# Service campaign NCU \- 2026060005

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's summary

Issue The transmission control unit \(VGS\) in the automatic transmission does not comply with our currently valid specifications in the vehicles of the above\-mentioned model series delivered to you. It is possible that the polarities of the magnets in the transmission control unit \(VGS\) have been swapped. This could in turn result in shift quality issues and gear lockouts. Remedy MBUSA will conduct a service campaign. We therefore request that you replace the electrohydraulic controller unit \(EHS\) of the automatic transmission in the affected vehicles. Please refer to the attached work description for details on the operations required.
