1995 Mercury Villager Transmission sensor?

Transmission problem
1995 Mercury Villager Automatic

hi

my family now resides in Mexico City and they took their '95 Mercury Villager with them. They have an unusually hard time finding parts for the car.

The latest culprit is this cable. My dad says the mechanic told him is part of the tranny, a sensor of some sort.

Could someone help me with the name of this part?

Thanks!!
