1. Wrong sub forum
2. What has seafoam to do with transmission?
3. With the code you will likely have a failing shift solenoid. open up the pan and disconnect the solenoids, with an ohmmeter see if the resistance changes.
4. there is a similar thread to this on the 2gs subforum, with a detailed guide on this.
