Be VERY GENTLE with this. The pins in there may be a little stuck and you don't want to break them off. Spray it all with DeOxit and let it dry before putting it together. And rub a little dilectric grease on the seal too. You don't want moisture getting in there -- that's where like 90% of transmission electrical problems come from.
yes, i have seen the handle, even wiggled it and tried to pull it upwards, it didnt budge. you mention a button-to push. where exactly is this button?

@AuSeeker , am intouch with the author of that video, he still is unable to explain insimple terms how to unclip the harness

Dropped the pan and drained and refilled. Then did another drain and refill 500 miles later. Car drives fairly ok now, even did a 300mile round trip recently, smooth shifting. Yet error code refused to go away, erased it several times, even unplugged the battery. Also removed the suspect solenoid from the tranny and tested it.tested ok with 12v and read 14.6ohm. So i wonder what the issue is, perhaps the cable tranny or ecm side.

Am still unable to unplug the cable harness, perhaps will try and buy the replacement cable harness to see if that will give me some insight in unplugging it. just not keen on spending money buying a part i may not need

So stumbled on this old thread and another more extensive youtube video which showed how to unclip the harness by pressing down the hook/tab like lever or access the port directly by cutting up the sheet metal.

I also ran across this video and subscribed to his channel at that time plus another video that also cut the sheet metal to get to the connector and replaced a pin or two, but it's been a few years ago and I couldn't find them when I posted my post you quoted, but this seems to be the best approach to fixing the issue without replacing the harnesses.

Looking for wiring details for the transmission soleniod harness connector. This is the connector on the outside of the transmission housing that is part of the main wiring harness. Need to reconnect the wires to the connector but have no idea which color wire goes to which pin on the connector. Found a vendor selling a pigtail replacement but still need to figure out the matching OEM wire colors since the replacement wires appear to be all blue.

Thank you!

so how where you able to resolve this.
i discovered a snapped cable on my harness as well. the pins are shiny and zero corrosion, so i think changing the harness is the easier option.

i intend to simply follow the route of the old harness, cut and splice the cables sequentially. not so sure why you think you need extr electrical disgrams for the splice and swap
