Very few automatic transmission pans come with a drain plug from the factory. So servicing your transmission by removing the transmission pan to drain the fluid can be very messy. Weve got you covered with our Hi-Tek Universal mount transmission pan drain plug. You remove the pan and drill a 1/2-inch hole, then bolt the B&M Drain Plug Kit into the pan. Its that easy, and you eliminate any future messy oil splashes and spills. Note: The plug is non-magnetic.
