Thanks, Don, for the solenoid info. A glimmer of hope. Can the servo mechanism be viewed from underneath with the car on a lift or does the axod need to be removed?
Yes,I already inspected mine to see if it was the cause. The cover just barely clears the subframe, but it can be done. Get a new gasket before you take it off. Also, clean the area around and above it so no dirt gets inside the housing.
Stopped at the yard yesterday and pulled the servo cover (Tuna can) off a 1990 & got the c clamp (quarter sized) off with a screwdriver. Have i got the right thing? Any tricks to remounting? Seems like I'll need to lever that piston back into the housing. Will check on my car today, I hope.
Pulled the servo cover on my own car today. Jack stands. 3 qts fluid. Tipped the cover up, rather than down to avoid the frame. Alas, no joy, C clamp is intact. Lots of seepage after trying to button it up, out of light, will have to return to it. Thanks for all the input. At least I can rule this out.
