The mystical automatic transmission of doom and annoyance, Weirdness of toyota VOODOO MAGIC Options

[neKronos]

So it seems that I have some sort of magical transmission in the es300. Now what what puzzles me is the events that have transpired over the past year.
#1
Just about a lil more than a year ago the car had work done don't remember on what exactly. But sometime after the transmission would completely disengage and wouldn't turn the wheels at all unless you turned the car off and back on in neutral while driving. Obviously the highway was out of the question, so the car sat for sometime while waiting till the weather got warmer to swap the tranny. Except for the occasional wifi excursion from my neighbors (gotta love unsecured). Weathers warm start the car up to go off to the garage problem has vanished completely with no reasonable explanation.
#2
Now a few days ago it started to slip and not engage again but this time kinda like when a clutch plate is worn down and you high rev. I thought I was just losing traction since the roads were wet reasonable conclusion since I do have baldish tires. Now yesterday went out to see some friends, guess it wasn't the tires slipping. So I check my other gears all slip except for reverse it runs like perfect, so I also inspect my Dextron III ATF, yea burnt to the color of engine oil. So today I go swap the fluids, didn't fix it I got pissed off, so I scrapped my oil change plans drove home, took a turn a lil hard and sharp. Accelerated through it and like wtf? all my forward gears are back to normal. Yay Highway!

Everythings awesome right? Wrong. The mystical solution to #2 caused #3!
#3
Upon coming home to investigate the miraculous self repair of my tranny. It would seem it forgot to repair reverse as I have no reverse, and my neutral is like drive. But park works just dandy. But in all honesty who really needs reverse? Its all about that pull through in the parking lots.

Got Damn I wrote a lot anyway. I'm beginning to think the shift linkage is the culprit... But I wonder will it fix its self like the other two times? Who knows what kinda voodoo magic toyota has put on their parts.
