TRANSMISSION SIMULATOR (MILLER
TOOL #8333) AND ELECTRONIC
TRANSMISSION ADAPTER KIT
(MILLER TOOL #8333-1A)
NOTE: Remove the starter Relay when using
the transmission simulator
•
Failure to remove the Starter Relay can
cause a PCM - No Response condition.
•
The removal of the Starter Relay will also
prevent the engine from starting in gear.
•
The
Transmission
Simulator
will
not
accurately diagnose intermittent faults.
The transmission simulator, simply put, is an
electronic device that simulates the electronic func-
tions of any EATX or NGC controlled transmission.
The transmission Simulators basic function is to
aid the technician in determining if an internal
transmission problem exists or if the problem re-
sides in the vehicle wiring or control module. It is
only useful for electrical problems. It will not aid in
the diagnosis of a failed mechanical component,
but it can tell you that the control module 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. A “known good vehicle” would 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 (‘‘P’’ led 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 control module and not the transmission.
Miller Tool # 8333-1A consists of the adapter
cables and overlay necessary to adapt the 8333
simulator to TE/AE/LE/RLE transmissions.

DISCLAIMERS
All information, illustrations and specifications
contained in this manual are based on the latest
information available at the time of publication.
The right is reserved to make changes at any time

SAFETY

TECHNICIAN SAFETY INFORMATION
WARNING: ENGINES PRODUCE CARBON
MONOXIDE THAT IS ODORLESS, CAUSES
SLOWER REACTION TIME, AND CAN LEAD
TO SERIOUS INJURY. WHEN THE ENGINE IS
OPERATING, KEEP SERVICE AREAS WELL
VENTILATED OR ATTACH THE VEHICLE
EXHAUST SYSTEM TO THE SHOP EXHAUST
REMOVAL SYSTEM.
Set the parking brake and block the wheels
before testing or repairing the vehicle. It is espe-
cially important to block the wheels on front-wheel
drive vehicles: the parking brake does not hold the
drive wheels.
Some operations in this manual require that
hydraulic tubes, hoses, and fittings, disconnected
for inspection or testing purposes. These systems,
when fully charged contain fluid at high pressure.
Before disconnecting any hydraulic tubes, hoses
or fittings, be sure that the system is fully depres-
surized.
When servicing a vehicle, always wear eye pro-
tection and remove any metal jewelry such as
watchbands or bracelets that might make an inad-
vertent electrical contact.
When diagnosing a Transmission system prob-
lem, it is important to follow approved procedures
where applicable. These procedures can be found in
the service information. Following these proce-
dures is very important to the safety of individuals
performing diagnostic tests.
4.2.2
VEHICLE PREPARATION FOR
TESTING
Make sure the vehicle being tested has a fully
charged battery. If it does not, false diagnostic
DTC’s or error messages may occur. It is extremely
important that accurate shift lever position data be
available to the PCM. The accuracy of any DTC
found in memory is doubtful unless the Shift Lever
Test, performed on the DRBIII
t Scan Tool, passes
without failure.
4.2.3
SERVICING SUB-ASSEMBLIES
Some components of the Transmission system
are intended to be serviced in assembly only. At-
tempting to remove or repair certain system sub-
components may result in personal injury and/or
improper system operation. Only those compo-
