Pinpoint Test A: Transmission Control Solenoids

  1. Refer to TRANSMISSION CONTROLS - 8F35 for schematic and connector information.

    Normal Operation and Fault Conditions 

    The 8F35/8F40 utilizes 6 shift solenoids that are CIDAS (A, B, C, D, E, F). Power to the transmission shift solenoids is split into two power sources, transmission solenoid power control 1 TSPC1 and TSPC2. TSCP1 powers the shift solenoids B, D, E, and F. TSPC1 also provides power to TCC and LPC. TSPC2 provides power to shift solenoids A and C. CIDAS are mechanical in nature meaning no transmission fluid passes through the solenoid. CIDAS use an armature pin assembly that moves a control valve in the main control valve body to control and apply hydraulic fluid pressure. Each clutch (A, B, C, SOWC, E, F) has a corresponding shift solenoid (A, B, C, D, E, F) that is directly proportional. In directly proportional solenoids, zero current equals zero pressure in the control circuit and maximum current equals maximum pressure.
