Automatic Transaxle Fluid; When To Check And Change - Buick 2004 Century Owner's Manual

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 flame 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 your engine, which will damage it.
Always have the air cleaner/filter in place when you
are driving.

Automatic Transaxle Fluid

When to Check and Change

A good time to check the automatic transaxle fluid level
is when the engine oil is changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•
In hilly or mountainous terrain.
•
When doing frequent trailer towing.
•
Uses such as found in taxi, police or delivery
service.
If the vehicle is not used under any of these conditions,
change the fluid and filter at 100,000 miles
(166 000 km).
