I have an 84 gn with an 87 2004r in it. While changing the pan gasket I noticed a pressure switch or solenoid on passenger side middle to rear of trans. It has a green wire going to it and it looks like a temperature switch from a third gen (kindof). I screwed it out and took it to every place here in town. Nobody can help me. The little brass conn where wire snaps to is broken. The people who seem to have them online dont have pics. It said 240 or 280-340 kpa on it. I should have wrote it down but didnt. What is it exactly and where can I purchase a new one?
