Thanks to everyone in advance,
I have just swapped my transmission on my '07 Pontiac G6 GTP (3.6L, A6) to an '08 and I am having issues:
1. Speedo is not working.
2. Manual mode is not working (which I'm not really worried about).
Here are the OLD SETTINGS:
TCM OS: 24240291 C714
ECM OS: 12611134 172A
Here are the NEW SETTINGS:
TCM OS is: 24244551 E46C
ECM OS: (SAME)
When I first tried to write settings from the old setup, I got an error saying that the operating systems didn't match. I then hand copy-and-pasted all the settings from the old transmission into the new and re-flashed the vehicle. Speedo still does not work; it moves, but it will read about 18mph at 50mph. I have no MIL at this time.
Does anyone have any ideas?
