INFORMATION
Transmission Repair
[NEW]Diagnosing symptoms involving automatic transmissions and determining when a replacement is appropriate are areas where specialized assistance is often needed. Due to the high cost and complexity of the 5 and 6-speed automatic transmissions, an Enhanced Technical Support process has been
developed to help identify the root causes of customer complaints relating to automatic transmissions.
Service Information Bulletin B24 23 07 (Automatic Transmission Diagnosis and Troubleshooting) has been posted on BMW TIS. It contains important hints and procedures needed to properly diagnose automatic transmissions concerns.
[NEW] It is required that all diagnostic and troubleshooting steps listed in Service Bulletin B24 23 07 should be performed when investigating all automatic transmission complaints prior to submitting a PuMA case ("TC Case" or regular technical support "Case").
[NEW] A PuMA case may be submitted ONLY after all appropriate diagnostic steps and/or hints listed in SI B24 23 07 were completed and diagnostic results are inconclusive (regular technical support case), or when a component replacement (transmission, Mechatronic, or VB-TECHM) is requested ("TeileClearing Case"). Such a PuMA case has to include all the necessary information required by bulletin B24 23 07.
[NEW] IMPORTANT
Both "TC Cases" and "regular automatic transmission technical support cases" are NOT going to be processed, and will be rejected as "unjustified", if the basic diagnostic troubleshooting procedures and pertaining information required by SI B24 23 07 are not performed and submitted.
The repair procedures and recommendations that the transmission technical specialist provides to you through the PuMA case are stored in the PuMA system. When BMW NA pays all or a portion of an automatic transmission replacement or repair in all Warranty, Goodwill, or Certified Pre-Owned claims, the PuMA case will be reviewed by the Warranty Department to verify that the inquiry and repair instructions match the claim submitted.
[NEW]Transmission Replacement
When creating a PuMA case regarding any automatic transmission complaint, please ensure that it contains ALL of the information required by SI B24 23 07, including, but not limited to:
^ A full description of the complaint and whether or not the complaint has been verified.
^ A detailed description of the operating conditions, environment, road conditions, anything related to the complaint, or the conditions under which it can be duplicated. The details must be sufficient to ensure that the person reading your case will be able to understand the situation and/or duplicate it if necessary.
^ Identify any work performed during each service visit for the same complaint.
^ Results of tests performed, i.e., measurement of wiring harness resistance values, etc. Always provide specific readings and observations including Check Control messages, fault warning displays, range displays, modifications to the vehicle and verification of approved wheel and tire combinations. Statements such as "in spec" are not adequate.
^[NEW] Include "GM" or "ZF" in the subject line and the transmission serial and part numbers from the ID's tag in the "Work Performed" field of your case.
^ Include the transmission fluid level and condition.
^ If the problem concerns shift characteristics, include the specific shift (i.e., 1-2, 2-1or 3-2), vehicle speed, road condition (e.g., uphill), etc. in which the complaint can be duplicated.
^ Where fault codes are stored, include the name of the module concerned in "problem description" and the actual fault codes in the "fault code" box.
^ In order to aid the diagnosis, your diagnostic tester must have transmitted FASTA data indicating that all relevant test modules have been completed.
Always refer to SI B24 23 07 for diagnosis and troubleshooting hints regarding 5 and 6-speed automatic transmissions.
WARRANTY INFORMATION
All 5-speed and 6-speed automatic transmissions manufactured by ZF and GM, as well as GM VB-TEHCM modules and ZF Mechatronic modules, replaced without a prior Part Replacement Authorization in PuMA, will result in the Warranty, Goodwill or Certified Pre-Owned claim being rejected. When submitting a warranty claim, the PuMA TC case number must be specified in the comments section.
[NEW] A Part Replacement Authorization must be obtained even if a Service Information Bulletin states to replace any of the above-affected TeileClearing parts. Exceptions are Service Actions and Recalls.
[NEW] A Part Replacement Authorization is required even if the service is performed during official BMW NA non-working days, i.e., during weekends (Saturdays and Sundays) and any official BMW NA holidays.
