A few pics of my alky meth install and trans cooler.

Yes sir. Experiment a little to see what works best for you. I did the same.

I needed to correct my temps from yesterday because figured they were too low... I double checked my pids on torque pro and must have entered something incorrectly. Using the Torque supplied Ford Trans Temp pid I ran the same test. The difference is its quite a bit cooler today.... a chilly 73° and raining. My temp after two brisk pulls raised to 140° in about 5 minutes drive time (basically around the block / 3 miles). As you would expect it will take longer to get up to operating temp without the tstat. But It beats the 286+° spikes I had with my 2013 MKS on WOT highway runs. Also it doesn't help that mercon LV is known for breaking down pretty quickly. Personally I'm comfortable with the 160-180 range on our setups. Especially being the lead foot that I am. Also note that it should also help with our condenser temps a little.

Keep in mind my cooler also has about 2 times the area as the PP version.

286 spikes!!!!! Holy crap! I can see where you are a lot happier with the 160 to 180 range.  Wow.  I will try and get that cooler (it was delivered today) installed this weekend and see where the temps hang out in the 110 degree heat here.

My 2018 post that started it all... Initially I thought it was a tune issue. It ended up being my trans running way too hot. This was on my 13 MKS. It addition it also did relieve the harsh shifting/bucking issues... So this is the setup I've been running ever since. My theory is that most people having harsh shift issues thinking it was the tune were also just having high temp /pressure issues. Just my theory.

Hopefully you replaced the fluid after those spikes, would suck to have done all that work putting a cooler in just to be running cooked fluid.

Yes sir. Surprisingly the fluid wasn't as bad as I expected but it was fresh fluid already. When I added the cooler I changed the fluid again.

Would have been  interesting to  get a Blackstone  report on the old fluid just to see what they find.

Yea. That would have been interesting to say the least.

Also torque gauges from todays drive... Was picking on a new Type R civic when i took this screenshot... Almost felt bad for him.

How did the t-stat cooler experiment ever work out for you? What route did you take?

So the cooler that I bought was much smaller than advertised. However I still removed the stock PP cooler and added the Derale. I have had two trips through the desert and the new cooler has dropped my fluid temps 20 degrees. I was seeing 217 to 220 degree at sustained 85 mph plus in 100 to 105 degree ambient range. With the new cooler it holds right at 200 with ambient temps in the 115 range. I left the trans t-stat in. New cooler works alot better.
