ImportZ

I'm disabled, had brain surgery & paralyzed on my face, arm, chest, side & have weakness all on the right side of my body. That being said, that's why I have to drive a auto trans. A few years ago I bought a '08 350z from a dealership & I purchased an extended warranty. About 4 months later my gallery gaskets blew so I took it to the Nissan dealership to get fixed because I can't physically do it myself. I only had to pay $99.99 & they even replaced my control arms because they were ****ed too. When I start it up the max oil pressure reads 100 then it drops slowly. I have to drive it about 8 miles before it warms up to where it stays about 65 going about 60mph. Every since they replaced the gallery gaskets when I put it in drive my transmission lags in the first gear. It's like it's low on Transmission fluid but it's not. It's full, clear, & looks good. As soon as it's warmed up it drives fine. Any clue as what it may be? Any help would be appreciated. Thanks
