Test Modes
MIT test modes include:
•BluetoothTestModes
– Pairs with vehicle (Hands-free cell phone)
– Places a simulated test call
– Confirmation message of proper Bluetooth
system operation
– Streaming audio from a mobile device
(currently not available on Camaro and Sonic)
– Confirmation message of proper Bluetooth
streaming audio system operation
• USBTestModes:
– Connection detection
– Confirmation message of proper USB system
operation
• AuxiliaryJackTestModes:
– Connection detection
– Confirmation message of proper auxiliary jack
system operation
The MIT is powered by a USB cable. The included
USB power adapter can be used to power the
MIT on vehicles that do not have a USB port. The
included RCA adapter cable is used to test the
audio (Line-In) functions on vehicles using that
connection instead of the 3.5mm auxiliary jack.
User’s Guide
The user’s guide for the MIT is available on the
tool in a pdf format. To access the pdf, connect
the USB cord from the MIT into a computer and
press the TEST SELECTOR button until the USB
LED indicator illuminates. The computer will
recognize a new device and allow access to the
folder where the user’s guide is stored. The guide
can be viewed or printed from the folder.

Transmission Oil Cooler Flow
Check and Flush Test
When performing a transmission oil cooler flow check and flush test on the
2003-2010 Vibe, 2002-2007 VUE, 2003-2004 ION and 2008-2009 Astra,
essentialtoolJ-45096,TransowTransmissionCoolerFlusher,shouldbe
used. This procedure applies to both automatic and manual transmissions that
do not use DEXRON
®
-III or DEXRON
®
-VI transmission fluid.
A plugged or restricted transmission oil cooler and pipes may lead to
insufficient transmission lubrication, elevated operating temperatures, and
ultimately, premature transmission failure. To prevent this, follow the transmis-
sion oil cooler flow check and flush test procedures outlined in the appropriate
Service Information and #PI0537.
The procedure involves:
• Machineset-up
• Determiningtheminimumowrate
• Backushing
• Forwardushing
• Flowtesting
• Coderecording
• Cleanup
TheJ-45096transmissionoilcooling
system flush and flow test tool replaces
othercoolerushingtools.TheJ-45096
tool is a self-contained unit using a 12-volt
flow meter, shop air supply and DEXRON-
VI automatic transmission fluid (ATF).
TIP: Use only DEXRON-VI automatic
transmissionuidintheJ-45096tool.Whilethetransmissionuidrequirement
for the listed vehicles is different than DEXRON-VI, flushing the cooler with
DEXRON-VI is an acceptable service procedure. Very little fluid remains in the
cooler after the flush procedure and the residual DEXRON-VI ATF in the cooler
is compatible with the listed vehicles’ transmission fluid.
When using the tool in the flush mode, ATF is cycled through the transmission
oil cooling system. High-pressure air is automatically injected into the fluid
stream, adding agitation to the ATF oil, to help remove contaminated oil and
debris.
In the flow mode, the electronic flow meter measures the flow capability of the
transmission oil cooling system. The display indicates the ATF oil flow rate in
gallons per minute (GPM) along with the amount of ATF in the supply vessel,
supply vessel ATF temperature, machine cycles and the operating mode. The
requiredminimumATFoilowratereadingisdirectlyrelatedtothesupplyoil
temperature.
In the code mode, a random, encrypted code is generated that can be used for
verification of flow test results. After completing the flush and flow testing, the
testing flow rate (in GPM), temperature, cycle number and seven-digit flow
code must be recorded on the repair order.
CurrentessentialcoolerlineadaptersareusedtoconnecttheJ-45096tothe
transmission oil cooler lines, which enables the tool to adapt to most GM pas-
senger cars and light-duty trucks. If an adapter is not available, one can be
made using a barbed hose connector and a rubber hose obtained locally.
For information about vehicles with automatic transmissions that use
DEXRON-III or DEXRON-VI transmission fluid, refer to Bulletin
#02-07-30-052H.
