It's a fiberglass scoop that fits inside the grill and over the trans cooler to direct more air through the cooler. I've been running one for over a year now and it makes a noticable reduction in trans temperature. Phone number I have is 847-367-9770. Edited by: Idle_Chatter
I have one also. they are handmade and fit well. simple install. it seems to help, but only when i'm moving at a decent speed. not much good in stop and go traffic, but it helps on the highway.
