The Hayden 698 has a 180degree thermostat according to their tech department.

I'm on the fence between the 698 and 678.

I have the OEM cooler installed and the factory thermostat pinned. 90+ ambient temp I have a pan temp of 190-195deg; it always matches the coolant temp.

I am aiming to get it around 175-180 tops.
I use the 678 w/o a thermostat. In the winter I block my cooler 2/3 of the way with a sheet of rubber. Otherwise, it will get down to a max temp of only 120F or so, which just seems to cold. In the summer with the TCC locked it usually runs ambient temp plus 80-90 degrees or so, so 170F is a typical summer temperature for it.

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:

I have a 698 sitting in the garage to install. -3° tomorrow night and then single digits for high so not in any hurry to install it. But would like to install it before winter is over so that I can determine if I am going to need to block it in the winter. Only have ~5 months of winter left to do it LOL. Hoping that I don't have to block it but it is common up here, external cooler or not.
 
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.

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.

I have the Mountain Passes bracket sitting in the garage as well as the Hayden. I looked at the Kaon but in the end am more comfortable with the Hayden. And the price with the Mountain Passes bracket plus Hayden is a lot cheaper and don't feel the Kaon adds anything over that combo.

 
Kinda looks like what I was going for here. My version was about four bills cheaper. I don't think that the factory warmer/bypass even opens until around 190. @Acrad may be able to contribute but I think the system works fine in colder climates. I don't think blocking your cooler will have any effect unless you have pinned to bypass.

I have a 470 so it does not have the thermostat.

It's pretty easy to DIY a bracket out of steel or alluminum flat stock. $440 is a very high price for something so simple. The 678 is like $55 on Amazon.

Exactly. My 678 required one aluminum bracket that I made with some scrap so $50 in parts plus the fluid. $400 is crazy for what looks like the same cooler.

Anyone with a bench vise, hammer, drill, angle grinder, and crescent wrench can make a bracket :). I welded one up for my 470 but could have easily done so with bolts instead of welding.

Maybe I'll start making brackets for 470s/460s and selling them on the side as a kit for cheaper than others! I've been looking for an excuse to start a LLC.

EDIT: This is for my 470 - not a 460 - but is how I plumbed a Magnefine filter into my rig. I had it ran with just 3/8 trans cooler line but didn't like that the line felt a bit "pinched". This uses 304 SS 90 degree hose barbs that I bought online. A better way to do this would be to have 2 pieces of custom-bent hard line and 4 short hose connectors to the cooler and the lines that go back towards the transmission. But, this works pretty good, and I think it should flow-freely inside the SS fittings. I'm hoping to keep my trans fluid cleaner and push changes out to 50K or so.

I love the bracket idea. I have already put together a little kit for myself with the mountain passes bracket and installed it on my 460 and was thinking about a more oem approach for the wife’s.

With being a teacher and the kids getting older, I’ve thought about putting kits together for the 470/460 in my free time. If you actually make a bracket I’d love to see it, the mountain passes at $150 still seems expensive for what it is.

I have about 4 different LLC ideas right now and have not pulled the trigger on any of them :). It'd be worth it just for a tax break, honestly. I know quite a few people who have them and they are all very successful for lowering your tax burden.

I too have have an LLC (Monetti - https://www.monettillc.com/ ) with the main product being a tactical flashlight I've invented (I have a patent pending on it) but can't get the couple hundred thousand dollars for all the tooling to kick it off! I've created a working prototype that works awesome.
Anybody have a few hundred thousand dollars ($$$,$$$'s) laying around and need something to spend it on??? PM me!! :D

Probably easier for you as a device designer :). A bit harder for me as someone who works on "big" things and doesn't necessarily have 3D design experience for smaller items.

I've basically tabled any thoughts of adding a trans cooler since I installed the CSF radiator. It's over 50% thicker than OEM. I think that has to help trans temps somewhat.

Since my coolant temps never budge over 180 now, I'd think trans temps are likely to run about 200-210. I don't have a trans temp gauge. Are you guys reading trans temp off OBD or have you added a separate gauge? I'm not aware of a factory temp sensor, but it stands to reason there might be since there's a thermostat....

I use a scangauge 3 (scanguage 2 can do the same) and monitor transmission pan temp (AT temp 1), and torque converter tempt (AT temp2). it's based off factory sensors.

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....
