Just bought a 1993 Nissan altima with 1322345 miles on it.car is in decent condition engine is strong. About 2 days ago while im driving it seems to slip out of gear, when I go to put it in park or any other gear I hear a grinding. Now the guy I bought it from has changed the left cv joint I looked it's brand new. Also there is a very slow transmission fluid leak lokks to be the in board side of that cvjoint. Car goes into gear sometimes but the same happens seems when I turn sometimes think it might be the drive axle cvjoint not engaging
