Transmission Identification Code Basics

Transmission identification codes are unique alphanumeric sequences assigned to each transmission type in Volkswagen (VW) vehicles. These codes play a crucial role in identifying the specific transmission installed in a particular VW vehicle, providing valuable information for maintenance, repairs, and part replacements.

The transmission identification code is typically located on a metal tag attached to the transmission housing. It can also be found in the vehicle’s owner’s manual or service records.

Types of Transmission Identification Codes

Vw transmission identification codes

VW uses various transmission identification codes to distinguish different transmission types. These codes vary in format depending on the model and year of the vehicle.

Code Variations

Early VW models used a simple letter or number code to identify the transmission, such as “A” for a 3-speed manual transmission or “091” for a 4-speed automatic transmission. As VW introduced more complex transmissions, the codes became longer and more detailed.In

recent years, VW has adopted a standardized coding system that uses a combination of letters and numbers to identify the transmission type, gear ratios, and other characteristics. For example, the code “02Q” might indicate a 6-speed manual transmission with specific gear ratios.

Decoding Transmission Identification Codes

Decoding Volkswagen transmission identification codes is a straightforward process that can provide valuable information about the transmission’s specifications and characteristics. Here’s a step-by-step guide on how to do it:

The transmission identification code is typically found on a metal tag attached to the transmission housing. It consists of a series of characters and digits that represent the transmission’s model, type, and other details.

Character 1: Transmission Type

  • A:Automatic transmission
  • M:Manual transmission
  • V:CVT transmission

Character 2: Transmission Model

This character indicates the specific model of the transmission. It can be a letter, number, or a combination of both.

Characters 3-4: Gear Ratio

These characters represent the transmission’s gear ratio. The first digit indicates the number of forward gears, while the second digit indicates the number of reverse gears.

Character 5: Transmission Case Type

  • A:Aluminum case
  • C:Cast iron case
  • P:Plastic case

Character 6: Transmission Control Type

  • H:Hydraulic control
  • E:Electronic control
  • M:Manual control

Character 7: Transmission Input Shaft Type

  • F:Flange-mounted input shaft
  • S:Spline-mounted input shaft
  • T:Tapered input shaft

Character 8: Transmission Output Shaft Type

  • F:Flange-mounted output shaft
  • S:Spline-mounted output shaft
  • T:Tapered output shaft

Example, Vw transmission identification codes

Let’s decode the following transmission identification code: 09G 5HP19FLA

  • 0:Automatic transmission
  • 9:Transmission model
  • G:Gear ratio (5 forward gears, 1 reverse gear)
  • 5:Aluminum case
  • H:Hydraulic control
  • P:Flange-mounted input shaft
  • 1:Spline-mounted output shaft
  • 9:Tapered output shaft

This code indicates that the transmission is an automatic transmission, model 09G, with a gear ratio of 5 forward gears and 1 reverse gear, an aluminum case, hydraulic control, a flange-mounted input shaft, and a spline-mounted output shaft.

Identifying Transmission Type

Vw transmission identification codes

Transmission identification codes provide valuable information about the specific type of transmission installed in a VW vehicle. These codes are essential for proper maintenance, repairs, and replacement.

The first character of the transmission identification code typically indicates the type of transmission, as follows:

Manual Transmissions

  • 0: 4-speed manual transmission
  • 1: 5-speed manual transmission
  • 2: 6-speed manual transmission

Automatic Transmissions

  • 3: 4-speed automatic transmission
  • 4: 5-speed automatic transmission
  • 5: 6-speed automatic transmission
  • 6: 7-speed automatic transmission
  • 7: 8-speed automatic transmission

For example, a transmission identification code starting with “0” would indicate a 4-speed manual transmission, while a code starting with “6” would indicate a 7-speed automatic transmission.

Transmission Specifications

Transmission identification codes provide valuable insights into a transmission’s specifications. These codes contain information that can help determine the gear ratios, torque capacity, and transmission fluid requirements.

Gear Ratios

The gear ratios indicate the relationship between the input and output speeds of the transmission. These ratios are important for determining the torque and speed characteristics of the vehicle.

If you’re considering a new SUV, the 2024 Honda Pilot and 2024 Toyota Grand Highlander are two great options. Here’s a comparison of their features, performance, and reliability.

Torque Capacity

The torque capacity refers to the maximum amount of torque that the transmission can handle without sustaining damage. This information is crucial for ensuring that the transmission is compatible with the engine’s power output.

Transmission Fluid Requirements

The transmission identification code can also specify the type of transmission fluid required for the proper operation of the transmission. Different types of transmissions may require different fluid formulations to ensure optimal performance and longevity.

Troubleshooting Transmission Issues

Transmission identification codes play a crucial role in diagnosing and resolving transmission problems. These codes provide valuable information about the transmission type, specifications, and potential issues. By understanding the codes, technicians can quickly identify the source of the problem and determine the appropriate repair strategy.

Identifying Potential Issues

Transmission identification codes can indicate specific issues based on the combination of characters. For instance, a code may reveal a problem with a particular gear, a sensor malfunction, or a fluid leak. By cross-referencing the code with the manufacturer’s specifications, technicians can pinpoint the potential issue and prioritize repairs.

If you’re in the market for a midsize SUV, the 2024 Honda Pilot and the 2024 Toyota Grand Highlander are both excellent choices. Both vehicles offer spacious interiors, powerful engines, and advanced safety features. However, there are some key differences between the two models that you should consider before making a decision.

Guiding Repair Decisions

Once the potential issue is identified, the transmission identification code can guide repair decisions. The code provides information on the specific parts or components that may need to be replaced or repaired. This helps technicians make informed decisions about the most effective and cost-efficient repair options.

Compatibility and Interchangeability: Vw Transmission Identification Codes

Transmission identification codes play a crucial role in determining the compatibility and interchangeability of transmissions across different VW models. By deciphering the codes, you can ensure that the transmission you’re considering will fit properly and function as intended in your specific VW vehicle.


The transmission identification code indicates the specific transmission model that was originally installed in your VW. This information is essential when sourcing a replacement transmission, as it ensures that the new transmission will have the correct specifications and mounting points to fit your vehicle.


In some cases, transmissions from different VW models may be interchangeable. However, it’s important to carefully compare the transmission identification codes to ensure that the replacement transmission has the same gear ratios, torque capacity, and other key specifications as the original transmission.

For example, if you have a VW Golf with a 02E transmission identification code, you may be able to interchange it with a 02A transmission from a VW Jetta. However, you would need to verify that the gear ratios and other specifications are identical to ensure proper fitment and performance.


With a newfound understanding of VW transmission identification codes, you’ll be equipped to navigate the complexities of transmission specifications, deciphering gear ratios, torque capacity, and fluid requirements. Moreover, these codes become invaluable allies in troubleshooting transmission-related issues, guiding repair decisions and ensuring a smooth and seamless driving experience.
