SA-041-232023-08-05. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING; PARKING BRAKE. The 7G large platform utilizes a new 8-speed automatic transmission.

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.
