Information

The factory-covered maintenance replacement of the external canister transmission filter
for the Chevrolet Corvette has its own warranty coverage, separate from the standard
Chevrolet First Maintenance Visit, starting with the 2024 model year. This warranty coverage is good for three years after new vehicle purchase.
The purpose is to replace the canister filter when the customer is notified to replace it in
the Driver Information Center at 7,500 miles (+/- 500 miles). The filter life percentage
shown to the customer is a simple calculation where 0% is at 7,500 on the odometer. The
transmission is not fully broken in until 7,500 miles, and the debris from the break-in process collected in the filter must be removed at that time. Replacing it early or late is not
beneficial to the transmission.
After the first factory covered external canister filter maintenance, all further maintenance,
as required by the owner’s manual, is the financial responsibility of the customer. See the
Corvette owner’s manual for the required maintenance schedule.
For Corvettes being considered for Certified Pre-Owned, ensure the external canister
transmission filter maintenance has been properly performed prior to sale.

Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict
between the procedures set forth in this bulletin
and the laws that apply to your dealership, you
must follow those applicable laws.

Warranty Transaction Information
The transmission filter should be changed at 7,500
miles (+/- 500) per the owner’s manual maintenance
schedule. The filter may be changed if the message in
the Driver’s Information Center says “Replace Transmission Filter Soon.” Claims may be rejected if this
criteria is not met.

Q&A
Q: Can I submit warranty for the external canister
transmission filter when the car arrives for its first
engine oil change?

Copyright 2024 General Motors. All Rights Reserved.

A: Yes, only if the odometer has at least 7,000 miles. If
the odometer does not meet this criteria, invite the
customer back when the message to change the filter
displays on their Driver Information Center.

Q: The customer wants the filter replaced early, can I
use this warranty coverage to pay for the replacement?
A: No, the odometer must have at least 7,000 miles to
use the factory covered maintenance. If the customer
wants the filter replaced prior to the GM recommended
schedule of 7,500 (+/- 500 miles), it is at their expense.

Q: If the transmission was replaced under warranty
under 7,500 miles, when should the factory covered
maintenance filter be applied?
A: The customer is then eligible for a factory covered
filter 7,500 miles after the new transmission was
installed for proper break-in. There is no upper limit to
the odometer for the factory maintenance coverage.

Q: The vehicle is very high mileage and may not have
had its external canister filter replaced during its
lifetime, what should I do?
A: Refer to the first Caution statement in SI Document
ID 5384826 regarding overdue filter replacement. Split
the cost of the service with the vehicle owner due to
the lack of proper maintenance. Only one filter is
allowed under factory covered maintenance.

Q: The customer’s Corvette is rarely driven. What
happens if the odometer is less than 7,000 miles after
three years?

A: The external canister transmission filter maintenance then becomes the financial responsibility of the
customer to replace it at the recommended schedule in
the future.

Q: Why was the Chevrolet First Maintenance Visit
allowance lowered?
A: The factory covered maintenance was split into two
allowed line items so that the external canister transmission filter could be covered at the proper odometer
for the product needs. The new allowance is for the oil
and oil filter change and fluid top off only, and no
longer includes the transmission filter change.

Q. I claimed labor operation 0600213 for the First
Maintenance Visit prior to April 25th, but the customer
did not get their transmission filter changed. Can I
submit a claim for labor operation 0603323 (0611813 in
Canada) when the customer gets their transmission
filter changed?
A. If the dealer submitted for the full allowance at the
time that allowance included the transmission filter
change ($343, $339 based on engine RPO), the dealer
is NOT eligible to submit a separate claim for the transmission filter change. As the dealer was paid for
replacing the filter at that time but it was not done, the
dealer is responsible for providing that service to the
customer at no charge.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
