Important:
• This procedure tests On/Off type solenoid valves. • Visually inspect the physical condition of the solenoid before testing.
Inspect the O-rings before and after the test to be sure that they are not
cut or damaged.
Important: The supplied solenoid testing harness will not power the 4L60-E TCC On/Off solenoid. To energize this solenoid, apply battery, 12 V, positive and negative (-) to the TCC On/Off solenoid wiring harness using connector test adapter kit J 35616 . Use terminal E, Red, Power, and terminal T, Black, Ground. Refer to the Automatic Transmission Inline Harness Connector End View .
Important: Do not use air pressure in excess of 827.4 kPa (120 psi). Excessive pressure will not allow the solenoid ball check valve to seat properly. Recommended air pressure is 344.75 kPa (50 psi).
Important:
• All solenoids need to be energized to seal. • A small amount of air leakage is normal +/- 21 kPa (+/-
3 psi).
Important: Inspect the O-rings after the test to be sure that they are not cut or damaged.
