My wife's 97 Wagon began having trouble with the transmission (or so I thought), it would seem indecisive when holding speed at 25 and 35 mph. Giving it some more gas would force it to down shift rev up and clear out the problem.The problem would get worse with damp weather leading me to believe there was sensor trouble. I let it go hoping for more symptoms to occur, I caught a break when it began really bucking on a rainy day and finally threw a code. Turns out it was misfiring, new plugs and wires cleared the problem right up. The worsening in wet weather indicates that the insulation on the wires had broken down. Since I had convinced myself it was a transmission problem searching on this site led me nowhere. I have posted this to help someone who may have led themselves down the wrong thought path.
