Yes, it should fit.
Auto transmission fluid.
4F20E four speed automatic.
There is no transmission vacuum hose. That is a vent hose.
The Vehicle Speed Sensor on the 1996 Mercury Villager is located on the back of the transmission (as you look at the vehicle from the front) on top of the transmission with a pair of wires leading away from it... best to reach it from under the vehicle.

They are mostly identical, yes.
5W-30 is the preferred oil ( according to the 1996 Mercury Villager Owner Guide )
According to a website I was looking at : For a front wheel drive Mercury Villager , 3.0 liter V6 engine : 1995 ( 15 city / 22 highway ) 1996 ( 16 city / 21 highway ) Miles per U.S. gallon
No, it is not.
How do you remove the driver s seat from a1997 mercury villager
Yes, exactly the same.
I assume it is the same as the ( 1996 ) Mercury Villager : With engine oil filter change : ( 4.2 US. quarts of 5W-30 engine oil )
