Not matter how long I let the car warm up the first few miles I cannot shift that thing smooth to save my life. Always jerking me around and it makes me look like I cant drive stick. Very annoying. It goes away and becomes much less noticeable. But will still be hard to keep the shifts as smooth as I'd like them to be. Seems to be mostly from 1-2 and 2-3 shifts. The 3-4 and 4-5 are much easier to keep smooth. So what's the solution? New trans fluid? Rear differential fluid? New Clutch? All of these above?
