Transmission Overheating - anyone else?

Actually quite surprised that a code is not stored after it shows a message that says to pull over. Even if the message disappears you would expect it to store that it happened. I mean my GR86 will record if I drive too fast or rev too high according to internet reports of denied warranty claims for those reasons.

It means it not a code, which probably happens at a higher temp
 
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 absence of any thrown codes.

On relatively slow (10-45 mph) winding paved and gravel roads that head up into the mountain near me, the transmission temp gauge gradually climbs to about 3/4 of the way to the red. If I continue on a dirt road that also puts the vehicle under load at slow speeds going up a hill the gauge will eventually hit the red and I will get a message that the transmission fluid temp is high and to pull over safely. This dirt road seems to be the trigger that actually overheats the transmission. The section of off-road trail is not tough trail and does not require low-range or even locking the center diff. Kias/Subarus have been on this part of road in the past.

I currently only able to read transmission temp sensor #1 from the ECU and between 245F and 250F the vehicle is overheated. At around 235 the gauge is 3/4 of the way towards the red. At one point I watched the temp gauge, in the span of about 4-5 seconds, go from blinking red (overheated) then drop to the middle point and then move back up to just below the red all while not moving.

As another data point, I am routinely in the 200F-215F while putzing around town which seems to be on the warm side however I do not really know what the expected normal operating temp is. I have also noticed that from about 130F to 215F the transmission temp gauge remains in the middle.

I am not able to replicate this issue while driving in the city or highway driving in the mountains.

Is anyone else experiencing anything similar? I would be curious to know what temps others have been observing around town and under load like mountain or light off-road driving.
Iam new to this forum as im trying to see if orhers habe had issues with 2024 LC.
Mine has transmission failure at 1004 miles. Started with oil marks on drive way which we never suspected it was LC but then got a hybrid malfunction code vehicle stopped in the middle of a intersection, endangered me and my kids . Took to dealer and they noticed moisture on gasket and thought it was a faulty gasket. When they replaced it found metal shaving and metal debris in transmission. Now no eta on transmission. Toyota is cold and unsympathetic. Idk if i should seek legal help.

Welcome to the forum Erika B. I am sorry that you are having such problems.

Yes sorry to hear you are having issues! Legal help? It is brand new and should be under warranty so Toyota should handle 100%. I would think you would also be given a rental until your LC is back in good shape. Was this not the case? Did the dealer not offer you this?

Contact Toyota directly. Not the dealer the Manufacturer. I would seek legal action if they are not fixing it but you have a Warrenty this most definitely will be covered!

Depending on your state of residence if repairs take longer than 30 days, or the vehicle is in the shop multiple times for the same problem in the span of a certain set amount of time; you might have a Lemon Law case to force a buyback.

Exactly. Personally I would go back to my dealer first but regardless of how effectively they were handling the issue, I would still contact Toyota Corp directly to make sure communication is going on between them and your issue is properly documented.

I was told by my Toyota that if a code is ever thrown, but the lights go off on whatever is wrong it’s because the car corrected itself. I was told that it is extremely smart and when itself corrects and the codes go away, they literally can’t pull them up again. I guess that means you have a light come on you should just go straight to dealership I don’t know.

Dealer is doing their best but as of now transmission is not assembled and they are thinking perhaps end of October on a new transmission.
Toyota casemanager completely unsympathetic.

Loner? Lemon law?

Pretty much, bc no assembly on transmission yet. Toyota parts think perhaps late October, so thats over 30 days. I dont want it back. Lets see what happens.

I hope everything works out to your liking..
 
The 2024 Tacoma's are having transmission problems . On today Apple News.
 
I wanted to provide an update for folks following my thread.

tl;dr - I sold the vehicle

My Toyota case was handed off to 3 different folks over the past 2 months since it was opened. They supposedly kept trying to contact Mountain States Toyota management and the service center to discuss next steps but apparently could not get anyone to return their calls. During this time, I took the vehicle on its first camping trip which convinced me that the vehicle was simply not up to what I expected.

Admittedly the vehicle did not overheat this time, it did get up to 225F on I70 heading up into the mountains. When I hit traffic and was stopped, I could smell the usual burning smell when the transmission was running hot. While off-road both oil and transmission temps got up to 235F and the transmission gauge was almost into the red but never technically overheated..

Something new and unrelated to my overheating transmission was the unpredictable nature of the power delivery in off-road situations. I spent 2 days off-road and had a full battery the entire time. going over obstacles or moving again on an incline from a stop either relied on just the 4 cylinder or I had to give it more gas than I would normally expect to get the turbo to spool. I found myself relying on momentum more than I had ever needed in my previous 4x4s. I find the 4 cylinder without boost or the small electric motor assisting is too anemic in off-road situations. Perhaps this is somehow related to my transmission issues or maybe a problem with my expectations but in an off-road scenario I fond the vehicle not up to task.

After returning from the trip, I received a call from Toyota informing me they had contacted another dealer/service center and could bring it it. I was additionally told that I would have to pay for the troubleshooting since there are no codes and no one could reproduce putzing around town.

This overall lack of interest by Toyota in finding out what could be going on, the service center not caring , and the prospect of paying to find out why my vehicle with 2,000 miles on it was overheating along with my experience on its first off-road trip was enough for me to get rid of the vehicle and move on. It's unfortunate as there were many things I liked about the vehicle but I could not trust it.

If there is a true problem you need to let it break with what it is supposed to do in order for the issue be legitimate; no codes when they look at it or test it isn’t enough and you have a warranty. Use it

I understand this position. I, however, was unwilling to beat on it to have it break on me, potentially out in the middle of nowhere just to get Toyota to do something. There was clearly a problem, that they didn’t want to look further into, fine.

Therefore, I chose to take the small haircut and move on.

Someone else can take over, let it break on them, and use that warranty.
 
Understand your position; it doesn’t help the product or the manufacturer though not produce the failure or it just could be an outlier. I have an LC250 1958 and nearly at 5k having taken on trips and Offroad conditions not seen anything like overheating. Hope you find what you enjoy and is reliable.
