The solenoid is only $40.00.. I think there's 2 of them, though.. It could also be the valve body, but I think it's the solenoid. I'll have to look into it more. If anyone knows of a writeup on it, or a good source to find repair info on it I'd appreciate it. I have a friend that's a mechanic at a Toyota dealership, and he said I can have full access to a bay in the garage on any Saturday for nothing... I should be able to get it done myself if I can find some info on how to do it!
