I'm not getting rid of it. A transmission swap is no biggie. I just don't feel like messing with it, or paying someone else to do it.

Radiator is new, and I know it's not that.

Did you replace the trans after the milkshake? Do you have reverse when the trans is cold, or does it only disapear after everything is heated up or overheated in your situation?
Sitting for so long may have caused some dirt to get into the valve body or it could be an issue with contamination on the clutch packs.... Might be best to head to a Transmission shop and ask if a full trans flush has a chance of knocking things back into working order, but my guess is a full rebuild might be in order.

I've got an appointment on Friday to have it checked out before I start buying things.
It was driven a few times over the last 6 months, but not as much as I would have liked it to be driven. I had no issues putting it into reverse and backing out of my driveway on Monday. Once I drove 45 minutes to work I couldn't feel it go into neutral, or reverse. Once in reverse the RPM's would just rev up, and I just circled around the lot to a pull through spot.
I went out at lunch, and had reverse again. Drove home, and gone again. I shifted into neutral, and could still drive forward with resistance. I could put it into reverse, and go in reverse with resistance. The fluids look good, and don't smell burnt.
The transmission was not replaced after the milkshake. It's only a matter of time before it was going to need to be replaced. It has hard shifts through all gears. It also doesn't shift into 2nd until you reach 30 mph, and until everything has warmed up.

I've driven my brother's car that had a failing transmission, the first symptom is inability to shift. Soon after it stopped shifting gears while driving, it would "drift" between gears for a second or so before going to the next.
A happy 4Runner transmission will shift firmly and quickly, even after warming up.
Edit: missed that last post. I don't know how a thermostat would keep your transmission from shifting though, unless your coolant was transferring heat to the automatic transmission fluid in the radiator? It seems like an external cooler might be good prevention in your case, since over-heated transmission fluid will wear it out fast and cause strain on your transmission, which seems to have a history of issues.

When my tranny went out, the first symptom was failure to go into reverse when cold. It then progressed to failing to downshift into 1st gear without manually intervening at stop signs etc. I nursed it along for about 9 months before it give out completely.

That one is a first for me. Good to hear.

i think you have a trans issue too. the only possible thing i could see is your coolant got so hot that it heated the trans fluid to the point where it would not allow the truck to shift -at that point you should of had the AT temp light come on in the dash, and you would have almost guaranteed blown the radiator at that temp. im me we are talking like 300+*... i think you have a trans issue that is lurking in the shadows...

There's nothing lurking. There's been known issues for the last 12 months. It's just a matter of time, and it's not time right now. I just got back from driving it for about an hour, an have no issues. So the issue seems to be fixed for now.

Did you ever figure this out? Did you have to get a new transmission (OUCH!!)? If so...what did they say the cause of the failure was?
Thanks...

Nothing new really. Got it back on Monday, and did a short drive last night with no issues. I was told the thermostat was to cause of the issues. The AT fluid didn't have a burnt smell, and still looked new. Drove about 45 minutes on the highway today to work, and no issues. Shifts fine, has neutral, and reverse again. I talked with a Toyota tech this morning, and he said that the thermostat will affect how it shifts. We'll see what's next.

Toyota part?
Was it replaced with genuine Toyota part? The after market t-stats are to be avoided I'm told - and they look totally different.
