since the pin expands at 190*F, there would be no way to electronically change the setting at which the pin expands. Does anyone know if like a ball valve that opens and closes at certain temps that are for automotive use exist at all?

Define Hot lol. Both stop to work after 230 so not that hot.@flyhalf Do you think the cooler that you are running now could be swapped out for a smaller one to heat up the fluid a little bit more? I noticed that you mentioned that you would like to be at 160*F minimum and I agree with that. My ideal trans temps would be between 170*F-220*F absolute max. From the research that I have done, the 6r80 and 10r80 were designed to run hot and if they were designed that way, then the assumption is that they would be most efficient around 190*F
Well, I mean the oem fluid expands with heat and they have it setup for the thermostatic bypass to open at 190* which I would assume the fluid is a a certain viscosity and thinner (10r80 even thinner) than when cold for the seals and parts on the lead frame to work properly. From what I read, there is something like 150-250 psi inside the trans when shifting gears. excuse my lack of vocabulary as I'm not an expert obviously lol.Define Hot lol.

There is an easy solution.
External thermostat.
IMPROVED RACING has one.
Different options for opening 140 160 180
And still allow 10% flow even when close.
So you make a bypass on the trans and add this
Check that!

Because is 24 7 open the level is actually more "real " with the bypass cause is already circulating.@flyhalf I was also curious how you go about checking your trans fluid levels. as you already know the fluid level is checked when the thermostatic bypass opens up and all the fluid is cycling through the cooler and at 190*F. And since the fluid expands, its going to be at a higher level than when at 120*F.
So I took my new 10-speed Dark Horse to the track for the first time, didn't push it that hard and had transmission cooling issues. After 6 laps at Buttonwillow Raceway the transmission oil got to 280F when it was 65F outside.

@flyhalf think that would help?
No. At least not only. You already have a cooler that works well. I forgot to answer you.
