New Warranty Registration

ACDelco(R) has implemented a Powertrain Warranty Registration process for ACDelco(R) remanufactured engines and transmissions. This registration process will provide better tracking of our vehicle owner base and improved customer warranty support.

The Powertrain Warranty Registration Form, WA-39A, is now included with all ACDelco(R) engines and transmissions being shipped. This form is triplicate on carbonless paper. One copy is for the vehicle owner, a second is for the installing facility and the third copy is for the ACDelco(R) Powertrain Registration Center. The Registration Center copy is a pre-addressed, postage paid mailer.

The installation facility will be responsible for completion and proper handling of the Powertrain Warranty Registration Form. The installation facility should present the customer the completed warranty registration form, as well as a copy of the repair order, in a specially provided vinyl envelope (WA-39ENV). Finally, the ACDelco(R) copy of the Powertrain Registration Form should be mailed promptly to the Powertrain Registration Center for processing. Upon receipt ACDelco(R) will confirm the warranty registration by mailing the consumer a thank you letter.

Additional quantities of the ACDelco(R) Powertrain Warranty Registration Form, WA-39A, are available through Vispac by calling 1-734-266-5018.
