My 2002 Galant DE is having transmission problems. Going to replace the wires and sensors first to see if they are the problem, if not I was thinking about changing the transmission. I'm sure I can get the old one off, but when it comes to installing the new one, would it be best to just have a professional install it? I have plenty of tools, but if the tiny things matter with replacing it, I don't want to get involved with installing the new one myself :p any advice?
