As the title would imply, I did a reset on my TCCM because I cant get my 04 envoy to come out of 2 wheel drive after having replaced the transmission. I did this by unhooking the battery, and unplugging the TCCM (hooking back up in reverse order) as a mechanic friend told me to do. However when I hit the key it was like there was no starter or anything there. No click, no dimming of the lights, no nothing. I have a few codes about data link malfunctions that keep coming back and I did check the neutral safety switch and ignition switch. I am stumped. Any ideas?

Check your TCCM connections, you may have some bent pins. Unplug TCCM and try to start as well.
