Good to know. Thanks for the heads up.The same issue can happen with the wiring from the body to the tailgate.
In case you discover that some of your rear lighting does not work…
A couple of years ago, my completely trouble free LX had an intermittent problem… while driving forward from a stop, the transmission would intermittently not want to shift out of first gear… had to drive home from lunch about 5 miles in first gear only.
After much research and puzzling over the issue, and a whole lot of entire vehicle assessment, I discovered that one of the back up lights was not illuminating. No codes set.
So I opened up the wiring in the tailgate and discovered that 4 wires were seriously chafed, cracked open and intermittently shorting to each other.
I replaced the entire section of wire and the back up lights began working correctly. Consequently, the issue with not wanting to shift out of first gear went away and has never come back.
My assumption is that the chafed tailgate wires and backup light issue was intermittently causing the backup lights to come on while I was driving forward… And PERHAPS, the PCM or transmission control module saw power across the transmission reverse switch and got confused. Thus, not allowing the transmission to shift out of first gear.
Just a semi educated guess… but problem resolved by repairing the rear lighting wires.
