Nick,
If the trans is out of the car, rotate the imput shaft and count the number of turns it takes for the axel to make one revolution.The more revolutions the imput shaft makes is the lower the gear. If the trans is installed, mark the pressure plate and do the same with the clutch disengaged. Not an easy task, but you will know right away. An alternative with the trans in the car, is to move the pressure plate the same number of clicks(teeth) for each gear, measure the arc the axel goes through. Smaller arc=lower gear. Of course reverse is the turn in the opposite direction.
I believe that is correct.
