That small shaft is the input shaft. It is splined into internal parts inside the transmission. Only one end of it will fit into the transmission, as the splines on each end are different from each other. It should fit in easily, and you may have to turn it a bit to line up with the internal spline. If you removed it completely, are you sure you put the correct end into the transmission? It should protrude about an inch from the larger spline.
