The first one is over drive and the second is drive. It is best to just use overdrive when on the parkway and drive on slower back roads when there is hills and stop and go traffic. Overdrive is a higher gear.

The AXOD-E was renamed AX4S in 1993. In addition to the name change,
improvements in the lubrication of the gearset and capacity upgrades
were made. A centrifugal piston assembly was implemented in the
intermediate clutch position to improve 1st-2nd and 2nd-1st shift
quality and an increase in the clutch's durability was made on some
models. High energy friction materials were also introduced. A new twin
piston torque converter clutch (TCC) was introduced with the AX4S and
the AX4N on some models. The transaxle pan on this model will sometimes
read "AXOD Metric" since it's based on the AXOD transaxle. The data
plate code for this transmission is "L."
The Ford AX4S automatic transmission
is a four-speed electronic overdrive transmission used in 1995 to 2000
Ford Windstar minivan. The transmission is also used in 1991 to 2003 Ford Taurus
and Mercury Sable, and 1993 to 1995 Ford Taurus SHO models. The AX4S is
a second-generation version of the AXOD and AXOD-E transmissions used
in 1986 to 1991 Ford Taurus.
Overdrive is a lock up within the transmission. The other "gears" are fluid and belt driven. So, could be that the sensor that allows the overdrive to "lock" is dirty/faulty. A transmission shop should be able to tell you in a heart beat.
