The car has 34k miles on it, no leaks and seems to be in good condition. Drove fine on test drives, drove fine the first day I owned it, but now has some very strange transmission behavior. Shifts fine most of the time, but sometimes downshifts then upshifts for no apparent reason. This does not occur every time I drive the car, but appears to happening more often. It happens at any speed, throttle setting, etc. I have no check engine light or other warning lights coming on, and the gauges seem to work fine, no erratic readings from speedo, temp gauge, etc. The fluid level is correct and the fluid does not apppear to be burnt or discolored. Any light you can shed on this problem would be greatly appreciated. Thanks, Mike Mike My Toys: 99 Contour SE Sport V6 ATX 76 F150 Ranger XLT 460 V8 79 Bronco Custom 351M V8

The most likely cause is the range sensor on top of the tranny. jeff Adding to mercman's suggestion above, I wanted to ask you, "Does your O/D Light flash?". If not, check your battery cables and the ground that connects the transaxle case to the fender well. I had this same problem about 8 or so months ago, with no O/D light flashing, and come to find out it was a bad connection on the ground cable for the battery. If your O/D light is flashing, then I would start looking at that range sensor like mercman suggested. Welcome aboard!! Phillip Jackson `98 Mystique LS 262K+ and counting...

It looks like mercman was right on the money, bought a new range sensor from Ford for $28, hasn't acted up since I put it in. While I had everything apart, checked all ground connections, etc. all looked good. Thanks to all who replied.
