DIY or shop?
Dealer or transmission shop. Ask about Nissan bulletin NTB18-077b and your CVT warranty.
Before you replace parts
- Read all stored codes. The Nissan bulletin does not apply if certain other CVT codes are stored.
- Check your VIN for Nissan bulletins and CVT warranty extensions.
- Have the dealer follow the bulletin repair chart.
- Ask whether the TCM needs reprogramming after the repair.
Safety / mechanic note
Verify with a mechanic. A CVT that loses power can leave you unable to keep up with traffic. A code points to a circuit or system, not always a specific part.
