I was just watching "Ratches And Wrenches" where he had a truck which would not shift. He did a transmission fluid and filter change and then removed the solenoid and replaced with a new one. But at one point showed how the solenoid had its own little grills, like a filter, and how they were blocked up with metal bits. He said he could probably clean it but would not risk it as he had the new part.
This got me thinking why in general do we not include this solenoid cleaning when we have the pan dropped and fluid changed?
It appears it would only take a minute or two, and worse case, just require a couple of new o-rings.
Is there some type of inherit risk of future failure if you remove and clean the solenoid?
Any other reason why this would not be recommended?
Seems silly to clean the fluid, change the filter but leave the solenoid clogged a bit so the pressure sensor cannot get correct data.
