So I let my friend borrow my truck. He took it hunting and while driving a bunch or weird stuff started happening with the trans. It will not drive in reverse, does not drop into overdrive and drives while in neutral. My friend took the trans pan off and found a small flat piece of metal in the pan shaped like a fat “L”. Anyone reacognize this piece? 2000 Tacoma, a340f trans, 2.7 L engine, 4WD
