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.
