To remove the Vehicle Speed Sensor (VSS) the vehicle must be first lifted, and a drain pan should be placed below. Disconnect the electrical connector from sensor; meanwhile, remove the bolt. Using the twisting and pulling motion, remove out the vehicle speed sensor from the case and dispose of the O-ring seal. For installation, apply a new O-ring seal on the vehicle speed sensor and before reinserting the sensor into the transmission case, coat with clean transmission fluid. Tighten the bolt to 11 Nm (97 inch lbs) by installing it. Unplug the wiring harness electrical connector from the vehicle speed sensor, take out the drain pan, drop the vehicle, and top the transmission off to the right level with DEXRON (R) III transmission fluid.
