Don't know if you solved your issue but here is the way to test. This was provided to me by a larjerr on the forum. My #3 read 163 ohms... I changed the solenoid and is well now. "Unhook the roundish black connector in the engine compartment near the tranny dipstick(7 wires). Coming from the transmission, the pin you wanna check with the ohmmeter (black lead to battery negative, red lead to pin) is the one with white wire with black stripe. Should read 11-15 ohms, if not inspect the wiring . I ordered solenoid 3, part # 5016121AA and believe this will solve my problem. The two pins next on the row, tannish with white stripe and bluish with white stripe, the other two solenoids, should also read 11-15 ohms"
