1. the 722.9  valve body is not interchangeable with any other 722.9 transmissions. The hydraulic unit what includes the TCU module is married to the vehicle, it will not work correctly in another vehicle (only limp-home mode)
2. If you have customers with shift quality complains on the 7G-Tronic Transmission 722.901 and NO fault codes in the computer. Most likely, there is nothing wrong with the transmission it self, please flash the transmission with the latest software contained in the latest SDflash Release CD 0004488102/0008
3. If transmission control module is new or transmission is replaced, then part of the installation process would be to release transport protection
   and personalize (marry) the module
4.  Control module software can be loaded using SDS / DAS and the appropriate update CD ROM disc (flashing). This process does not erase the factory algorithms that were written to the control module during manufacture
5.  Flashing of the control module would be performed: - after replacing transmission - after replacing electro-hydraulic valve body - to update the control module software to resolve a problem
6. You remove the hydraulic control unit, or the hole transmission for repair, in the most cases depending on the scenario, the transmission will NOT run !  You have to teach in the "Range selector sensor "
7. If you have to flush the control module some or all of the following will need to be performed after flashing the transmission control module:
   Ø Determine vehicle data for SCN coding
   Ø Performing SCN coding
   - as of MY 2005 performing CVN process in addition to SCN
   Ø Learning the drive authorization system (required with new module)
   Ø Teach-in of selection range sensor
   Tip: Ensure SCN coding is available before programming control module!

           Attention:            

1.  As of MY 2004, transmission control module will incorporate SCN coding (Software calibration number) SCN code will need to be entered using SDS / DAS after every software update  Failure to enter the SCN code after software update may result in "engine not starting"
   Tip: Ensure SCN coding is available before programming control module!
2. The SCN code is comprised of a multiple digit/character coding string, an SCN and a check digit! It is created using the VIN based factory specification data for the vehicle in addition to the part number of the ECM replaced or flushed. It identifies both the control unit software as well as the coding confirming to the specific vehicle.

3. You working on this Transmission--NO POWER TOOLS-- • Transmission housing is die-cast magnesium
   • Requires aluminum bolts due to: - steel bolts having a different expansion rate - corrosion concerns with steel bolts
   • Aluminum bolts must be replaced if removed!
