Automatic Transaxle (A/T) Gear Position IndicatorThis indicator in the instrument panel shows which gear has been selected.
Transler Mochanism {4WD}
The transfer mechanism consists of the transfer shaft drive gear. the transfer shaft. the transfer drive gear, the transfer driv-en gear shaft, and the companion flange, The transfer mechanism assembly is on the rear side ot the transmission. besidethe differential. The transfer shaft drive gear on the final driven gear drives the transfer shaft driven qear. power is transmit-ted to the rear differential via the transfer shaft and the Drooeller shaft.
Clutches
The four-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears.When the hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs andsteel plates together, locking them so they don't slip. Power is then transmifted through the engaged clutch pack to its hu$mounted gear. When hydraulic pressure is bled from the clutch pack, the piston releases the friction discs and steel plates, andthey are free to slide past each other. This allows the gearto spin independently on its shaft, transmitting no power.
lst Clutch
The 1st clutch engages/disengages lst gear, and is located at the end ofthe mainshaft, just behind the end cover.The 1st clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.
lst-hold Clutch
The 1st-hold clutch engages/disengages 1st-hold or E position, and is located at the middle of the sub-shaft. The 1st-holdclutch is supplied hydraulic pressure by its ATF feed pipe within the sub-shaft.
2nd Clutch
The znd ciutch engages/disengages 2nd gear, and is located at the middle of the mainshaft. The 2nd clutch is joined back-to-back to the 4th clutch. The 2nd clutch is supplied hydraulic pressure through the mainshaft by a circuit connected to theinternal hydraulic circuit.

The power flow when decelerating is as follows:
Rolling resistance trom the road surface goes through the tront wheels (and rear wheels: 4WD) to the final drive gear.
then to the sub-shaft lst gear via the 4th gear. and 1st-hold clutch which is applied during deceleration.
The one-way clutch is free because the application of torque is reversed.
The counterforce conveyed to the countershaft 4th gear turns the sub-shaft 4th gear via the mainshaft 4th gear. Since
hydraulic pressure is also applied to the 1st clutch. counterforce is also transmitted to the mainshaft. As a result,
engine braking can be obtained with'lst gear.
NOTE: The illustration shows the 4WD automatic transmission; power flow of the 2WD automatic transmission is identi-
cal to the 4WD except tor parts related to the transfer assembly.
