pics of the newer gearbox.... all the electronic seems to be ending on the valve body ..

1) should I replace the solenoids or the complete valve body from the previous gear . (or stay away from this realm)

in the attached pictures below you can see that there are 6 solenoid .. do they work like 1 for each of the Drive gears and one for R .. or is it a combination of these solenoids ?

btw thank you for the quick replays guys
