Before you dive into replacing the solenoid you need to ohm check it to determine if it is even bad. The best place to start is right at the pcm connector and use an ohm meter to check the resistance between the two wires for the pcs that go to the trans. There are ohm specs for the solenoids on our website for reference. You will need to get a pcm connector pinout picture and schematic to find the correct wires but this is a must-do step. You should also check each wire to ground and also measure each wire from the pcm connector to the transmission connector to make sure there is not a broken wire or one rubbed through and shorted to ground. A common wear area is just under the air box near the AC accumulator and lines where the harness lays on it. After the external wiring has been verified good/bad and if ok then you should do an ohm check right at the trans connector itself to check the solenoid resistance and if found bad right at the trans then it could be a bad internal transmission wire harness or the solenoid and that would require dropping the transmission down to remove the side cover for repair.
