What would you want to do with your Seltos that requires a cooler?
From all the literature I've read, the duel clutches tend to be prone to overheating. Keeping the tranny even 7 degrees cooler can make a real difference in the prevention of overheating.
You’d have to do some heavy stop and go, offroad type driving for the tranny to overheat. I wouldn’t worry too much about it unless that’s the kind of driving you plan to do.
Quick lesson on transmissions! All clutches in any vehicle are used to connect the transmission speed to the engine by the use of clutch plates, thus they are all dry! The transmission contains the speed gears) however, requires a special fluid produced for the series transmission it goes in, thus called transmission fluid allowing the speed gears to shift from different speeds ie, 1st, 2nd, 3rd gears etc. In automatics however, the torque converter (it having fluid as well) is the connection between the transmission and engine. Your comment absolutely makes no sense once you understand the purpose of clutches and torque converters.
Wet clutches in general have multiple clutchplates (in cars) and have a supply of oil to lubricate and cool the components. ... Dry clutches on the other hand have no oil supply and are generally single-plate.
I am not stupid!
Clutches CONNECT the actual transmission gears to the engine. Thus clutches are dry, but the transmission has fluid! Clutches are only used to to do this function. This is why you dont want to hold your car on a hill with the clutch engaged, it gets hot and not the transmission as it, and not the transmission first gear gets the excess torque. And my request pertains to the speed side (with fluid) and NOT the dry clutch side.

You seem to be really confused. The Seltos has a dry clutch DCT. Manual transmissions are generally dry clutch. In both cases, oils will detrimentally affect how the clutch operates. My Audi has a wet clutch DCT. The K5 has a wet clutch DCT. Wet clutches are a real thing and are used in various devices such automatic transmission torque converter lock ups, motorcycles, dirt bikes, and industrial equipment. They are oil bathed clutches, hince the term wet clutch. Dry clutches are a real thing and are used for manual car transmissions among other things.

You're right and you're not stupid either. The person offering the correction is misinformed.
Here's the main issue. Your talking apples to oranges here! How you illiterates turned this conversation from the gearbox in the tranny (which has fluid), to the duel clutch that allows the change of the operating gears, I will never know!
So yes, you are stupid as it seems your not able to comprehend the original question.
Which is: Can a tranny cooler be connected to the the duel clutch transmission? Now very slowly reread the question and answer that, without bringing in the duel clutches, that are dry.
The problem is, I really don't know if it can be done. And I do get so amused when people answer the wrong question because they seem to have a hard time understanding what is asked, and not what think they are answering.

Actually, all I did is correct your general ignorance. Notice, I didn't call you a name. I stated that your were confused. Actually you don't seem to have a clue. Do you really want to enter into a debate with a Mechanical Engineer who has both automotive and defense experience who learned what a wet clutch was in design of machines class? You were the one who went off subject in your feable attempt to explain how wet and dry clutches work. Don't go all crazy when you lead the subject off topic. I was only explaining that you know not what you are talking about.
I'm not obligated to answer your questions because you don't sign my paycheck. I will humor your request in this case because it further illustrates your confusion. Try to be polite if you can manage.
What I find most entertaining is the suggestion that a traditional transmission cooler will do anything to keep the clutch pack cooler. You called me stupid but came up with that idea. Priceless. Transmission coolers are to cool fluid by means of a heat exchanger. What happens in a dry clutch transmission isn't overheating of the gear oil in the transmission but the overheating of the clutch pack itself. Thus, putting a traditional liquid heat exchanger serves no purpose. The gear oil is not likely to ever need cooling but too much slipping of the clutch is bound to overheat the clutch. One can reason a cooler would help in excess slipping with a wet clutch system because a fair amount of that heat from slipping would be dumped into the fluid and you can cool that with a traditional transmission cooler. This isn't an automatic transmission which would actually benefit from a trans cooler.
Please stop calling people stupid when you don't seem to know what you are talking about. I didn't take much offense because it was coming from you. A transmission cooler for a dry clutch DCT clearly wasn't your finest hour.
If you understand how a wet clutch dct, dry clutch dct, and a transmission cooler works in real life, it sort of is a self-answering question.
I never said anything about keeping the clutch cooler with the exception of trying to hold the car at a stop on a hill without the brake applied. YOU brought in the clutches, not I. You are the one showing your total ignorance here. Like I said, you must understand what you read and look for what is actually being asked. Nice try though I will give you credit. And remember, I'm talking about a cooler for gearbox in the transmission and NOT the clutchpack. HUGE difference
