"Cool thing", huh? Bad pun.
Heh, I'm not using the OEM setup anymore; I went aftermarket cooler 'cause I fubar'd up the stock tranny cooler lines when swapping my tranny.
My concern would be bumper-to-bumper traffic. I nearly overheated the engine on a hot day recently - I was in stop-n-go traffic for about a half-hour. (I already know I need a new radiator). The tranny cooler was warmer than usual, but still not too hot to touch. Will the tranny coolers ever get as hot at a stock radiator?
Thanks for your opinion, I always respect and listen to yours. Honestly.
