- Type: Service bulletin
- NHTSA id: 10240490
- Published by NHTSA: 2023\-08\-05
- Manufacturer's number: SA\-041\-23

## NHTSA's summary

The 7G large platform utilizes a new 8\-speed automatic transmission. Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running \(or Ready\-On for PHEV\). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start. In the event that a vehicle cannot be started or achieve ready\-on, wheel dollies must be used to allow the vehicle to be rolled and moved NOTE: The following procedure is for moving vehicle around the service shop and not for towing purposes. Please reference the owner's manual for towing instructions.

Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running \(or “Ready\-On” for PHEV\). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start and can't move, usually due to a discharged \(dead\) battery. In the event that a vehicle cannot be started or achieve “ready\-on”, wheel dollies must be used to allow the vehicle to be rolled and moved.
