"Try testing the shift solenoids, it can be done with an ohm meter, heres how:NO. 1, NO. 2, NO. 3 & NO. 4 SOLENOIDS 1. To check solenoid seals, remove suspect solenoid. Connect battery voltage to solenoid. Apply 71 psi (5 kg/cm 2 ) to solenoid with battery voltage connected. 2. With battery voltage applied, air should pass through solenoid. Disconnect voltage to solenoid. Ensure air does not pass through solenoid. Replace solenoid if defective. 3. Using ohmmeter, measure resistance between case and solenoid connector terminal. Resistance should be 11-15 ohms. Replace solenoid as necessary.
SLN, SLT & SLU SOLENOID Raise and support vehicle. Remove transmission oil pan. Remove appropriate solenoid. See Fig. 1 . To check solenoid operation, connect positive battery voltage to solenoid terminal No. 1. Ensure an 8-10-watt bulb is placed in-line of positive lead. See Fig. 12 . Connect negative lead to terminal No. 2 and monitor valve's movement. Replace as necessary.
Can anyone tell me if they tested this? I dismantled two A560E transmissions and in both of them shift sol #4 does not have a spring to close the solenoid. This with no power connected it still allows flow.
Is this a fault? Or is the post Incorrect?
Thanks in advance
