if its not one thing its another - top problem now

Next I will disconnect the clamshell - though not sure what you mean by your last para. If I pry the ball end off will this have the effect you talk about?

Then if the transmission operates correctly am I looking at the black hydraulic rods being bad? Is there a check to confirm that?

Simon:

If the clamshell is jerking, you should also verify that the rails in which the black plastic sliders ride back and forth are well lubricated. It could be as simple as that.

The last paragraph of my previous post means that in certain positions of the top, there is a great deal of pressure applied by the black "hydraulic" pushrods to hold the clamshell shut. When the clamshell is down, it is very difficult to pry off the black pushrods off the steel balls on the V-lever. If you pry off the pushrod from the steel ball on the V-lever, the clamshell should move just as freely as your now- disconnected canvas portion of the top does.

The black pushrods only go bad when their ends sometimes get bent. If you can get one of those in a vise and apply enough pulling pressure, you can test whether the large spring inside is intact and functioning properly. It takes a LOT of force to pull it.

got it - thank you. The guides do look lubed but will check.

If I release the pushrods at the v bar so the xmsn does not drive anything will the mechanism go full travel from open to closed - ie the xmsn does not know there is no roof attached so it would just rotate as normal and stop on the limit switches. My thinking is if this is right then if both sides are ok and they rotate then the only thing left is the pushrods or the clamshell guides as you say.

will look first thing tomorrow

Yes, with all four pushrods disconnected, the V-levers should rotate fully and stop at each of the two limits if the microswitches inside the transmission are functioning properly.

The pushrods are off. They look ok, you say they are sprung - they both look solid - neither end moves. I have no access to a vice so must assume they are ok.

When I get a help (early here) for somebody to press the switch while I watch the XMSN I will test the travel.

Thanks
