# Service bulletin NCU\-2020060009

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- NHTSA id: 10177543
- Published by NHTSA: 2020\-07\-27

## NHTSA's summary

The software for the transmission control unit on the above model series vehicles transferred to you does not correspond to the current series production configuration. Because of this, the transmission may not shift beyond third gear when in automatic drive program D. Manual shift operation beyond third gear is still possible using the paddle shifters.
