The transmission illustration is of a standard 4 speed.
I once got a call from someone who was parting out a 250S sedan, and he claimed it had a 5 speed trans. I told him to bring the trans. and linkage over to my shop and I would give him $200 for it. The next morning he shows up with a trans. on the back of his tow truck. It was just a stock 4 speed but had a 5 speed shift knob on the linkage. At the time I had a half a dozen old 4 speeds laying around and didn't need another. I had no idea that he had driven in from Belton, MO to Kansas City, so he was kinda angry about the situation.
