3.2.2 TRANSMISSION OPERATION AND
SHIFT SCHEDULING AT VARIOUS
OIL TEMPERATURES.
The transmission covered in this manual has
unique shift schedules depending on the tempera-
ture of the transmission oil. The shift schedule is
modified to extend the life of the transmission while
operating under extreme conditions.
The oil temperature is measured with a Temper-
ature Sensor on the 41TE/AE transmission. The
Temperature Sensor is an integral component of the
Transmission Range Sensor (TRS). If the Tempera-
ture Sensor is faulty, (DTC P1799(74)) the trans-
mission will default to a calculated oil temperature.
Oil temperature will then be calculated through a
complex heat transfer equation which uses engine
coolant temperature, battery/ambient temperature,
and engine off time from the Body Control Module
(BCM). These inputs are received from the PCI bus
periodically and used to initialize the oil tempera-
ture at start up. Once the engine is started, the
TCM updates the transmission oil temperature
based on torque converter slip speed, vehicle speed,
gear, and engine coolant temperature to determine
an estimated oil temperature during vehicle opera-
tion. Vehicles using a calculated oil temperature
track oil temperature reasonably accurate during
normal operation. However, if a transmission is
overfilled, a transmission oil cooler becomes re-
stricted, or if a customer drives aggressively in low
gear, the calculated oil temperature will be inaccu-
rate. Consequently the shift schedule selected may
be inappropriate for the current conditions. The key
highlights of the various shift schedules are as
follows:
Extreme Cold:Oil temperature at start up below
-26.6C (-16ÉF)
> Goes to a Cold schedule above -24C (-12ÉF) oil
temperature
> Park, Reverse, Neutral and 2nd gear only (pre-
vents shifting which may fail a clutch with fre-
quent shifts)
Cold:Oil temperature at start up above -24C
(-12ÉF) and below 2.2C (36ÉF)
> Goes to a Warm schedule above 4.4C (40ÉF) oil
temperature
> Delayed 2-3 upshift approximately 35-50 Km/h
(22-31 MPH)
> Delayed 3-4 upshift 72-85 Km/h (45-53 MPH)
> Early 4-3 coastdown shift approximately 48
Km/h (30 MPH)
> Early 3-2 coastdown shift approximately 27
Km/h (17 MPH)> High speed 4-2, 3-2, 2-1 kickdown shifts are
prevented
> No EMCC
Warm:Oil temperature at start up above 2.2C
(36ÉF) and below 27C (80ÉF)
> Goes to a Hot schedule above 27C (80ÉF) oil
temperature
> Normal operation (upshifts, kickdowns, and
coastdowns)
> No EMCC
Hot:Oil temperature at start up above 27C (80ÉF)
> Goes to a Overheat schedule above 115C (240ÉF)
oil temperature
> Normal operation (upshifts, kickdowns, and
coastdowns)
> Full EMCC, No PEMCC except to engage
FEMCC
(Except at closed throttle at speeds above 113-133
Km/h (70 - 83 MPH)
Overheat:Oil temperature above 115C (240ÉF) or
engine coolant temperature above 118C (244ÉF)
> Goes to a Hot below 110C (230ÉF) oil temperature
or a Super Overheat above 115C (240ÉF) oil
temperature
> Delayed 2-3 upshift 40-51 Km/h (25-32 MPH)
> Delayed 3-4 upshift 66-77 Km/h (41-48 MPH)
> 3rd gear FEMCC from 48-77 Km/h (30-48 MPH)
> 3rd gear PEMCC from 43-50 Km/h (27-31 MPH)
Super Overheat:Oil temperature above 127C
(260ÉF)
> Goes back to a Overheat below 115C (240ÉF) oil
temperature
> All a Overheat shift schedules features apply
> 2nd gear PEMCC above 35 Km/h (22 MPH)
> Above 35 Km/h (22 MPH) the torque converter
will not unlock unless the throttle is closed (i.e. at
80 Km/h (50 MPH) a 4th FEMCC to 3rd FEMCC
shift will be made during a part throttle kick-
down or a 4th FEMCC to 2nd PEMCC shift will
be made at wide open throttle) or if a wide open
throttle 2nd PEMCC to 1 kickdown is made.
Causes for operation in the wrong tempera-
ture shift schedule:
Extreme Cold or Cold shift schedule at start up:
> Temperature Sensor circuit.
Overheat or Super Overheat shift schedule after
extended operation:
> Operation in city traffic or stop and go traffic
> Engine idle speed too high
> Aggressive driving in low gear

GENERAL INFORMATION

Transmission Effects and possible causes:
Scenario 1)- All PRNDL lights stay illuminated
indefinitely in Park following a Key start.
> Wrong Part Number TCM for application
> TRS connector not plugged in
> C1 through C4 (T1, T3, T41, or T42) circuits are
either open, shorted to ground, or shorted to 12
volts.
> PCI bus failure (Open or shorted resulting in no
communication to BCM or Cluster)
> TRS
> TCM
> BCM
Scenario 2)-9P9is indicated following a key start
but all PRNDL lights illuminate in9N9following a
shift from9R9to9N9. If PRNDL lights illuminate in
9N9and shifter is moved directly into939or9L9
position without pausing in9OD9, then the9OD9
position shift schedule and electronic display will
indicate9OD9until the shifter is shifted into the
9OD9position and held for at least 3 seconds.
> Worn Manual Lever (Rooster Comb). Check for
heavy wearing by TRS switch contacts
> Intermittent C1 through C4 (T1, T3, T41 or T42)
circuits. Check for corrosion, terminal push-outs
or spread terminals at 60-way and/or TRS switch
10-way connector
> TRS
> TCM
> BCM
Scenario 3)- If the invalid code happened while
operating in the939or9L9position, then the939or
9L9shift schedule and electronic display will be
frozen (regardless of whether9OD9,939or9L9is
selected) until the shifter is moved to the9N9
position (all PRNDL lights will illuminate) and
then back to the9OD9position and held there for at
least 3 seconds in order to resume the normal9OD9
shift schedule and electronic display.
> Intermittent C1 through C4 (T1, T3, T41 or T42)
circuits. Check for corrosion, terminal push-outs
or spread terminals at 60-way and/or TRS con-
nector
> TRS
> TCM
> BCM
These same symptoms may occur without the
code P0705(28) getting set. It is possible that the
invalid code that was sensed by the TCM only
occurred once or twice during the given ignition key
start and/or did not last for longer than 0.1 second.Name of code:P0120(29) - Throttle Position Sen-
sor Signal
When monitored:Whenever the engine is run-
ning.
Set condition:This code is set if the throttle angle
goes out of range or if throttle angle changes
abruptly (ie: faster than the throttle body motion
could occur)
Theory of operation:The Transmission Control
Module (TCM) receives the throttle position signal
from the Throttle Position Sensor (TPS) through a
wire spliced into the TPS circuit to the PCM. The
TPS has a 5-volt pull up supplied from the Power-
train Control Module (PCM). The signal is checked
for out-of-range as well as an intermittent (exces-
sive signal changes).
Transmission Effects:Extremely erratic trans-
mission shifting with an intermittent TPS signal
just prior to setting the code. If the intermittent
does not last long enough to set the code, the
customer will say that the transmission violently
hunts between gears. The TCM will use a calcu-
lated throttle angle supplied by the PCM over the
PCI bus. If the PCI bus is unavailable, the TCM will
use a default throttle angle of 24 degrees for the key
start in which the code was set. The TCM will try to
use the TPS signal again on the next key start.
Possible causes:
> Open or shorted TPS signal and/or ground cir-
cuits
> TCM connector problems
> TPS or TPS connector (Check PCM DTC's)
> PCM
> TCM
Name of code:P1787(31) - OD Hydraulic Pressure
Test Failure
P1788(32) - 2-4 Hydraulic Pressure Test Failure
P1789(33) - OD/2-4 Hydraulic Pressure Test Failure
When monitored:In 1st, 2nd, or 3rd gear with
engine speed above 1000 RPM shortly after a shift
and every minute thereafter.
Set condition:Immediately after a shift into 1st,
2nd, or 3rd gear, with engine speed above 1000
RPM, the TCM momentarily turns on element
pressure to the 2-4 and/or OD clutch circuits to
identify that the appropriate pressure switch
closes. If the pressure switch does not close it is
tested again. If the switch does not close the second
time, the appropriate code is set.
Theory of operation:The Transmission Control
Module (TCM) tests the OD and 2-4 pressure
switches when they are off (OD and 2-4 are tested in
1st gear, OD in 2nd gear, and 2-4 in 3rd gear). The
test verifies that the switches are operational. The
TCM verifies that the switch closes when the cor-

3.5.1 DRBIIITDOES NOT POWER UP
(BLANK SCREEN)
If the LED's do not light or no sound is emitted at
start up, check for loose cable connections or a bad
cable. Check the vehicle battery voltage. A mini-
mum of 11 volts is required to adequately power the
DRBIIIt.
If all connections are proper between the DRBIIIt
and the vehicle or other devices, and the vehicle
battery is fully charged, an inoperative DRBIIIt
may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate Body
Diagnostic manual.
3.5.2 DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the
display. Adjust the contrast to compensate for this
condition.
3.6 TRANSMISSION SIMULATOR
(MILLER TOOL # 8333) AND FWD
ADAPTER (MILLER TOOL #8333-1)
The transmission simulator, simply put, is an
electronic device that simulates the electronic func-
tions of any EATX controlled transmission (41TE,
42LE, 45RFE, and 545RFE). It's basic function is toaid the technician in determining if an internal
transmission problem exists or if the problem re-
sides in the vehicle wiring or Transmission Control
Module (TCM). It is only useful for electrical prob-
lems. It will not aid in the diagnosis of a failed
mechanical component, but it can tell you that the
TCM and wiring are working properly and that the
problem is internal.
The ignition switch should be in the lock position
before attempting to install the simulator. Follow
all instructions included with the simulator. If the
feedback from the simulator is in doubt, you can
verify it's operation by installing it on a known good
vehicle. A9known good vehicle9would be defined as
a vehicle that does not set any DTC's and drives and
shifts as expected.
One important point to remember is that the
Simulator receives it's power from the Trans Relay
Output circuit. If the transmission system is in
Limp-in (Relay open), the simulator will not oper-
ate. This is not really an indication of a problem,
but an additional symptom. If the simulator does
not power up (9P9led lit), this is an indication that
the problem is still present with the simulator
hooked up. This indicates that the problem is in the
wiring or TCM and not the transmission.
Miller Tool # 8333-1 consists of the adapter cables
and overlay necessary to adapt the simulator to
41TE and 42LE transmissions.
