TM 9-2520-246-34 (2) High Range. When the transfer is shifted into high range, the synchronizer assembly is moved rearward on the input shaft to engage the input-shaft high-speed gear, which is in mesh with the countershaft high-speed gear. Because the high-speed gear is keyed to the countershaft, power flow is through the countershaft gears to the rear (and front, if lockup assembly is engaged) output shafts and gears. (4) Neutral. A neutral position is provided to allow operation of the gear train when no motion of the vehicle is desired. 4-3. Data.
