Re: shifting problem
Changing the fluid and filter is always a good place to start if it hasnt been changed in a while. Also check the vacumn modulator and the line going to it. Pull the hose off at the trans, if theres evidence of fluid in the line, the modulator is bad, it helps control the shift points. Good luck.
