Turn the steering wheel to the left, you will see the TSS, it has a latched plug. When unlatching the plug, it is easy to break the latch. 1S7Z-7M101-KA (Turbine Speed Sensor) or
XS7P-7M101-KT (one of those numbers is the latest, not sure which), cost about 30 bucks at Ford dealer, maybe less at
www.teamfordparts.com.Take it back to whoever installed the trans, so you won't pay for another.
