1) measured resistance between center pin, and it's 36ohms for both LU and OD.
2) feed 12V to center pin, measured LU and OD side to ground, they are both 12V.

So that seems to indicated that both solenoids are ok?
Did a google search and it looks like solenoids are basically a coil winding and should be a DC short.

So unless the other side, magnetic plunger in the solenoid is bad, I've got bigger issues.



Did you try to see if you had OD pressure? Report back your findings.

If the solenoid is truly good, first thing to look for is a stuck OD control valve, which lies underneath that solenoid.
