Hi mate I can't find any diagrams for you but you could to go to a Toyota dealers to order the parts and when you are there ask them to see the part on screen or in a parts manual then you will know which one and where it is. I would think to replace the solenoid you would drain the Oil, remove the transmission sump plate to get at the solenoids but I have never worked on a Toyota Auto box so I am not 100% here. What happens if you start off in L then shift manually does it work ok then? Anyway I have included a PDF file (you will need the free Adobe reader to open this file) which does explain what is going on with a Toyota autobox, not exactly your one but the basics are the same.

Regards Pete.
