Abstract
An apparatus for installation of a transmission fluid pan drain provides upper and lower deformation plates attachable to opposed sides of the transmission fluid pan by a threaded stud. The upper and lower deformation plates are sized and shaped so that when torque is applied to nuts carried on the threaded stud the plates are forced together, thereby deforming the transmission fluid pan, causing a depression or dimple in the fluid pan. After removing the deformation plates and stud, a hollow bolt is attachable in a fluid-tight manner to the transmission fluid pan in a manner wherein an upper end is carried above the pan and a lower threaded end is carried below the pan. An end cap is attachable to the threaded lower end of the hollow bolt, allowing transmission fluid to be drained by removing the end cap.
