INFORMATION
Transmission Repair
Service Information bulletin B24 23 07 (Automatic Transmission Diagnosis and Troubleshooting) has been posted on BMW TIS. It contains
2010 BMW 750i xDrive AWD (F01) V8-4.4L Turbo (N63) Page 293
important hints and procedures needed to properly diagnose automatic transmission concerns.
It is required that all diagnostic and troubleshooting steps listed in Service Information bulletin B24 23 07 be performed when investigating all
automatic transmission complaints prior to submitting a PuMA case ("TC Case" or regular technical support "Case").
A PuMA case may be submitted ONLY after all appropriate diagnostic steps and/or hints listed in SI B24 23 07 have been 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 must include all the necessary information required by SI B24 23 07.
IMPORTANT
Both "TC Cases" and "regular automatic transmission technical support cases" will NOT be processed and will be rejected as "unjustified" if the
basic diagnostic troubleshooting procedures and corresponding information required by SI B24 23 07 are not performed and submitted.
Transmission Replacement
When creating a PuMA case regarding any automatic transmission complaint, please ensure that it contains ALL of the information required by SI
2010 BMW 750i xDrive AWD (F01) V8-4.4L Turbo (N63) Page 294
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.
^ 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 GM; all 6-speed and 8-speed automatic transmissions manufactured by ZF; and
GM VB-TEHCM modules and ZF Mechatronic modules replaced without a prior Part Replacement Authorization in PuMA will result in the
warranty claim being rejected. When submitting a warranty claim, the PuMA TC case number must be specified in the comment section.
TeileClearing is required for part replacement to be paid by BMW NA via Warranties: Limited New Vehicle Warranty, Certified Pre-Owned
Protection Plan, Federal and California Emission Control Warranty, Original Owner Protection Program and Extended Vehicle Protection Programs.
It is not required to submit a TeileClearing case for an out-of-warranty situation, i.e., BMW Center Administered Customer Assistance Program/Self
Authorization (Goodwill). When technical assistance is required to ensure "Fix It Right The First Time", please submit a regular technical support
"Case" and do not submit a "TC Case".
A Part Replacement Authorization is not required for replacement procedures described in Service Information bulletins, Service Actions, and
Recalls. Please write in the comment section of the warranty claim: "Replaced per SIB24xxxx" (substitute xxxx with the SIB number).
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.
