Circuit/System Testing

NOTE:

You must perform the Circuit/System Verification first.

1. Verify the transmission line pressures are within the specified range. Refer to Line Pressure Check , and Solenoid Valve Pressure .
   • If the pressures are not within range 

     Refer to Fluid Pressure High or Low .

   • If the pressures are within range 
2. Ignition OFF, remove the Q8 Control Solenoid Valve Assembly.
3. Verify the pressure changes for all solenoids when performing the solenoid test. Refer to Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test .
   • If the pressure does not change 

     Replace the Q8 Control Solenoid Valve Assembly.

   • If the pressure changes 
4. Verify the conditions listed below do not exist. Repair or replace as necessary.
