Have a '95 mercury sable with about 80,000 miles on it.
Have a bit of a transmission problem, I think.
Occasionally, when in DRIVE, from starting out, or already in motion,
pressing on the accelerator does nothing.
Engine runs fine, but apparently disconnected from transmission and/or drive
Has been diognosed as a broken (or stuck ?) "control piston" in the
transmission, and that
I should try adding Lucas Transmission Fix fluid to the transmission oil.
Also have been told that Ford changed this "control piston" from steel to
Aluminum that year to save a few pennies, and hence the problems.
My question are;
a. what is this control piston ?
-does this sound like the likely cause ?
b. worth trying this Lucas product. ?
c. worth trying anything else ?
