Automatic Transmission Fluid - Chevrolet 2009 HHR Owner's Manual

To inspect or replace the filter, do the following:
1. Remove the screws that hold the housing and
cover together and lift off the cover.
2. Inspect or replace the engine air cleaner/filter.
3. Reverse the steps to reinstall the system. Be sure
to reinstall the housing tightly.
CAUTION:
{
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can easily get
into the engine, which will damage it. Always have
the air cleaner/filter in place when you are driving.

Automatic 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 your vehicle to a dealer/retailer and
have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance on
page 6-4. Be sure to use the transmission fluid listed
in Recommended Fluids and Lubricants on page 6-14.
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 6-14.
