This is about what I would expect. I have talked to both the dealership and I have a case open with Toyota. The dealership has told me they will do nothing until Toyota directs them to and Toyota has said they will do nothing until there is a code pulled or it is reproducible by the techs.

Looking back I was in sport mode the first time and normal mode for the 2nd. The observed behavior was the same - transmission temps around 200-215 when starting on the winding paved road getting into the 230-235F range at the end of the paved and gravel road and then increasing from there on...
I hope so too. Unfortunately driving in 4LO on a paved road is just not going to happen and is arguably unsafe given the gear/speed limitation. Even the gravel road would not be possible either, I would be backing up traffic forcing all the minivans and other vehicles to pass me in potentially...
All reasonable ideas however I keep coming back to the fact the transmission begins to heat up, getting to 3/4 if the way to red ~230F on a winding paved road that heads into a state park road that itself turns to gravel. I do not believe one should have to lower tire pressure, turn off traction...
This is fair and something I will absolutely try. I simply had not given it any thought to do this as I never had an issue with my past vehicle, it just worked however If this is what it takes for this vehicle to just work then it is something I can work with. I suspect an actual transmission...
You are likely not wrong but you can’t take the switchbacks much faster nor the turns on gravel roads in this state park either. When I get a chance I will fire up the ole 470 and see what temps it records on that same drive.
If others are able to share what temps they are seeing for normal...
I am not opposed to using 4LO, it simply means the vehicle is not up to task in my personal opinion and ultimately will lead me to sell the vehicle as a result. I can't put the vehicle in 4LO on a paved or gravel mountain road and hold up traffic or drive 15 mph on a 45mph paved road simply to...
Good idea, Tripod1404. I have not tried either of those things which I will add to the list the next time I am able to test. I have not found a set of inputs that allow me to get torque converter status unfortunately but will keep an eye out for it.
Thanks for the data point, berry802. I would be interested in what you see on a trail that does not require 4LO as this would be a more direct comparison. I could put my truck in 4LO on this particular trail and I suspect the temps would drop although it should be unnecessary and a more...

Feel free to DM me and I can share the route, it includes driving through Golden Gate Canyon State Park
69F on cold start this morning after sitting overnight.
This person is observing something similar in terms of elevated transmission temps albeit not actually overheating.
And here seems to be another report of high transmission temps. Perhaps something is wrong with my transmission specifically but perhaps I am not unique with regards to this...
I have not done anything with regards to transmission fluid. I am curious what a drain/flush would reveal however and I have discussed with the service center doing exactly what you have said, flushing the transmission but nothing done yet. I will have to pay to have anything done since Toyota...
Bottom left is engine oil temp
Bottom right is transmission temp #1
Top right is water temp
The vehicles transmission temp gauge was just outside of the red at this point. I have been able to overheat the transmission 4-5 times now pretty consistently.
I wanted to share my experience with the community in case others are having similar issues.
My Land Cruiser (1100 miles) is reporting overheated transmission fluid under certain conditions that my service center has been unable to replicate and therefore do anything about especially with the...
