Well, I fixed it last night. Only thing is, I aint sure what fixed it.
I bought a new pressure sender and replaced it. Thing is, when I was under there to change it, I saw alot of oil blow-by on the crossmember back to the transmission pan. It was coming from the seal at the oil filter. I decided to replace the sender anyway since my Pfinder has 108,000 miles on it.
Some of my google searches found people who thought the filter could be defective causing the high pressure. I went ahead and replaced the filter while I was there, so I dont know which fixed it.
