Engine start process:
- When the engine is restarted, the solenoid holding current is removed, which starts the unlocking process.
- The magnetic core is released and the keeper is moved towards the piston under spring pressure. The balls fall into the detent in the keeper, releasing the piston.
- The piston is moved under spring pressure, pushing out the volume of ATF. The one-way restrictor opens fully to allow unrestricted flow of ATF from the accumulator cylinder into the transmission housing. The process is completed between 300 and 350 ms.
- Once the engine is started, the ATF pump produces flow and pressure to provide seamless transmission shift element engagement as soon as the engine is started.
