Automatic Transmission Fluid - GMC 2005 Savana Van 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 Transmission Fluid

When to Check and Change
A good time to check your automatic transmission 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's GVWR is over
8,600 lbs (3 901 kg) or 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 your vehicle's GVWR is not over 8,600 lbs (3 901 kg)
and you do not use your vehicle under any of these
conditions, change the fluid and filter every
100,000 miles (166 000 km).
