Standing in FRONT of the car looking at the engine,Is the passing gear
cable on the left side of the throttle butterfly, or the right (drivers
side)

The smaller/thinner cable under the upper intake is unhooked. Is this
the TV cable, or the passing gear cable ? Thanks,

(1989 LTD Crown Vic, 302 5 liter)

That cable is the TV cable and controls the Throttle Valve pressure in the
transmission. Running with it disconnected will burn up the trans in very quick order
(as little as 5 miles). The cable is attached to the throttle lever via a plastic
bushing that deteriorates over time and falls off. Ford has a brass replacement for
about $5. DON'T drive the car until you replace the bushing, not even to the parts store.

Everything stated above is true. I just wanted to add that there is no
additional "passing gear cable." The TV cable is responsible for
everything. It's also much more serious than it was in the old days when
you had a "kick down rod" disconnected, because the internal transmission
pressure is entirely determined by the TV cable.

To add the "why".... these transmissions don't have a vacuum modulator to
sense engine load.... Instead, they use rpm and throttle angle (position
through a proper adjusted TV cable.... no, going to a satellite dish wont
help) to determine the appropriate line pressure.

Very well documented. Little plastic bushing, maybe $0.50 worth. Wears
out in a few years. 99% of driving population has near zero idea of
how tranny works/doesn't-work.

Five miles or so and they burn up a very expensive tranny.

I hereby nominate the 50 cent bushing as the "Supreme Fordmobile
Engineering/Manufacturing Boondoggle Of The 1980's".

Anybody gotta more worthy candidate?
