Dual Clutch Transmission Fluid
How to Check Dual Clutch Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to the dealer and have it
repaired as soon as possible. The vehicle is not equipped with a
transmission fluid level dipstick. There is a
special procedure for checking and changing
the transmission fluid. Because this
procedure is difficult, this should be done at
the dealer. Contact the dealer for additional
information or the procedure can be found
in the service manual. To purchase a service
manual, see
Publication Ordering
Information 0337.
Caution
Use of the incorrect transmission fluid
may damage the vehicle, and the
damage may not be covered by the
vehicle warranty. Always use the correct
transmission fluid. See Recommended
Fluids and Lubricants 0320.
Change the fluid and external canister filter
at the proper intervals. See Maintenance
Schedule 0316. Be sure to use the correct
fluid. See Recommended Fluids and
Lubricants 0320.
Dual Clutch Transmission Fluid Life
System
When to Change the Dual Clutch
Transmission Fluid
This vehicle has a computer that indicates
when to change the transmission fluid. This
is based on a combination of factors which
include temperature and miles driven. Based
on driving conditions, the mileage at which
a fluid change is indicated can vary
considerably. For the fluid life system to
work properly, the system must be reset
every time the fluid is changed. When the
system has calculated that fluid life has
been diminished, it indicates that a fluid
change is necessary. A CHANGE
TRANSMISSION FLUID SOON message comes
on. Change the fluid as soon as possible
within the next 1 000 km (600 mi). Failure
to change transmission fluid at required
intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will change
the fluid and reset the system. If the system
is ever reset accidentally, the fluid must be
changed 72 000 km (45,000 mi) after the
last fluid change.

When to Replace the Dual Clutch
Transmission Fluid Filter
This vehicle has a computer that indicates
when to change the transmission external
canister fluid filter. This is based on the
number of miles driven as outlined in the
Service and Maintenance section. For the
fluid filter life system to work properly, the
system must be reset every time the filter is
replaced. When the system has calculated
that the external canister filter is near the
mileage interval, a REPLACE TRANSMISSION
OIL FILTER SOON message comes on. Replace
the external canister filter before the
indicator reaches 0%.
Failure to replace the transmission filter at
required intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will replace
the external canister filter and reset the
system. If the system is ever reset
accidentally, the filter should be replaced
according to the service intervals indicated
in the Service and Maintenance section until

Brake linings should be replaced as complete
axle sets.
Brake Squeal and Brake Dust
Some driving conditions or climates can
cause a brake squeal when the brakes are
first applied, clearing up following several
applies. This does not mean something is
wrong with the brakes.
Vehicles equipped with high performance
brake systems provide superior fade
resistance but will produce increased brake
squeal and brake dust on the wheels and
calipers as compared to standard brake
linings. This is normal.
To help reduce squeal, the brake pads are
treated with an anti-squeal paste that may
need to be reapplied periodically as part of
normal vehicle maintenance. The anti-squeal
paste will dissipate over time. Also, the use
of wheel cleaners or power washers directly
on the brake calipers may remove the
anti-squeal paste from the brake pads.
It may be necessary to reapply the
anti-squeal paste if it is removed during
cleaning.If brake squeal is excessive, the anti-squeal
paste should be reapplied. The anti-squeal
paste should always be reapplied whenever
the brake pads are removed or replaced. See
your dealer for service.
Brake Pedal Travel
See your dealer if the brake pedal does not
return to normal height, or if there is a
rapid increase in pedal travel. This could be
a sign that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts with
new, approved replacement parts. If this is
not done, the brakes may not work
properly. The braking performance can
change in many ways if the wrong brake
parts are installed or if parts are improperly
installed.
The Brake Fade Warning Assist system is
designed for use with the factory-installed
brake pads or GM-approved replacement
pads. If the brake pads on the vehicle need
to be replaced, use GM-approved brake pads.
If this is not done, the brake fade warning
system may not function properly.
High Performance Brake Lining Car Wash
and Extended Parking Care
If equipped with high performance brake
components, binding or clunking may be
noticeable after extended parking or in cold
weather when the brakes have been wet,
such as when driving in the rain or after a
car wash. The clunking is normal for brakes
with high performance brake linings and
does not affect the operation of the brakes.
When driving, normal braking will allow for
the brakes to feel smooth and the clunking
to go away. If the vehicle is washed before
overnight parking or long term storage,
drive it and apply the brakes several times
to thoroughly dry the brakes
Brake Rotor Wear (Z06/Z07/E-Ray with
J57 Carbon Ceramic Rotors)
Vehicles with the J57 brake option have
carbon ceramic brake rotors. The rotors
should be visually inspected whenever the
brake pads are replaced. Carbon ceramic
brake rotors also need to be weighed before
brake pads are replaced to confirm that the
rotor mass is greater than the wear-out
mass printed on the rotor. The rotor can be
reused if the weight of the rotor is above

.A fluid leak in the brake hydraulic system.
Have the brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid reservoir cap
and the area around the cap before
removing it.
Do not top off the brake fluid. Adding fluid
does not correct a leak. If fluid is added
when the linings are worn, there will be too
much fluid when new brake linings are
installed. Add or remove fluid, as necessary,
only when work is done on the brake
hydraulic system.
Caution
If too much brake fluid is added, the
brake fluid can spill and cause vehicle
damage, including damage to electrical
components and surfaces. Add brake fluid
only when work is done on the brake
hydraulic system.
When the brake fluid falls to a low level,
the brake warning light comes on. See Brake
System Warning Light 092. Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Replace brake fluid at the specified intervals
to prevent increased stopping distance. See
Maintenance Schedule
0316.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0320.
{Warning
The wrong or contaminated brake fluid
could result in damage to the brake
system. This could result in the loss of
braking leading to a possible injury.
Always use the proper GM approved
brake fluid.
Caution
If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Immediately wash off any
painted surface.
