DTC P072A: Stuck in Neutral
General Description
The automatic transmission of this vehicle uses a dog type clutch. When the dog clutches A and F unsuccessfully engages when the shift position is selected to D position/mode, there is sometimes when it cannot shift to DRIVE position/mode (i.e. neutral condition).
