Transmission oil issue
96 tacoma 2.7 4wd 5spd 267k miles
About two years ago i changed the oil in my trans, tbox and diffs and today i went to change again to redline mt90 and when i drained the trans the oil looked like this(2nd picture). I had used valvoline full synthetic 75w 90. This is what my tbox oil looked like(1st picture)

Condensation build up from routine short commutes doesn't allow the oil to heat up enough and for long enough to evaporate the condensation and it eventually builds up especially during colder temps.

That's way more water than you'd get from condensation.
If condensation in gear oil was that big of a problem there would be more occurrences
Also, why aren't the diff's and transfer case bothered by condensation?
I'm guessing water got in there somehow. Are there openings that it could get in?
How about through the top through the gear shift?

I may be wrong but shouldnt there be another thicker rubber piece on the shifter seat?
All the grease was dried up and crusty so i cleaned it out and packed it new grease

As much dirt as you have on Top of the transmission I would guess no water getting in up there .
Now if it was clean aluminum with the dirt washed off.
I still say Condensation !!
I venture if I drained my Transmission Cold I would have just as much water.
Anyone ever have so much the transmission froze ??

Yes, like WY said originally, condensation. I have 6 motor boats I work on and none leak water in the bottom end but all the oil looks like this from condensation due to the fact the oil isn't getting hot enough to evaporate the condensation out. But perhaps you want wrench some more for fun

Do they hold a vacuum as well when empty?
An outboard lower end is sealed.
Where would the condensation come from?
Where would it evaporate to?

4runner A/T will shift smoothly into ALL gears but reverse. it will not shift into reverse at all. No grinding, or inclination at all that it is even trying to shift...solenoid maybe?

Due to the fact that gear boxes have vents meaning the Atmosphere can get in water to if you forget you have a wheeled vehicle not a boat
Last I thought about physics was some time back but both Hydrogen and Oxygen are present in the atmosphere .
Just like you get condensation in the roof of your sleeper when you turn the heat on it rains
One gets it in your fuel tanks as well

Old: Recipe on how to thaw a transmission housing in cold weather.1- Steel hog feed pan (the rubbers ones smell funny when you use them)
1/2-bag of charcoal briquettes (Full bag if your in a hurry)
1- Old heavy canvas tarp (New plastic ones melt too easy)
Squirt of charcoal lighter fluid (pint of gas if in a hurry. This requires a longer lighting device)
Lighter and or box of matches (propane torch if the wind is blowing)
Put the charcoal in the feed pan. Apply liquid lighting fluid of choice. Light charcoal/fluid. (IF gas was used, light and roll around until your sleeve burns out). Push pan under the tractor transmission. Cover top of the tractor with the tarp. Weight the edges to hold tarp down.
PS. Watch to make sure the oil drain plug is not over the feed pan. Had to repaint the tractor rear half when I did that, after I put the flames out. IF you are quick the paint will stick while the castings are still hot from the fire.
