Transmission Class Action??

Pretty sure that Canada comment was tounge-in-cheek. .
It was indeed. I assumed we all were aware Land Cruiser is only made in Japan. One of the many reasons why they are what they are.
 
Has anyone actually run into this on the LC? It’s not exactly a subtle issue
 
Same 8-speed.

This is also a pretty active board, and so far no first-hand accounts of actual failures. You’d think if there was a systemic design or production failure with the 8-speed you’d see at least one account here.

There was a post I think at Tacoma forum years ago about the internal QC record of Toyota factories. It was Japan>Mexico>USA. So I am glad they kept production in Japan.

I would also put Stuttgart up there as well for superb QC and extremely high tech manufacturing plants.
 
Purely anecdotal, n=1. I've not had any serious failure issues like those described above but anytime I have felt any bucking from this drive train it has been coasting to a stop in traffic and I've attributed it to the safety systems fighting me, trying to downshift, brake harder and/or sooner than I would on my own (which itself is not aggressive by any means). I've never experienced any issues accelerating, on the highway or cruising quiet neighborhood streets, just in stop and go traffic. I've not yet taken the time to go through the HAL 9000 and disarm the all controls to verify this is the issue because the only time I think about it is when I'm either at my computer looking for reasons to freak out about how much money I dropped on this vehicle or I'm driving and it's not serious enough to make me pull over and give my undivided attention.
 
One problem with the LCs are the transmission high temperature/overheat that some people noticed (me included)
Typically over long steep climbs slow speeds in 4HI (there's a couple threads around)
Other than that is great. Leaps and bounds better than the slow 4Runner transmission.

Curious what temps you're getting? Here's a guide I found online, and would agree ~240degF is where I would start to get nervous.

Thanks for sharing. I will attempt to replicate that next time I'm headed to Panoche Hills, which has the same terrain and grade you describe in that original post.

I got 3/4 of the way up on the transmission temperature dash gauge going up a long and steep forest road. No alarms or anything. Just a bit of smell.
Please report your findings here and/or on the other thread.
 
I’ve gotten the transmission overheat warning twice. Both times at very low speed in steel grades for a prolonged duration. I just preemptively throw it into 4lo now if I see sustained steep grades. No more overheating

in 4LO did you see the temps within the middle mark on the dash or still went up (without overheat)?
 
If your driving off road with the transmission in D selection the tranny will probably get warmer than it should. The only time I saw the tranny get warm in my LX470 (off road toy) is on a gravel road with selector in D. I put the selector in 2nd and the heat dissipated quickly. The Lx470 has a large air to liquid tranny cooler. When I’m off road I never leave the gear selector in D. A good rule of thumb is if your off road and tranny is getting warm lower the maximum gear allowed.
 
I've been up and down several steep hills in the PA Wilds region on 3-4 hour gravel road/trail outings, regularly drive I-80 around Clearfield where it hits the highest point, all in 4HI, no issues. The climb around Clearfield is many miles long, is pretty much a long steady climb, and I've done it at 75mph with zero issues. No transmission overheating, warnings. etc.

The problem is the low speed, like 25-30 MPH or even less.
Offroad, forest roads, and not highways.
At 75MPH should be plenty of airflow and RPM to keep temperatures controlled.
