Unfortunately my little Autel code reader and data monitor thing doesn't see or catch trans temps IIRC. I'd really like to go to a scanguage type of setup but what I really want is a nice OLED MFD with configurable multi-gauge....
Used to use the paid Torque Pro app, but like the OBDII Link better.I use Torque Pro with a $15 WiFi adapter. Torque Pro is only $5.
is it just me or is the factory cooler a bit underwhelming?No. Only the liquid cooled one plumbed into the driver side of the radiator. Air cooled AT cooler was never installed stock in any '10-'19 460 in the US. The 470s could be equipped with them if they had tow package IIRC.
2020 with off-road package is the first US 460 year/trim to offer an external AT air cooler.
Quick check: Look through grill and if blank under horns it doesn't have the air cooler.

Here is mine during install of OEM cooler and what it would look like on a fully loaded Canadian GX 460.

Another note... only 3 zone HVAC 460s have the AC condenser fan in first picture. Two zone do not.
It's not you. I went with the factory cooler and all factory parts because it was factory. I did notice on a long road trip that transmission temps seemed to drop by about 10 deg F on average. I can still get to 200 F and above in stop and go city traffic. If I had to do the job again I'd probably go with a larger aftermarket. I think I put maybe 20k miles since the cooler install. I did a transmission fluid single drain/fill a few months ago and the fluid still looked pretty good.is it just me or is the factory cooler a bit underwhelming?
I'd have guessed something about double that size.
At first I got excited, been trying to figure out when the wax poppet valve first opens and looking at the bottom graph thought there it is! Then realized you pin the T-Stat open LOL.You could always take the loop connected to radiator out if a larger cooler doesn’t take you down as much as you want.
This we a before and after temp graph of to/from my cabin before and after adding OEM cooler 5 years back. I keep thermostat pinned open.

Are these at the Torque Converter or Transmission pan?
Either way I would be pleased with those temps after the cooler install, very happy.
The thermostat on the side of the transmission will maintain around 195-200 degrees. It fully opens up around 220degrees. I verified this using OBD-Link software while towing: The converter temp would climb up to 220-225 and quickly drop to 195-200. This occurred every 5 minutes or so. Temperatures are with an OEM cooler installed.I was told the factory trans thermostat would be enough to prevent overcooling of the Hayden 678. Once I get back home and can get the phone I use to monitor temps I'll see if I need to. Hoping I won't.
Can you post some pics of how it is installed, horn relocation, etc? What are your temps running.FYI, this doesn’t say that it fits the 1UR. I wouldn’t take the nearly $500 risk to see if it does.
On another note, I have the mountain passes off-road bracket and the Hayden 678 and they work great.
That's exactly what I saw. 10-15deg drop when driving; I'm on 285's and a 2.5" lift as well.It's not you. I went with the factory cooler and all factory parts because it was factory.

Do you have your thermostat pinned on the passenger side of the transmission @ the puck?
I was thinking of getting the mountain passes bracket but came across this from Kaon:

Also, it is not $500 USD. It is AUD. Closer to around $280ish, depending on the currency conversion at the time of purchase.
Brrr, that's FREAK'N COLD!!It is up to -2° right now pretty sure the ATF needs a bit of a warm up before I head to Costco this morning to see if they have any A5 Wagyu Ribeye in stock.
That’s a significant improvement even with the “small” OEM cooler. That suggests that maybe it’s not too difficult to keep temps in check if almost any cooler is added.You could always take the loop connected to radiator out if a larger cooler doesn’t take you down as much as you want.
