DESCRIPTION AND OPERATION

Automatic Transaxle External
Controls

The motor/transaxle is switched into different modes
by moving the shift lever into the desired position.
A shift cable connects the shift lever to the
motor/transaxle. A digital transmission range (DTR)
sensor is mounted on the LH side of the
motor/transaxle. The DTR sensor moves in direct
relation to the shift lever. This sensor provides the
traction inverter module (TIM) with gear selection
information. The sensor is adjustable and must be
realigned whenever the sensor is removed.
