It does not take much fluid,
generally less than one pint (0.5 L).
Do not overfill.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered
by the vehicle’s warranty. Always
use the automatic transmission
fluid listed in Recommended
Fluids and Lubricants on
page 6-12.
After adding fluid, recheck the
fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
When the correct fluid level is
obtained, push the dipstick
back in all the way; then flip
the handle down to lock
the dipstick in place.

When to Check
A good time to check the manual
transmission fluid is when the
engine oil is changed. However,
the fluid in the manual transmission
does not require changing.
How to Check
Because this operation can be a
little difficult, you may choose
to have this done at your GM
dealer/retailer service department.
If doing it yourself, be sure to follow
all the instructions here, or there
could be a false reading.
Notice: Too much or too little
fluid can damage your
transmission. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission fluid.
To check the fluid:
1. Park the vehicle on a level
surface, then shut the engine off.
Let the vehicle sit until the
transmission case is cool enough
to touch.
2. Remove the filler plug.
