TRANSMISSION CONTROL SYSTEM (4L30–E)7A1–9
Winter Drive Mode
1.Operation
The winter switch will operate when switched on after
all of the following conditions are present:
a. The gear select position is “D”, “N”, “R” and “P”
range.
b. Vehicle speed is 7 mph (11 km/h) or less.
c. Transmission oil temperature is 120
C (248F) or
less.
d. Kickdown switch is off.
e. Accelerator opening is at 8% or less.
2.Cancel Release
1. Cancellation by driver
a. Turning off the winter drive mode switch
b. Shifting select position to “3”, “2”, or “L” (Winter
drive mode is not canceled by selecting “D”, “N”,
“R”, or “P”)
c. Ignition key is turned off.
2. Automatic cancellation
a. When vehicle runs at 21mph (34 km/h) or more
for 1 second or more
b. When transmission oil temperature reaches
140
C (284F) or above
NOTE: The mode returns to normal drive mode or power
drive mode after the winter drive mode is canceled.
Backup Mode
If a major system failure occurs which could affect safety
or damage the transmission under normal vehicle
operation, the diagnostic system detects the fault and
overrides the Powertrain Control Module (PCM).
The “CHECK TRANS” light flashes to alert the driver, and
the transmission must be manually shifted as follows:
Select lever position
Gear Ratio Selected
D4 (Fourth)
Manual 34 (Fourth)
Manual 23 (Third)
Manual L1 (First)
RReverse
Shifts are firmer to prevent clutch slip and consequent
wear. The fault should be corrected as soon as possible.

General Description
The meter assembly has the speedometer, tachometer,
engine coolant temperature gauge, fuel gauge and
warning/indicator lights. In addition, the meter assembly
containing TOD (Torque on Demand) has the TOD
indicator light, or the meter assembly not containing TOD
has the voltmeter and oil pressure gauge instead of the
TOD indicator.
