For Stop / Start purposes 8F Taransmission comes equipped with a Transmission Hydraulic Accumulator, an electronically controlled device that can store pressure while the engine is running, then during a stop/start engine restart can release that pressure into the line pressure hydraulic circuit, allowing the transmission to engage before the main pump is outputting pressure. This allows quick response on the engine restart because the transmission reengages before the engine starts. The Transmission Hydraulic Accumulator is controlled by an on/off solenoid, which is turned on to release the pressure stored in the accumulator.

The solenoid is controlled by “smart driver” chip – when the main micro sends out the commanded state the smart driver returns fault information (open, short to power, short to ground). The accumulator is also functionally monitored during stop/start engine restarts – if excessive clutch slip is detected the accumulator did not discharge, which could be due to the accumulator stuck open or closed.

If a Transmission Hydraulic Accumulator fault is present the stop / start system will be taken out of operation with the engine running (no more stop events while the fault is present). Circuit failures can recover during a drive cycle, but functional can only be detected when the accumulator is turned on during a stop/start engine restart - those faults will require a key cycle to recover.
