I chose to add a trans cooler because in non track, spirited summer driving temps were reaching 240-250 and even the pre production units had issues of overheating with the cooler in track use. So at least with the trans cooler I won't have that constant headache if the temps might get too hot. Heck even the Lexus service manual states that for high temp, prolonged driving an external cooler is recommended.

I am used to seeing at least 20-30 degree drops from adding a basic cooler. 10 degrees is small enough that I would be curious to see the details of their testing. Maybe the 10 degree number is a mistake.

I'm not sure if its only 10 degrees, I mean I am taking readings before and after I install it next week but I think it will be more than 10 degrees. I had said previously that my temps w/o any cooler ranged from 240-250.

Alright finally got the OEM trans cooler installed, the install went super smooth all in all the trans cooler install took about 1-2 hours, hardest part being removing all the panels, bumper, and under tray. I took plenty of pictures with cool details so instead of making a messy and long post I condensed everything into a nice pdf for everyone to check out. As I point out in the pdf, the car was actually made from the factory to have a trans cooler, they just put a closed loop where the trans cooler lines would've gone. Only modification required was to drill and rivet the crash bar and drill holes into the plastic shroud. It took about a half quart of additional fluid. Being that the ports to add trans cooler lines are already there it would also be very easy for companies to make aftermarket solutions, I believe RR Racing might be pursuing that route with a future trans cooler kit for this car. I will report back after the new year with real temp readings, I took some before readings and once the weather clears up I will take some after readings in the same temps/driving conditions. Also forgot to add, I was going to paint the cooler all black, but I made a quick F logo stencil and painted it that instead, so it doesn't come like that from Lexus.

Yup their complete kit just went live and frankly I would’ve preferred to use the rr racing atf cooler just because it has double the cooling capacity. But at the time I got the oem cooler I had no clue if the lines tied in directly or if it required some special fittings. But after taking apart the car I saw that Lexus literally left a spot for an external cooler and just closed it off(pic in the pdf), so the rr racing cooler ties it straight to that.

Did you have any trouble with your front apron going back on. My concern if I do this install I will invite the front apron issue to cone right on in.

^^ I was thinking the same I am approaching almost 1-year since ownership & never experienced the Front-Apron issue (Knock on Wood). I am worried if I were to go the Trans-Cooler install route this will develop buy taking off & re-installing the front bumper. It's a gamble at this point.
