Car not 'shifting up'
Hi! I have an old 1996 Crown Victoria with about 130,000 miles on it. It still does pretty good for me, except that it is sometimes very sluggish just after being started. It will putt along at only about 30-some miles per hour for a while, and feels like it isn't shifting up as it should when I accelerate. Once it gets warmed up, it seems okay again. We did try adding transmission fluid, but that doesn't seem to have helped. Any other ideas?
