First go get the mani and then locate the tps sensor which is in the back of the tb. The map sensor is located on the top of the tb. Make sure you look inside the plug and make sure there is nothing rusted or whatever. If that seems to be good then more than likely the sensor is messed up. The tranny seems like it's shot or low on ATF. I would check the oil level on the trans and see where it's at. If it's good go buy some lucas and see how far that takes you.
