04 f150 issues

Need help. My 04 f150 just didn't want to move when in drive. Did code reader and ended up replacing sensor and throttle body but still nothing. Tried replacing the pcm but now it's stuck in anti-theft mode. Is there anyway to bypass it? Please help!

4.6 liter. And the codes got were 2106 and 720. Which was the throttle body and sensor. Replaced those came back with no codes. Put the original pcm back in it for it to start again and now I have no gears.

have you checked the drivers side of the tranny ? plastic shift linkage holds the cable and breaks.

Check Main wiring harness from PCM down pside of engine between the firewall that run to transmission they are bad to come loose from there hanger and when it does the harness touch's the passenger side rear exhaust manifold and melts wires to the manifold or other wires in harness seen this on a couple of 04-08 F-150's and a 2006 Navigator already
