Hello! This solenoid is easy to get to with the pan off. And there are two solenoids that are identicle, the 1-2 and the 2-3 shift solenoids. It is usually advisable to do them both (as they are inexpensive and right next to each other.

 

With the pan removed., towards the back of the transmisison, you will see two square solenoids. Be careful removing these, as the 1-2 solenoid will be spring loaded. All you have to do is remove the retaining clip and pop the solenoid out of its bore.

Thank you. It's been several years since I have worked on an auto trans. Much less the new type overdrives. Thanks Again... Wes

No problem. The pan is a very tight squeeze between the trans and the exhaust, you may want to unbolt the exhaust from the engine to give yourself enough room to get the pan out without damaging the solenoids.
