Placeholder in case someone else encounters the problem. The lid has a bolt on top that rotates and pushes the gasket out. Mine froze, and the gasket just came out as I applied pressure. If that happens to you, it's important to break the bolt on top loose rather than trying to force the gasket in.
I got a mechanic to help. He took the gaskets off, put blaster penetrating oil on the parts that froze, waited for a bit, put it back in the housing, and then used an extended socket with a 6mm and broke it loose. Then, he took the lid out, cleaned it, replaced the gaskets, put it in the filter (it only goes one way), put the filter and lid back in the housing, tightened to specifications, and we were done. Twenty bucks plus a healthy tip.

The instruction for removal and installation of the filter show the loosening of the socket head bolt. In most cases if the socket head bolt is tightened to tight. (there is a torque spec included with the filter removal /installation) The aluminum cover threads will start to Gall. This is aluminum with a stainless bolt. Over tightening it will damage the threads in the cover. In your case it sounds that the threads were still usable but close to being permanently damaged. I have seen many that did not loosen because of over tightening.
The filter should not be installed or set into the reverse gear. It should be installed over the o-ring on the cover and the cover and filter should be installed into the housing as an assembly. Pushed down to seat the large ring to seal the cover and then the socket head bolt tightened to the proper specification. 70 in-lbs or 5 to 8 Nm.

I am glad we were able to loosen it. Re. the filter, that's the way we put it in. I will probably order another cover for next time. Do you have a part number?

For my D4, my reverse gear is a Volvo HS63A. It looks like the Volvo part number for the cover assembly is 3582063 (https://www.volvopentashop.com/epc/...M-MG6-A/M-MG6-A_4400/M-MG6-A_4420/M-MG6-A_014
The cost isn’t trivial. If the price at Marine Parts Express is an indication of what Volvo will charge, it is over $300 (https://www.marinepartsexpress.com/cart/index.php?ID=+3582063&Go.x=8&Go.y=12&Go=Go).
The HS63A is made by ZR and is the same as the ZR 63. You might want to consider getting a ZF replacement cover instead of the Volvo for about half as much. Seaboard Marine in Seattle would be a good source. https://www.sbmar.com/product/zf-638085-atf-oil-filter-cover/. If you call them, they should be helpful in making sure you get the right ZF part.

Looks like mine is the same one. We'll order that one and have it ready for our next change.
