I dont remember the ohm spec but ohm all of them as I believe they should all be about the same. If one is way off it may be bad or of course if its an open circuit its a problem. Seems to me 15 to 30 ohms or somewhere in that area was what I used to get. If you plug in the solenoid pack on the car and then unhook the trans relay and trans controller you can ohm from the relay power wire that powers the solenoids to each solenoid at the trans controller plug. Course having the wire diagrahm will help. I have them around here somewhere but would have to dig them up. Ron
