Hi, thank you for translating and answering.
responding to your questions.
i havent replace any selenoid, and well, in the aplicattion chart, the shift selenoid number 2 its common for P R N, 1 and 2 so maybe, when it fails in P,N or 2 its not evident because in P and N the van isnt moving, and the 2 gear it actually its engaged by other solenoid. i will try to check it out its impedance in hot to se what happens.
for the turbine, or torque converter, i haven‘t replace it because it was very expensive, and also it wasnt new, but i wash it with a degreaser solvent, then left it to dry and then put a litle amount of mercon V to remove the rest of solvent. well, it maybe result damaged because of the metal pieces, but i want to discard first the external pieces before raise down the tranny again.
and the last,the sensor it was exactly the OSS output speed sensor, but i havent remembered. the scanner indicate that sensor, but when unpluged it, the van makes the same problem.
other thing that i noted is that my windstar, especifically the ax4s tranny, doesnt have the common VSS sensor, instead of that it has a metal cover with a ford part number. also doesnt have a conector, but well, i have read that the vss whas replaced in the ax4s for the hall type oss, also when i unpluged the oss, the velocimeter operates normaly.
the person in the part suplier place told me that because the vss was a common problem, now the signal comes from the abs sensor on the driver side frontal wheel, im not sure of that.
well now at least i have an idea of what to check. thanks.
