Isuzu KB P190. Manual - part 1071

CONSTRUCTION AND FUNCTION  7A1-45 

4th Gear (O/D) in D Position 
The driving force from the input shaft is transmitted to the rear sun gear and reverse & high clutch drum.  
Since the 2-4 brake is engaged, the front sun gear is fixed.  In addition to this the high clutch is engaged.  As 
a result, the front pinion gear rotates itself together with other gears clockwise.  This rotation increases the 
speed of rotation of the front internal gear and is transmitted to the output shaft.
