E Po3ition
Hydraulic pressure is not applied to the clutches. Power is not transmitted to the countershaft.
The countershaft is locked by the park pawl interlocking the park gear,
E Position
Engine power transmitted from the torque converter drives the mainshaft. but hydraulic pressure is not applied to the
clutches. Power is not transmitted to the countershaft. The countershaft 4th gear is engaged with the reverse selector hub
and the countershaft by the reverse selector, when the shift lever is shifted in E position from E or E position. The
countershaft reverse gear is engaged when shifted from E position.
NOTE; The illustration shows the 4WD automatic transmission; oower flow of the 2WD automatic transmission is identi-
cal to the 4WD exceDt for oarts related to the transfer assemblv.

Electronic Control System
The electronic control svstem consists of a Powertrain Control Module (PCM), sensors, a linear solenoid, and four solenoid
valves. Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is located
below the dashboard, under the kick panel on the passenger's side.
