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.

You can see the servo cover from under the car. Three screws hold it on. Takes some maneuvering to get everything out. You may need to pry the trans on the mounts a slight bit to clear the sway bar.

Thanks, Guys. Real Dumb question: Is this housing full of AT fluid? Need to drain first?

I drained mine and still lost a quart. The lines going to it still have fluid in them. I used a vacuum fluid remover so I could re-use the fluid.

Think i'll head to Pick & Pull this week for a dry run and photo an intact servo so i know what it's supposed to look like. Thanks.

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.
