JR,
Right behind the drivers side front wheel you will see a transmission pan mounted sideways. Remove this pan and the lockup solenoid will be behind there. Easy to replace. Look at it real good, on your vehicle you just might be able to get that cover off without lowering the engine cradle.
Here is a pic of the lockup solenoid. Check with your local auto parts stores, they might carry them. I was wrong about the price of yours, my supplier LISTS them for $35 so you should find them for under $50.
