Well Wisdom,

I have a 1994 Taurus wagon, When I shift my automatic floor shifter
through the ranges it links to a cable and in the engine compartment on
the top side of the auto transmission it links to a manual link switch.
This basically tells your transmission what gear you have moved your
shift lever too. This switch can go bad and tell the tranny the wrong
information. But the first thing I would do would be to disconnect the
battery for 10 minutes or so. This will start the computer that
controls the engine and the tranny to relearn and start over from the
factory settings. These computers to learn as time goes on and it's
logic can get messed up; so start here first before you replace any
parts. Check and if you have not done so for a while change the tranny
fuild and filter. A flush with a filter change would be the best but
that will cost a couple of bucks more. Check the fuild with the engine
running and at normal temps about 15 miles of useage, if this is not
done you will get a low of incorrect fluid level reading. You don't
want to overfill this unit, it will foam and cuase problems. Dexron III
is probably the correct fluid but be sure buy looking at your owners
manual if you have one. It probably say Dexron II but that is what was
made at the time 3 will be ok. Also on that manual linkage switch I
talked about, I would disconnect it and see if any contacts are
curroded; clean if nessasary. Good places to start with...
