SUBJECT: New Transmission Designations
MODELS: E31, E34, E36
Situation: The former method of designating BMW transmissions does not provide the detailed description desired for identification of the new generation of transmissions. For documentation in Service literature an alpha-numerical designation system has been developed. These new designations clearly identify the major features of a BMW transmission.
Use of these new designations is being adopted by both the Service Training and Parts Departments.
Information: Designation

Two or three digit combination code letters may be added for special identification. This practice should be familiar to you from the Parts microfiches.
