Models in the 15-speed series have fifteen forward speeds and three reverse, consisting of a five-speed front section and a three-speed auxiliary section. For highway operation, the five speeds in the front section are used once in LO Range and once again in HI Range. You use the easy, one shift lever, Roadranger®  repeat shift pattern. LO Range and HI Range are selected with the Range Control Knob/Range Preselection Lever. It is used once during the upshift sequence and once during the downshift sequence. Always preselect the range shift as shown in the detailed instructions. After preselection, the transmission automatically makes the synchronized range shift as the shift lever passes through neutral. 

The Deep Reduction ratios are selected by the Deep Reduction Lever of the dash- mounted valve or the Deep Reduction Button of the Master Control Valve on the shift lever. The “IN”/FORWARD position selects the Deep Reduction ratios; the  “OUT”/REARWARD position is used for all other shifting. The Deep Reduction ratios overlap some of the ratios in LO Range. However, the transmission can be shifted progressively from Deep Reduction, to LO Range, and to HI Range to give twelve progressive speeds.

General Transmission Notes:

1. Length Listed lengths are installation dimensions from the face of clutch housing to front bottoming surface of companion flange or yoke, except AT-1202 and 2-A-92, which are from bottoming surface of input yoke to bottoming surface of output yoke.
2. Weight Listed weights are without clutch housing, controls and lubricant unless otherwise specified. All weights are approximate. Add 7 lbs. [3.15 kg] to models with an internal oil pump.
