Stuck in 1st gear

IMO
the trans overshifted into whatever gear it' stuck in, allowing the struts to pop out from under the slider. When this happens, the brass ring is allowed to rotate. When that happens, the struts no longer have a window to return to, and there you sit.
It is possible to rotate the window in the brass back to where it belongs, and gently, one by one, nudge the struts back into the slider......... unless the energizer springs also got misaligned.
But IDK if it is possible to do this with the trans installed, cuz you can't really see what yur doing.
The thing is that if it does it once, it will do it again.
You have to prevent overshifting.
How you do that is different between the two covers, but should actually be done at the shifter mechanism.
But the real question is why you felt the need to shift it so violently.

This is NOT a common problem with the A833, so yours is "special"; and will need a careful inspection..
My record for pulling that box on a 4-post hoist is 17 minutes and includes dropping the exhaust pipes and the GearVendor. And I wasn't actually in a big hurry, and it could be done in less time.
No alcohol was involved.

OOPs I see yur faster than me.....
