SERVICE UPDATE
SUBJECT:

Service Update for Inventory and Customer Vehicles
Transfer Case Oil Delivery Tube Installed Incorrectly
Expires with Base Warranty

MODELS:

2013 Cadillac ATS AWD

This service update includes vehicles in dealer inventory and customer vehicles that
return to the dealership for any reason. This bulletin will expire at the end of the involved
vehicle's New Vehicle Limited Warranty period.

PURPOSE
This bulletin provides a service procedure to inspect and, if necessary, replace the transfer case
oil delivery tube on certain 2013 model year Cadillac ATS AWD vehicles. On some vehicles,
the tube may not be fully seated and a leak could develop.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System –
Investigate Vehicle History Application. Dealership technicians should always check this site to
confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is
important to routinely use this tool to verify eligibility because not all similar vehicles may be
involved regardless of description or option content.
Additionally, a list of involved vehicles currently in dealer inventory is available on the “Service
Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (US) or attached
to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that
return for service, for any reason, and are still covered under the vehicle's base warranty should
also be checked for vehicle eligibility.

The lower or bottom end of the tube (1) is suspect for an incomplete assembly into the quick connect
fitting. Visually inspect it using a telescoping dentist mirror. The upper or top end of the tube (2) is not
suspect. Do NOT inspect the upper or top end of the tube (2). Portion “A” of the illustration shows an
incorrectly installed transfer case oil delivery tube. The lower transfer case oil delivery tube end is
unseated. The tube flare end is exposed and visible. Portion “B” of the illustration shows a correctly
installed transfer case oil delivery tube. The tube end is fully seated and the tube fitting clip is fully
engaged.

3. Determine if the transfer case oil delivery tube is installed correctly by performing a visual
inspection of the lower or bottom end of the tube using a mirror. Ensure the lower end of the
transfer case oil delivery tube is fully seated and the tube fitting clip is fully engaged and
secure on the tube fitting. If the tube flare or yellow line above the flare is visible, the tube is
NOT installed correctly. Tug on the lower end of the tube to ensure the tube is installed
correctly. Inspect the area around the transfer case oil delivery tube for evidence of a fluid
leak.


If the transfer case oil delivery tube is installed correctly, no further action is required.
Lower the vehicle. Refer to Lifting and Jacking the Vehicle in SI.



If the transfer case oil delivery tube is NOT installed correctly, proceed to step 4.

4. Remove the transfer case oil delivery tube from the transfer case. Use a hook type tool,
magnet and pliers to remove the fitting clip.
5. Remove the transfer case fill plug.


If the fluid level is to the bottom of the fill plug hole, proceed to step 6.

Note: Use mechanic’s wire (or equivalent) to make a transfer case fluid level tool. Cut a 305 mm
(12 in) piece of wire. Measure 50.8 mm (2 in) from one end of the wire inward and make a mark
using a file or cutting tool. Bend the wire on a 90 degree angle at the 50.8 (2 in) mark. Using a
file or cutting tool, mark 20 mm (0.8 in) up from the end of the wire with the 90 degree bend.
Insert the bent end of the wire into the fill plug hole.


If the fluid level is higher than the 20 mm (0.8 in) mark on the fluid level tool, add fluid
until the level is to the bottom of the fill plug hole. Proceed to step 6 after the transfer
case fluid level has been filled to the correct level.



If the fluid level is equal to or lower than 20 mm (0.8 in) mark on the fluid level tool,
remove and replace the transfer case. Refer to Transfer Case Assembly Replacement in
SI.

6. Install the fill plug and tighten it to 15 Nm (11 lb-ft).
7. Install a new transfer case oil delivery tube.
7.1 Install the new fitting clips.
7.2 Lube the ends of the tube with transfer case fluid.
7.3 Center the tube ends into fitting.

DEALER PROGRAM RESPONSIBILITY
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your
facility for service in the future, and the vehicle is still covered under the New Vehicle Limited
Warranty, you must take the steps necessary to be sure the service update correction has been
made before selling or releasing the vehicle.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
