Have you ever come across a mysterious transmission and wondered what exactly it is? Well, if you’re lucky enough to stumble upon a Borg-Warner T-10 transmission, we’ve got some tips to help you identify it amidst the crowd. This legendary transmission is known for its durability and high performance, making it a favorite among car enthusiasts. So, let’s dive right in and learn how to spot one of these bad boys!

1. Look for Easy Identifiers πŸ•΅οΈβ€β™€οΈ

The first step in identifying a Borg-Warner T-10 transmission is to examine the casing carefully. Look for casting identification, as most T-10 transmissions sport a “T10” designation and the code “13-04” imprinted on their casing. The code “13-04” is made up of two parts – “13,” indicating the year of manufacture (1963), and “04,” meaning April. Keep this in mind as it can be crucial in determining the age of the transmission.

2. Decode the Tag Number πŸ”’

Another handy trick in spotting a Borg-Warner T-10 is to check the tag number that accompanies it. This tag number often reveals valuable information about the car from which the transmission originated. For instance, a tag number like “3A3-H-1” tells us that the transmission originated from a 1963 Ford Galaxie. These tag numbers act as secret codes that unlock fascinating facts about the transmission’s history.

3. Let’s Talk Gear Ratio βš™οΈ

The gear ratio can be a game-changer when identifying a Borg-Warner T-10 transmission. Remember, different vehicles require different gear ratios for optimal performance. So, pay attention to the gear ratio stamped on the tranny! If you come across a gear ratio of 2.64:1, consider it a clue that the transmission belonged to a 1963-1965 Corvette. Knowing the gear ratio can help you piece together the puzzle of its origin.

4. Inspect the Input and Output Shafts πŸ“

To further confirm if you’re dealing with a T-10 transmission, examine the input and output shafts. A genuine T-10 will boast an input shaft with precisely 10 splines and a diameter of 1.125 inches. On the other hand, the output shaft will have 16 splines and measure 1.375 inches in diameter. Pay close attention to these dimensions as they will set your identification efforts on the right track.

5. Investigate Shifter Locations πŸ‘ˆπŸ‘‰

The shifter location is an essential clue when trying to identify a Borg-Warner T-10 transmission correctly. Keep in mind that shifter locations may vary depending on the purpose and design of the transmission. Some T-10 transmissions have their shifters located on the tailshaft, while others have them positioned on the side of the transmission itself. So, don’t overlook this vital factor during your investigation!

6. Beware of Sneaky Modifications βœ‚οΈ

While following our identification guide thus far, bear in mind that modifications can throw you off track. Occasionally, enthusiasts make changes that erase the original casting identification or tag number from a transmission’s surface. In such cases, you’ll need to rely on other observable features like gear ratios or input/output shaft sizes to crack the code hiding within these modified transmissions.
