Gentlemen, I need some help deciding whether to buy a new solenoid block or a transmission wire harness.
I have a 2004 Exp. XLS, 4.0L, vin k, 4 wheel drive.
Recently the O/D light started to blink after a couple of miles of highway driving, with no noticeable difference in how the transmission acts.
I took the car to a shop and they said that the code stored was P1744, and that the solenoid block has to be replaced.
Today I removed the solenoid block and I measured the impedance of each solenoid. Unfortunatley I do not know what the values have to be, so I have no comparison. The eight solenoids are basically of three types:
Type 1: a single solenoid (measured impedance 9.8 ohms)
Type 2: three identical solenoids (measured imp 4.6 ohms for everyone of them; therefore I concluded they are ok)
Type 3: four identical solenoids (measured impedance 22.6, 22.8, 23.0 and 23.1 ohms; I believe they also must be ok)
Since there is only one type 1 solenoid, I am thinking that there is a chance that this one might be out of specified impedance range.
I checked the continuity between each solenoid and the central pins and they seem to be ok (instead of 0.0 ohms I got 0.1 - 0.2 ohms, but I think that's ok)
The other thing I am thinking of is that the control cable might have a broken wire.
If somebody knows the impedance values for these solenoids I appreciate if he could post them here.
I plan to apply 12v to each solenoid to see if it reacts to the voltage (using a small 12v bulb in series so I will not burn a good solenoid).
If anybody has some suggestions regarding this issue, please post!
Thanks in advance
Dorin
