auto transmission TCC
 

Just did a check of all the auto’s solenoids resistance
and found a couple of interesting things.
Found the pressure control and 2/4 duty solenoids we
3.5 ohms , slightly over the maximum of spec 3.2 ohms.
Does this matter?
The one that was a bit out was somthing called a TCC solenoid.
tested at 14.7 ohms when it should have been 13.2ohms max.
Does this matter.
The rest were within spec.

Is it shifting ok? What was the need for testing?

Had an issue with the EP Fault came up and loss of all drive. Switched it of, restarted and all was fine for days.Has done this on a couple of occasions over
last month, always seems when car has been sitting cold .
Some days seems fine but other times gear changes are flaring a little between shifts but gets smoother the warmer the engine gets.
Fluid changed with my normal fluid a month ago.
I did find the main plug to the auto box was not fully locked together so not sure
if that may have caused issues.
The auto had a replacement reverse piston done at 70,000km , car has now done 230,000km
Some days changes are fine, other day changes are a little harsh.
Edit - think the TCC solenoid is also called the Lockup Solenoid
