I'm not sure that is true - I have a 4 spd in my 75 K25 & its a NP203. It's been converted to part time like it should have been in the first place, but none the less a 203. I would think the confusion would be with the 205 & 208 since thay have the same shift patterns - the 203 has from front to back: Low Lock, Low, N, Hi, Hi Lock. Just sharing what little I know.
