Barely used transmission control module L34T-18-9E1E. I bought it new for +$250 approx 14 months ago, successfully installed and ran it in my daughter’s 2007 Mazda 3 Wagon, and 1,255 miles later the engine head gasket failed and ruined the engine (filled cylinders with water, broke head, bent a couple of rods). I pulled the module, since it was practically new, before the car was hauled to the graveyard. My loss your gain. I guarantee it’s good. (Old module in the pic too)
