Exactly how does the automatic clutch and the gears work on the LT-F250 4x4. Do you put it in gear and open the throttle to get moving? Then what do you do to change gears and gear range while on the move?

I have decided that I want to get an early quadrunner, but I have seen some posts that refer to different models. Was there a 2-stroke and 4-stroke version? Was there a 4x2 and a 4x4 version?  Was there an automatic and manual version? Was there a diff lock and non-diff lock version? What options were available for the gearbox? When did the LT-F250 get named an Ozark or is it different again?

I am getting confused and it is difficult to find definitive answers. Can anybody help???
