2000 3.0L has a 4 speed automatic (4R44E).
The 5 speed version (5R44E) has basically the same internal parts but the electronic controls use 1st with overdrive to create an additional gear between the four speed's 1st and 2nd. This new gear is not used during most driving, only at or near WOT for a slight improvement in acceleration. For two otherwise identically equipped Rangers, fuel economy should be comparable between the 4 speed and the 5 speed autos.
