Vehicle Care 10-15
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 11‑8.
. 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.
Manual Transmission
Fluid
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 HUMMER
dealer 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 the
transmission. Too little fluid
could cause the transmission
to overheat. Be sure to get an
accurate reading if checking the
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.
3. Check that the lubricant level is
up to the bottom of the filler
plug hole.
