I am getting a code P1635 when I scan car, I just changed the PCM and was told that not only does the key have to be reprogrammed but the transmission does to. Is this correct, I also have a problem shifting at around 60 mph, the car reaches 3000 rpm and higher

FLASH VEHICLE IDENTIFICATION BLOCK PROCEDURE
NOTE:If using a generic scan tool, follow scan tool manufacturer's instructions to perform this procedure.

To perform this procedure NGS scan tool, Ford Service Function (FSF) card and NGS Flash Cable (007-00531) must be used. Plug flash cable into scan tool. Plug other end of flash cable into Data Link Connector (DLC). From the scan tool main menu, select SERVICE BAY FUNCTIONS, POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
Scan tool display should show 2 selections. The first is selection is for old PCM information to be retrieved and stored. The second selection is for restoring new PCM with information that has been retrieved from the old PCM. Follow scan tool display instructions or refer to instruction sheet included with FSF card. If Flash Vehicle Identification (VID) Block has been reprogrammed previously, scan tool will display a message indicating the need to reflash entire Integrated Circuit (IC). This procedure can only be performed using Ford's Worldwide Diagnostic System (WDS).
