Bob,
Thanks for the reply. So far all I have removed is the solenoid. I think that
action of the solenoid at all means it's probably okay. I will have to order
new
o-rings for the solenoid, and a new ball for it. I have not taken enough parts
out to check the piston pump, but I will. I plan on rebuilding the circuit
(including lockout switch) later this week, as all the wiring is frayed.
I took some pictures of the solenoid removed, and one looking up into the
overdrive where the solenoid was. I do not see where any type of ball bearing
came out. Is it supposed to fall out when I withdraw the solenoid (by removing
the four bolts on the serial plate)?
Pics are at:
