Automatic Transmission Fluid
It is not necessary to check the transmission uid
level. A transmission uid leak is the only
reason for uid loss. If a leak occurs, take your
vehicle to your GM dealer service department and
have it repaired as soon as possible.
Change the uid and lter at the intervals listed in
Additional Required Services on page 465, and
be sure to use the transmission uid listed in
Recommended Fluids and Lubricants on page 473.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 473.
How to Reset the Change Transmission
Fluid Message and the Transmission
Fluid Indicator
After the transmission uid has been changed, the
Change Trans Fluid message and the transmission
uid life indicator must be reset. To reset the
message and indicator, use one of the following
procedures:
Base Audio System
Press the CLR (Clear) button located to the right of
the Driver Information Center (DIC) display to
acknowledge the CHANGE TRANS FLUID
message. This will clear the message from the
display and reset it.
353

To reset the transmission uid life indicator, use the
following steps:
1. Press the up or down arrow on the INFO
(Information) button located to the right of the
DIC display to access the DIC menu.
2. Once the XXX% TRANS FLUID LIFE menu
item is highlighted, press and hold the CLR
button.
The percentage will return to 100, and the
transmission uid life indicator will be reset.
3. Repeat the steps if the percentage does not
return to 100.
Navigation System
If your vehicle has a navigation system, see your
Navigation System Manual for instructions on
how to acknowledge the Change Trans Fluid
message and reset the transmission uid
life indicator.
Manual Transmission Fluid
When to Check Manual Transmission
Fluid
It is not necessary to check the manual
transmission uid level. A transmission uid leak is
the only reason for uid loss. If a leak occurs, take
the vehicle to your GM dealer service department
and have it repaired as soon as possible.
How to Check Manual Transmission
Fluid
Because this operation can be difficult, you may
choose to have this done at your GM dealer
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that
some of the uid could come out and fall on hot
engine parts or exhaust system parts, starting a
re. Too little uid could cause the
transmission to overheat. Be sure to get an
accurate reading if you check your
transmission uid.
354

Check the uid level only when your engine is off,
the vehicle is parked on a level place and the
transmission is cool enough for you to rest your
ngers on the transmission case.
To check the uid level, do the following:
1. Remove the ller plug.
2. Check that the lubricant level is up to the
bottom of the ller plug hole.
3. If the uid level is good and your vehicle is a
CTS, replace the gasket and reinstall the ller
plug. If the uid level is good and your
vehicle is a CTS-V, apply LOCTITE
®#516 or
equivalent sealant to the threads and then
reinstall the ller plug.
With either vehicle, be sure the plug is fully
seated. If the uid level is low, add more uid
as described in the next steps.
How to Add Manual Transmission Fluid
Here is how to add uid. SeeRecommended
Fluids and Lubricants on page 473to determine
which type of uid to use.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only
enough uid to bring the uid level up to
the bottom of the ller plug hole.
3. If your vehicle is a CTS, replace the gasket
and reinstall the ller plug. If your vehicle is a
CTS-V, apply LOCTITE
®#516 or equivalent
sealant to the threads and then reinstall
the ller plug.
Again, with either vehicle, be sure the plug is
fully seated.
355

(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as high performance operation.
If you do not use your vehicle under any of these
conditions, the uid and lter do not require
changing.
(i)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 356 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)If using DOT-4 brake uid only: Drain, ush,
and rell brake hydraulic system at a regular
maintenance service (IorII) every two years.
This service can be complex; you should have
your dealer perform this service. See Brakes
on page 371.(k)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked. Add uid
if needed.
(l)Change uid if the vehicle is used for high
performance operation.
(m)Change uid whenever the vehicle has been
driven for 3,000 miles (5 000 km) with the
transmission temperature at 290°F (143°C) or
higher without using an auxiliary uid cooler.
See Message Center (CTS-V) on page 215 and
Transmission Fluid Hot Message on page 219.
(n)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(p)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.

Lubricants
Fluids and lubricants identied below by name,
part number, or specication can be obtained from
