A plug for draining fluids from a vehicle transmission fluid pan is described that has an externally threaded tubular valve placed through a port in the transmission fluid pan. The tubular valve is placed through a port in the transmission fluid pan and held in place on the transmission fluid pan by a bolt head on one end of the tubular valve and an internally threaded lock nut screwed onto threads on the outer surface of the tubular valve. There is a seal on the tubular valve between the bolt head and the transmission fluid pan and a seal in the end cap to reduce leakage from the port and the tubular valve. An end cap is threadingly placed on another end of the tubular valve distal the bolt head to selectively allow flow of lubricant through the tubular valve from the transmission fluid pan. There is a retaining spring strap having a loop on one end through which the tubular valve is placed. The other end of the strap is rotatively connected to the end cap to spring and suspend the end cap away from the tubular valve and out of the flow stream of the lubricant flowing from the pan and to keep the end cap from falling into a transmission fluid receptacle or onto the surface below.
