surefire way for novices who can’t identify an authentic T-5 transmission by its look.
Even if you are not particularly interested in the famous T-5, understanding Borg Warner identification numbers is still necessary.
Vehicles have specific requirements for internal components based on factors such as engine type, power output, and drivetrain configuration.
By decoding the identification number, you can determine if particular Borg Warner automatic transmissions are suitable for your vehicle.
This ensures a proper fit and optimal performance, helping you avoid potential issues arising from using an incompatible drive gear.
Finally, these identification numbers play a crucial role in maintenance and repair.
When it’s time to service or repair your transmission, the identification number lets you know you are procuring the correct parts.
Whether you need to replace a specific component or perform a complete overhaul, matching the identification number ensures that the parts are compatible and designed specifically for your transmission model.
How To Identify A Borg Warner Transmission: 4 Simple Steps
To identify Borg Warner automatic transmissions, find and decode the identification number.
In case the ID tag is missing, perform a visual inspection to check the number of bolts and the casting number imprinted on the transmission housing.
Read on and let me guide you step by step:
Step 1: Locate & Decode The Identification Number
As mentioned, reading the identification mark is the fastest option to recognize an authentic Borg Warner transmission.
Check the second tail housing bolt (right above the clutch), and you will see a metal tag. The identification number should be visible on it.
Once you have obtained the identification code, you can check the T5 identification chart for more information about the part.
Depending on the car model on which the transmission was originally installed, the appearance and material of these tags may vary.
For example, they are made of aluminum on most Ford models and steel on GMC models.
Since GM used steel to make the identification tags, they are prone to corrosion, and you might not be able to see the full number series.
In that case, go to step 2.
Step 2: Read The Stickers At The Forward Shaft Bearing
Here is a pro tip from seasoned mechanics: When the identification tag is missing or unreadable, you can still identify a Borg Warner transmission by examining the forward shaft support.
In every transmission this supplier produces, you will find a sticker that reads “Timken”, followed by a series of numbers, or a black-yellow sticker that reads “only use Dexron II”.
While these stickers are signs of an authentic Borg Warner transmission, they don’t reveal what model you have or what vehicle it is compatible with.
Step 3: Check The Bolts
Reading the Borg Warner T10 identification codes is not the only way to recognize a T-10. If you are looking for this model, another option is to count the bolts.
It is the only transmission that has 9 bolts on the side of its cover.
Checking the bolt axle can help you identify a Borg Warner T-5, too.
The regular T-5 on a Mustang has a six-sided bolt on the left side near the top, while the T-5 on a WC (World-Class) Mustang has a special security bolt with a star-shaped head in that spot.
Note that both types of bolts can be used interchangeably.
Step 4: Find The Casting Numbers
Finally, check the casting numbers, which are located on the transmission housing. When there is no ID tag, these numbers can reveal a lot about the model of your Borg Warner gear.
For instance, the casting numbers will begin with “1352” on a T-5, “1304” on a T-10, and “1309” on a T-19.
The table below lists all the casting numbers a T-5 transmission may have based on its original car model:
| Casting numbers | Car model |
| 1352065901 | NON-WC GM Chevette |
| 1352065902 | NON-WC GM |
| 1352065903 | NON-WC Ford |
| 1352065904 | Regular WC Ford |
| 1352065908 | 91-95 WC Ford |
| 1352065913 | WC Camaro/Firebird |
| 1352065914 | NON-WC Firebird |
| 1352065916 | NON-WC Firebird S-10 |
