U1000 is class 2 comm problem. Likely loose, corroded, broken ground drivers side above frame near firewall.I got the new encoder both hooked up to the TC and hooked up electrically.
New TCCM is installed as i tested wiring integrity to verify it was good.
Now, the issue is that the new TCCM is throwing code U1000. It takes a good 5 minutes from the time i turn the key to RUN for all of the lights to go out on the 4WD switch. Getting farther, but still, stuck.
It shifts beautifully between whatever gear I select after it eventually works. No issues.
