cstamm81, I questioned the hose(s) earlier but still have some doubt, esp if you've fully inspected them. (auto PS experience..) If either had ballooned/blocked there should be some pressure in one direction or the other(?) but if your cylinder moves freely unloaded I doubt it would be too high without being connected (weighted?) or at the end of stroke. It actuates by flow, of course, but some resistance may(?) help you interpret the tests.
Is there any reason S-box pressure output wouldn't be the same with the engine running or not, since the cylinder would be doing the same work either way to turn the wheels??? Whether the box is working would then only be obvious by effort/feedback at the wheel. Either you're getting 'boost' or not. If we can be sure the adapter plate is supplying adequate flow/pressure it would seem to point to the box as the problem. (Oh man, .. do I hope not ...)
I'll have to reread whether this issue just popped up or the T-M came this way. Could moisture/rust have stuck something delicate inside the box's control valving while stored/parked and stiffening/locking-up something? I had water collecting in my column without a center-button on the s-wheel. (doh!) Call me lucky that it hadn't gone inside & froze.
I'm hoping I can help out here without being a pest about it, but IMO us T-M guys could use some team work to get a handle on our steering issues. btw: I hope TerramitConnecticut is tuning in by now. Not sure he's up & running yet ...
