What owners should do
1. Confirm whether your vehicle received the factory remedy (dealer service history or VIN lookup at [NHTSA.gov/recalls](https://www.nhtsa.gov/recalls)). 2. Do not assume a high-mileage donor transmission was repaired before removal. 3. Compare **remanufactured** options that include updated components vs **used** units from unknown recall history.
Replacement options
When the recall affects transmission components, remanufactured transmissions are often the safer value choice because they are rebuilt with current parts — not pulled from a donor that may pre-date the factory fix.

Frequently asked questions
Does this recall mean every transmission on this platform is defective?
No. The recall applies to vehicles that may not have received the factory remedy. A used transmission from a high-mileage donor may never have been repaired under the campaign.
Is remanufactured safer than used when a recall is open?
Remanufactured assemblies are rebuilt to current specifications and are not dependent on an unknown donor repair history — a common consideration when an open powertrain recall affects the platform.
Should I remove my transmission before contacting support?
Document symptoms, save scan results, and contact support with installation details before removal so the issue can be reviewed accurately.
