I would not mess with transmission cooling if you are still under warranty. Doubt it would make much difference if you wait to do it after warranty expires.
For AT temps I like my OBDLink MX+, but there are cheaper alternatives out there.
That’s great info Acrad thanks. So from what I understand, the system is largely passive, but the valves to the accumulators are ECU controlled, and close under certain conditions such as at higher speeds (to stiffen the system and thus the sway bars).
so vehicle height should have little to do...
Make sure you test the lean on a number of very, very flat surfaces. Spin the truck around a few times too, to see if it changes anything. Small floor irregularities can drastically change how much lean there is.
My 2014 GX460 has a lean at 90k miles just like yours (rear passenger side is...
Thoughts about putting a person’s weight on the end of the rear door? Curious about integrity of the door hinges over time.
obviously the side ladder version shouldn’t have this issue
Just reporting back after driving through a couple of tanks of gas (this boi is thirsty!)
KCLV values (fluctuates a little:
87 octane: 16-18
91 octane: ~23-24
Yummy 93 octane: ~26
I might be able to convince myself that premium gave me 1 more mpg (17 vs 16). But that’s probably within error...
So I’ve been eyeing closely the fuel trim numbers in my 90k mile 2014 GX460 on OBDLink. Truck drives with no issue and no codes are triggering for me.
At idle (550-700rpm):
LTFT Bank 1 +3.1%
LTFT Bank 2 +0.8%
At 1500-2500 rpm:
LTFT Bank 1 +2.3%
LTFT Bank 2 +3.1%
STFT appears to fluctuate...
Do you guys have any thoughts about using an aftermarket (say, 20,000 BTU) AT cooler that bypasses the internal radiator cooler? I wonder if that's enough to keep the AT cooler than stock. There's really very little info out there on BTU vs temps for a bypass setup.
I would imagine so, since...
Might be worth bringing to a shop to do a little baselining. Do you know if the brake system was ever serviced?
I had my brakes bled and front pads/rotors changed (they were warped) and brake feel is about 50% improved, and a little less squishy.
…and to the issue of power - check out post #72 at this link - example is from testing KCLV vs dyno results for the 2UR-GSE in the Lexus ISF.

If KCLV makes a difference in power, that would likely explain the improvement...
You know I’ve read many reports of that too - that so long as it doesn’t knock, there is no harm using 87 whatsoever.
We probably can’t assume the LS3 and the 1URFE behave similarly when using different octanes, however.
which raises 2 questions:
1. I assume by the way Toyota designed the...
That does make sense - since the ECU retards timings with higher engine load.
I will fill up on premium after the truck gets back from the shop and report back.
