It's about a 722.9 transmission from a 2007 E550:

Does anyone knows the correct resistance readings for the solenoids?
My WIS ASRA has nothing about valve body, I've looked online and i found just one YouTube video .... , but this guy's measurement values are 5 Ohm.
All my solenoids measure around 17 Ohm, but one that measure 10 Ohm.
Does it mean that is a bad solenoid?
What's the correct measurement to begin with?

Thank you.

I think that the you tube data is very unreliable in the fact that you can measure each valve resistance and compare on a macro sense, but you are correct there are no solenoid design range values in WIS------all that electrical data is built into Xentry and is seamless when testing the control unit---the solenoid is either within or out of design, ICGAS what those values are---i simply change the solenoid(s) that Xentry indicates is out of spec(faulty)(assuming solenoid pulled and there is no metal trash on the screen).

However if you want to assume that all solenoids have the same design parameters then I guess you could say 7 7 7 3 7 the forth solenoid is not the same therefore faulty.-----hopefully this is not a customer car!!

Never mind, my multi-meter wasn't that good, so i bought a new one that reads correctly 5 Ohm.
Case closed.
Thanks.
