Subject:
Revised Maintenance and Lubrication for Automatic Transmission Service Interval/Correct Filter to Replace
Models:
2001-2006 Chevrolet Silverado
2001-2006 GMC Sierra
with Allison(R) Automatic Transmission
This bulletin is being issued to revise the first automatic transmission service interval and specify what filter to replace in the Maintenance and
Lubrication sub-section of the Service Manual. Please replace the current information in the Service Manual with the following information.
The following information has been updated within SI for 2001-2004. If you are using a paper version of this Service Manual, please make a reference to
this bulletin on the affected page. The 2005 and 2006 Owner's Manuals have also been corrected.
The first automatic transmission service interval is at the first maintenance service performed on the vehicle. At that time, change the external spin-on
filter only.
At every 83,000 km (50,000 miles) (normal service) or every 41,500 km (25,000 miles) (severe service), change the external spin-on filter and fluid. The
sump filter is to be changed only during an overhaul.
