I have a 92 Taurus wagon and the transmission slips. It will not move
from a standstill. Lucky I was parked on a hill and at 15mph the
transmission works fine. I read some posts and one in particular
cought my intrest.
snip> adjusted the TV linkage. It is a touchy adjustment though(millimeters matter,
for it adjusts tranny pressure).
Can someone explain this touchy adjustment or give me some reason why
the trany will not move when at a complete stop but works fine once
I'm going 15mph.
I was lucky to get the vehicle home as there were two stop signs that
gave me enough visual to go through them.
I don't *think* you have a Throttle Valve cable/linkage. I'm pretty sure
that the last year for the mechanically controlled transmission in the
Taurus was 1991, and that 1992 and newer have electronic transmission
controls. Incidentally, the early electronic transmissions were not very
reliable. If you have one of those, you have had better than average life
out of it.
Here's how you can tell if you have a TV cable or not. The TV cable runs
from the intake throttle butterfly down to the transmission. A TV cable
controls the internal pressure of the transmisssion. When you increase the
throttle position, it increases the transmission pressure; when you let off
the throttle it decreases internal pressure. This is used to control
upshifts and downshifts, and to keep the clutches engaged. The biggest
problem arises if the cable breaks or gets disconnected at either end. In
such a case, driving the car will quickly ruin the transmission. What
happens is that there is insufficent internal pressure to keep the clutches
engaged. They slip a lot and burn up in no time.
Look to see if you have a cable running between the intake and the trans,
and let me know. If you find one, check to make sure it's still properly
attached on both ends.
