2010 CHEVROLET SUBURBAN automatic transmission fluid

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. SeeRecommended
Fluids and Lubricants on page 7‑12.
Using a funnel, add fluid down the transmission dipstick
tube only after checking the transmission fluid while it is
hot. A cold check is used only as a reference. If the fluid
level is low, add only enough of the proper fluid to bring
the level up to the HOT area for a hot check. It does not
take much fluid, generally less than 0.5 Liter (1 Pint). 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 7‑12.
.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 and Change Automatic
Transmission Fluid
It is usually not necessary to check the transmission
fluid level. The only reason for fluid loss is a
transmission leak or overheating the transmission.
If you suspect a small leak, then use the following
checking procedures to check the fluid level. However,
if there is a large leak, then it may be necessary to have
the vehicle towed to a dealer service department and
have it repaired before driving the vehicle further.
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 7‑12.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance
on page 7‑3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricantson
page 7‑12.

How to Check Automatic Transmission
Fluid
Notice:Too much or too little fluid can damage
the transmission. Too much can mean that some of
the fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Too little
fluid could cause the transmission to overheat.
Be sure to get an accurate reading if checking the
transmission fluid.
Before checking the fluid level, prepare the vehicle as
follows:
1. Start the engine and park the vehicle on a level surface. Keep the engine running.
2. Apply the parking brake and place the shift lever in P (Park). 3. With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, move the shift
lever back to P (Park).
4. Allow the engine to idle (500 –800 rpm) for at least
one minute. Slowly release the brake pedal.
5. Keep the engine running and press the Trip/Fuel button or trip odometer reset stem until TRANS
TEMP (Transmission Temperature) displays on the
Driver Information Center (DIC).
6. Using the TRANS TEMP reading, determine and perform the appropriate check procedure. If the
TRANS TEMP reading is not within the required
temperature ranges, allow the vehicle to cool,
or operate the vehicle until the appropriate
transmission fluid temperature is reached.

.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield, Backglass, and Wiper Blades
on
page 6‑113. Worn or damaged wiper blade
replacement. See Windshield Wiper Blade
Replacement on page 6‑61.
.Body hinges and latches, key lock cylinders,
folding seat hardware, and liftgate hinges,
linkage, and handle pivot points lubrication.
See Recommended Fluids and Lubricants
on
page 7‑12. More frequent lubrication may be
required when vehicle is exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑101.
.Automatic transmission fluid level check
and adding fluid, if needed. See Automatic
Transmission Fluid (4-Speed Transmission)

.Four‐wheel drive only: Transfer case fluid change
(normal service). Check vent hose at transfer case
for kinks and proper installation. Check to be sure
vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washer
is used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water
can overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.
