I'm having transmission shift problems also. Sometimes you push on the accelerator and it doesn't take right off, it hesitates. I looked up the 1S7Z-7M101-KA (Turbine Speed Sensor) - $15 at FordPartsOnline.com . It shows it's for a Ford Escape. I have a 96 Contour, 4 cylinder Zetec with ATX. I also read about a "shift selector Sensor". Could this be the problem ?? What about that TSS ?? Is this on my Contour ??
