I just don't really care anymore and I'm probably going to end up selling the car. I noticed now that I have another leak underneath? I have a 2008 saturn sky redline with the GM LNP upgrade and I been having a blast driving it! I raced my Sky against the Cobra not too long ago and just ate it!
Yeah, you got F****D good man. Your mechanic is a scum bag. He also put the wrong weight fluid in the diff. He probably put silicone gasket material on, then closed it right up without letting it dry, rookie (coming from a 23 year old driveway mechanic haha), or he just doesn't give a F because he wants you to bring it back so you can pay through the nose again. I would visit his shop with a buddy and see whats up. DONT EVER GO BACK TO THAT DOUCHE.
