  Q: How to service and repair the Vehicle Speed Sensor on a 4R100 Automatic Transmission on Ford F-150 Heritage?

  A: The service and repair procedure of Transmission Speed Sensor in a 4R100 Automatic Transmission starts with hoisting the vehicle in NEUTRAL position. Place an elevated transmission jack on the transmission after loosening transmission insulator-to-crossmember support nuts but leaving them securely fastened. Start by removing the crossmember bolts and then the two bolts which secure the heat shield to the transmission support crossmember to detach the crossmember. To access the sensors you need to lower the rear of the transmission then unplug the corresponding electric cable of the damaged sensor. To avoid contamination while working on the Turbine Shaft Speed (TSS) sensor, start by removing its bolt then uninstall the sensor. You should remove the Output Shaft Speed (OSS) sensor when needed by taking out its bolt. The Heated Oxygen Sensor connector should be put to the side while working on this step. The installation process should begin with O-ring lubrication followed by reinstalling the OSS and securing it with its bolt. Succeeding installation of the TSS device after HO2S connector repositioning, utilize lubrication on its O-ring and mount the TSS using its bolt. Expand the electrical connector of the affected sensor before reinstalling the crossmember to the transmission mount by using one nut for support while lifting the transmission to match crossmember bolt positions. Fasten the sensors and their bolts while tightening all installed nuts solidly. For the last step reinstall each of the two exhaust heat shield-to-crossmember bolts along with removing the high-lift transmission jack before lowering the vehicle.
