3.6 TRANSMISSION SIMULATOR (MILLER
TOOL #8333) AND FWD ADAPTER
(MILLER TOOL #8333-1)
NOTE: Remove the starter Relay when using
the transmission simulator - Failure to
remove the Starter Relay can cause a PCM -
No Response condition.
The Transmission
accurately diagnose an intermittent fault.
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
to aid the technician in determining if an internal
transmission problem exists or if the problem re-
sides in the vehicle wiring or Transmission Control
Module (PCM). 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
PCM 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 PCM and not the transmission.
Miller Tool # 8333-1 consists of the adapter
cables and overlay necessary to adapt the simula-
tor to 41TE and 42LE transmissions.

4.0 DISCLAIMERS, SAFETY,
AND WARNINGS
4.1 DISCLAIMERS
All information, illustrations and specifications
contained in this manual are based on the latest
information at the time of publication. The right is
reserved to make changes at any time without
notice.
4.2 SAFETY
4.2.1 TECHNICIAN SAFETY INFORMATION
WARNING: ENGINES PRODUCE CARBON
MONOXIDE THAT IS ODORLESS, CAUSES
SLOWER REACTION TIMES 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
codes or error messages may occur. It is extremely
important that accurate shift lever position data is
available to the PCM. The accuracy of the DTC
