This TSB has great pics of the cooler return filter part of the trans.

As it is, we still have a TSB (thank you dbleonard) for similar issues of fluid quality degradation due to heat:

That’s about all that can be done motosonic. I’m no expert but I’ve always left the paddle shifters alone too. That and besides corners I tend to drive it pretty easy.

Change fluid early and often per the TSB, or, add a larger external trans cooler not integrated with the engine's cooling core. No different really than any other vehicle experiencing trans, engine or power steering heat fluid issues.
Adding a cooler seems like a pretty expensive option. lol I'm guessing there's not one specifically made for the car, so I'll have to pay my mechanic to try and retrofit a generic one on the car somewhere.. I'll just get the fluid changed asap and hope it's not too late. I have like 53k miles on it now, and it's driven rather gingerly, so hopefully It'll be ok.
No, nothing specific for the Kiz (like everything else). A Hayden universal is what I'd go with if I were to put one in. That and some properly sized & rated fluid hose.
It's a pretty simple, inexpensive DIY...mounted in between the grill and the A/C condenser/radiator. The tricky part would be routing the hoses from the cooler filter cover and the Hayden. Possibly some home-fab'd mtg. bracket(s). The universal kits rely on a method of attaching it to the existing condenser/radiator through the cores. Not a fan of that idea. Hence universal. I added a small trans cooler the Toyota power steering system's fluid cool in my Samurai trail rig. Super-low-speed crawling in rocks w/ loads of steering input, pushing over-sized tires around, on hot summer days, was causing the old salvage yard pump to screech, whine and strain. Much like the issue w/ the K's CVT. Hot weather, hills, hard driving...cooking fluid, causing whine. I have to find a picture of that install to add.

I'd say you're probably fine. No additional coolers are likely to do much (without more planning than people care to give, as too cool is also not good), the Kizashi already has a loop through a CVT specific cooler + a loop through the radiator. Honestly, a drain and fill with a fresh CVT fluid every 30-50K is probably plenty of care for most use cases. Changing the CVT cooler filter around 50k (which would have 50k of the break-in wear, etc) would not be a bad plan. The 2010 and 2011 Kizashi have a TSB relating to the CVT pan, pickup, and dipstick for thermal issues (they enlarged them a bit for cases when there could be fluid starvation and overheating). Some 2010s and 2012s had CVT re-programs to fix CVT controller issues, and some 2013's had a CVT controller recall to replace a bad TCM.

If you really wanted to do this (Note: I think this is pointless for all but the hardest CVT abusers / insane people who want to race with a CVT) I would suggest that the thing to do is to remove the standalone secondary CVT cooler (about 24"x3" in the lower bumper opening) and replace it with a larger cooler. If the existing hoses fit you don't even need to change anything (excepting whatever is necessary to get a larger cooler to fit)
