Anyone added external cvt cooler if yes which type, shop and cost?

Have been reading and getting conflicting views ie some workshop adv to get with adapter or and the install will be direct between transmission and external cooler without going thru the radiator but will be costly.

Another will be to trans to radiator to external cooler then back to radiator then end up into trans. This option is cheaper as there's no adapter needed.

Which provides better cooling?

Nope just wanna take precautions to maximise the lifespan as will be keeping the car for more than 7 yrs as it’ll be driven by kids
