For those that have issues, has anyone done a survey between Hybrid and NON? Ive seen a lot of hybrids reporting this. Wondering is there any diff with the increased torque?

Took my 2025 4Runner TRD Offroad out yesterday to Slaughterhouse Gulch near Bailey CO, and after several steep hill climbs in 4Hi (drive mode) the transmission oil temp light went on and I lost power. I had to stop for 4 minutes to let it cool then switch to 4Lo. It was my mistake to do multiple hill climbs in 4Hi, I should have been in 4Lo. I've also heard manual (s-mode) reduces temp as well (compared to drive mode which shifts between 1st & 2nd often).

I have 2026 Land Cruiser and same issue has been reported by some owners.
Sounds like Toyota might rectify by reprogramming tranny to hold higher rpm before shifting (give up a bit of mpg, which they are certainly loathe to do).
my 2016 4Runner got on my nerves for low rpm shifting, but at least the 6 sp tranny was bulletproof by then.
For now, on road at least, the LC Owners Manual actually suggests using sport mode on long, windy mountainous roads. I think tow/haul mode might also work. Disappointing performance envelope omen for my new Land Cruiser tranny, but unfortunately part of new model/tranny shakeout. could also toss manual shifting into the options for long off road climbs.

Yea putting it in sport mode or tow mode on road on long windy mountain roads is what the dealer told me too which is ridiculous as sometimes the roads open up and I can actually gain speed and have to switch it around. I would have just bought a manual 4Runner if they still made them. As I've mentioned on here multiple times I can make the same drive in my Honda Accord without doing anything.I have 2026 Land Cruiser and same issue has been reported by some owners.
