Manual Transmission Fluid
When to Check Manual Transmission
Fluid
A good time to have your manual transmission
uid checked is when the engine oil is changed.
SeeAdditional Required Services (Gasoline
Engine) on page 621to nd out when to change
your transmission uid.
How to Check Manual Transmission
Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealership
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.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.
Then, follow these steps:
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, install the plug and be
sure it 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. Refer to the Maintenance
Schedule to determine what kind of uid to
use. SeeRecommended Fluids and Lubricants on
page 629.
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. Install the ller plug. Be sure the plug is fully
seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is lled with hydraulic clutch uid.
It is not necessary to regularly check clutch uid
unless you suspect there is a leak in the system.
Adding uid will not correct a leak.
A uid loss in this system could indicate a
problem. Have the system inspected and repaired.
When to Check and What to Use
The clutch master
cylinder reservoir is
located in the rear of the
engine compartment on
the driver’s side of the
vehicle. SeeEngine
Compartment Overview
on page 480for more
information on location.
Refer to the Maintenance Schedule to determine
how often you should check the uid level in
your clutch master cylinder reservoir and for the
proper uid. SeeOwner Checks and Services
on page 625andRecommended Fluids and
Lubricants on page 629.

performed at the intervals specied to help
ensure the safety, dependability, and emission
control performance of your vehicle. Your
GM Goodwrench
®dealer can assist you with
these checks and services.
Be sure any necessary repairs are completed at

to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 629.
At the First 100, 1,000 and 6,000
Miles (160, 1 600 and 10 000 km)

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your GM Goodwrench
®dealer if service is
