Transmission Control Module Flash (EEPROM) Programming
The introduction of newer generation Transmission Control Modules introduced with the M44, M52 and M62 engines at the end of 1995, brought with it the ability to "flash" program this module as well. By being able to electrically erase and install a new program and or data stored on the EEPROM, it no longer becomes necessary to replace the chip to get an updated transmission program installed.
The technology used on the Transmission Control module is the same as explained in the section " ENGINE CONTROL MODULES FLASH (EEPROM) PROGRAMMING ".
