Overdrive gear will follow the standard progression. Reverse gear isin the left-most position and forward.3.2 Compound Range Patter

6、nProgression is from the left to right with successively higher gearing in lowrange, until the highest gear is reached. A low to high range shift is then accomplished by means of a rangeshift control, followed by an exact repeat of the initial shift pattern starting from the “first” position.3.2.1 R
