The Volkswagen transmission code, often embedded within the Vehicle Identification Number (VIN), provides crucial information about your car’s gearbox. While the VIN itself doesn’t directly reveal the transmission code, understanding part numbers on the transaxle casing, like “113 301 103,” can offer valuable clues. Decoding these numbers helps identify the transmission type, original vehicle model, and even pinpoint potential manufacturing variations.
Deciphering VW Transmission Part Numbers
Volkswagen uses a specific format for transaxle part numbers. Let’s break down the example “113 301 103”:
-
The First Digit: The initial “1” indicates the transaxle case was initially designed for the Type 1 Volkswagen (commonly known as the Beetle). However, this doesn’t mean it was exclusively used in Beetles. Volkswagen often utilized parts across different models. A leading “2” or “3” would signify its origin in Type 2 (bus) or Type 3 models, respectively.
-
Model Number: The “13” represents the Volkswagen model number. In this case, it signifies association with the deluxe export model.
-
Parts Manual Section: The following “3” directs you to the “Transmission” section within the original Volkswagen parts manual for further details.
-
The Core Part Number: The remaining digits, “301 103,” constitute the specific part number for this particular transaxle component.
-
Mold Numbers: Numbers like “44” often represent mold numbers used in the casting process. This allowed Volkswagen to track specific molds and quickly identify any flaws detected in production.
Resources for VW Transmission Identification
Locating original Volkswagen parts manuals can significantly aid in deciphering your car’s transmission. These manuals often include comprehensive diagrams and detailed part lists:
-
Online Resources: Websites like http://www.oacdp.org/ offer access to digitized versions of these invaluable manuals. Look for sections like “Upcoming” or specific model categories (e.g., Type 1).
-
Progressive Refinements: “Progressive Refinements” documentation meticulously details changes and updates implemented by Volkswagen throughout production. This allows for remarkably precise dating of components, sometimes down to a specific week or even a few days of manufacture. Using these resources, alongside knowledge of your VW’s VIN, can help determine the original transmission specifications.
Using VW Parts Manuals for Identification
Navigating these resources provides crucial insights:
-
Exploded Diagrams: Visual representations of assembled components facilitate understanding relationships between parts and aid in accurate identification.
-
Part Numbers and Names: Combining part numbers with official names streamlines online searches for components. This ensures you find the correct replacement parts for your specific transmission.
By understanding the coding system and leveraging available resources, you can decode your Volkswagen’s transmission and gain valuable information about its history and specifications. This knowledge empowers you to make informed decisions regarding maintenance, repairs, and restoration.
