'95 Sable: "Trans Control Piston" & Lucas Trans Fix ?

Aug 11, 2003 2 Replies

Hello:



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 wheels.



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 ?



Much thanks, Bob


Hi, Thanks for help; appreciate it.

What might you suggest for my apparently cracked accumulator piston ?

Does the "whole" transmission have to be taken off and "re-built" ?

Thanks, Bob

Since it has to come out of the car and disassembled, yes. Be prepared to pony up $2000 or so (give or take a few hundred).
