Should see approx 13 ohms on all of the solenoids. Don't forget to check all the wiring and make sure your grounds are good.
BTW, the official way to check the fluid level is with the engine running and up to temp, Jeep on level ground, and transmission in P. If you don't know how old it is, change it. About 3.5-4L lives in the transmission itself, there's another 4L in the torque converter. Drain and fill it a few times. No need to drop the pan. Dex III/Merc only, don't use that ATF+4 junk
