DESCRIPTION AND OPERATION (Continued)
LOCK or ACCESSORY position, unless shifter is in
the PARK position.
GEARSHIFT AND PARKING LOCK CONTROLS
The transaxle is controlled by a lever type gear-
shift incorporated within the floor shift mechanism.
The standard gearshift control has six selector lever
positions: P (park), R (reverse), N (neutral), and D
(drive), and L (low). The parking lock is applied by
moving the selector lever past a gate to the P posi-
tion. Do not apply the parking lock until the
vehicle has stopped; otherwise, a severe ratchet
noise will occur.

TRANSMISSION RANGE SENSOR

All vehicles are equipped with a transmission
range sensor that is located on top of the valve body.
This sensor replaces the gear position switch and the
transmission range switch. This sensor will allow for
accurate transmission gear position measurement.
This sensor is similar to the MVLPS that is currently
on the 42LE transaxle.
To service the transmission range sensor (TRS),
you must remove the valve body. For repair proce-
dures, refer to the Removal and Installation section
within this group.

TRANSMISSION TEMPERATURE SENSOR

Located within the Transmission Range Sensor is a
transmission temperature sensor. This sensor is used
to measure the transmission fluid sump temperature.
The transmission temperature sensor is serviced
with the TRS as a unit.

AUTOSTICK

OPERATION
Autostick is a driver–interactive transaxle feature
that offers manual gear shifting capability. When the
shifter is moved into the Autostick position, the tran-
saxle remains in whatever gear it was using before
Autostick was activated. Moving the shifter to the
left (towards the driver) causes a downshift and mov-
ing to the right (towards the passenger) causes an
upshift. The instrument cluster will illuminate the
selected gear. The vehicle can be launched in 1st,
2nd, or 3rd gear while in the Autostick mode. The
speed control is operable in 3rd and 4th gear Auto-
stick mode. Speed control will be deactivated if the
transaxle is shifted to 2nd gear. Shifting into OD
position cancels the Autostick mode, and the tran-
saxle resumes the OD shift schedule.
AUTOMATIC OVERRIDES
For safety, durability, and driveability, some shifts
are executed automatically or prevented.
AUTOMATIC SHIFTS WILL OCCUR UNDER
THE FOLLOWING CONDITIONS
TYPE OF SHIFT
4-3 coast downshift
3-2 coast downshift
2-1 coast downshift
1-2 upshift
2-3 upshift
4-3 kickdown shift
MANUAL SHIFTS ARE NOT PERMITTED
UNDER THE FOLLOWING CONDITIONS
TYPE OF SHIFT
3-4 upshift
3-2 downshift
2-1 downshift
SHIFT POSITION INDICATOR
The shifter position indicator is located in the
instrument cluster. The shifter position indicator out-
lines with a box the gear position the transaxle man-
ual valve lever is in.
The transmission range sensor (located on the
valvebody) sends a signal to the TCM on the position
of the transaxle manual valve lever. The TCM
receives the switch signal and processes the data.
The TCM sends the Shift Lever Position (SLP) infor-
mation to the BCM via the CCD bus. The BCM then
outlines the appropriate shifter position indicator in
the instrument cluster.
To replace the shifter position indicator, refer to
Group 8E, Instrument Panel And Gauges.

DIAGNOSIS AND TESTING

41TE TRANSAXLE GENERAL DIAGNOSIS

CAUTION: Before attempting any repair on a 41TE
four speed automatic transaxle, check for Diagnos-
tic Trouble Codes with the DRB scan tool. Always
use the Powertrain Diagnostic Test Procedure Man-
ual.
Transaxle malfunctions may be caused by these
general conditions:
• Poor engine performance
