Pinpoint Test B : DTCS P0755, P0758, P0759, P0976, P0977: Notes
Refer to Transmission Controls - MPS6 for schematic and connector information.
Normal Operation and Fault Conditions
The PCM applies and releases the various clutches in the transmission by actuating the shift solenoids in the solenoid body. SSB is a Variable Force Solenoid (VFS).
