2006 Saab 9-2X F4-2.5LSECTION Memory Box
MEMORY BOX
The memory box is mounted on the control valve and stores hydraulic correction values and learned values for the initial shifting pressures for each solenoid, based on its hydraulic characteristics at the time delivered from the factory. The TCM acquires data from this memory box and performs correction based on these data to control each solenoid. This ensures high quality shifting from the time the vehicle was delivered from the factory.
