I just changed my clutch on my car, but im having problems getting the transmission to line up. The clutch is aligned perfectly, but I'm not sure how to get the engine and trans to line up perfect so I can get the splines to slide in. Just wondering if anyone has advice for putting the trans back on

 

You might have to turn the input shaft on the trans. If you search there are answers you can find immediately. I've done plenty of transmission installs most of the time you just have to beast it or call a friend.
