That is what OBDLink MX+ is, you add your own OLED Device as long as it is Bluetooth enabled. Most people use their regular phone I elected to buy an unlocked cheapie unlocked phone Black Friday a year for display using OBD Fusion. You can configure Fusion with whatever you want it to display. And can totally customize the displays. Over the last year I have played around with mine and have it to where it makes the most sense to me.
Or you can use radial gauges like @jeremy j posted just a bit ago with lows and highs, min and max, etc.

Used to use the paid Torque Pro app, but like the OBDII Link better.

On the 460 anyway I wouldn’t go back to Torque. OBD Link Fusion/Link was worth the cost. I consider it about as close to a portable Techstream without bidirectional control. I haven’t checked again in last few years but when I played with Torque years back it still couldn’t see all the 460 ECUs and seemed to require formulas for some basic monitoring.

I used the Torque app early on when I had my Hundy (pre GX) and a no-name BlueTooth OBDII dongle.
When I got the MXLink I thought I might as well just use their app too. But Acad is right, it is easier and can tap into more of the vehicles ECU's than Torque.

is it just me or is the factory cooler a bit underwhelming?
I'd have guessed something about double that size.
You also have different types of AT coolers to choose from

The Different Types of Transmission Coolers
Transmission coolers keep your transmission fluid cool. There are three main types: tube and fin, plate and fin, and stack and plate. Learn about them all here.
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.
If anyone is looking for a REALLY good trans cooler, I would direct you towards this company:
They are more expensive, but I will probably use them because it seems like the kind of thing where "cry once" makes sense.
IME, tube and fin is pretty fragile and needs some kind of protective screen or chicken wire or something over it.
I like that Setrab lists actual heat rejection figures and has a metric o-ring boss port as standard. This is much more robust and reliable than any barb fitting.

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 is a before/after temp graph of to/from my cabin before and after adding OEM cooler 5 years back. I keep thermostat pinned open.

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.

Are these at the Torque Converter or Transmission pan?
Either way I would be pleased with those temps after the cooler install, very happy.
Graphs are of Transmission pan sensor
I think the thermostat opens at 190F. I was in the Chic fil a line today, idling for 15 minutes. Trans temp and coolant temp were in equilibrium at 190F for 5-10 min, then suddenly drops to 188F pan temp. TC was 201.
I only saw the top portion of the picture and was like dang that's a flat line. Then I realized there was more. Drove 8 1/2 hours today so I should probably rest.
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.
Can you post some pics of how it is installed, horn relocation, etc? What are your temps running.
Also, it is not $500 USD. It is AUD. Closer to around $280ish, depending on the currency conversion at the time of purchase.
That's exactly what I saw. 10-15deg drop when driving; I'm on 285's and a 2.5" lift as well.
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:
Transmission Cooler Kit to suit Toyota Prado 150
Transmission Cooler Kit to suit Toyota Prado 150 1KD & 1GD - KAONwww.kaon.com.au
Cruiser Brothers sells the Australian made Wholesale Automatic Transmission cooler which is similar to the Kaon made for the Prado 150. They had to modify the mounting brackets on it to fit the Lexus GX, supposedly they fit now they did not before. I just dug up my email from them earlier in the year. Total was $477.50 with a 10% discount it was $95 shipping from Australia. Don't forget the shipping cost from Australia, it isn't cheap.
Hayden 698 internal bypass cooler is $60 but it is made in the US, not Australia LOL.
2019-21 Tundra has the A760F transmission and they dropped the cooler on those year models. Same issues on those rigs they run 230-250. A guy on the Tundra forums started building tranny cooler kits with the Setrab 15 row coolers for ~$1,200. They are extremely popular with the Tundra guys.
Pinning the transmission T-Stat bypass open would be something I'd do all year if I could but not a good idea here. 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. Would have to unpin the thermostat for at least 7-8 months of the year where I live. As a safe bet could use the same schedule that they add anti gelling blend to diesel fuel.

Brrr, that's FREAK'N COLD!!
Just made a stew with Costco Wagyu beef a couple weeks ago. Oh, man!!! That was goooood!
I'm surprised how reasonably priced it is.

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.
