Auto Trans. Shifts real hard into 2nd gear and hard shift into Rev.

There is a return spring that is supposed to be on the transmission kickdown linkage that pulls it up against the carburetor peg. If this spring is broken or has come loose, this will cause the problem you are having. Look at the carburetor where the throttle linkage hooks up. You will have the carburetor return spring and there is supposed to be a kickdown return spring as well. Check to see that the kickdown linkage is all the way toward the FRONT of the car. It it is not, this could be your problem. I don't have anything with an automatic, or I would post you a picture. This would be the first thing I would check because it is a common failure and it is also a CHEAP place to start.
