tz,
That clicking noise was indeed the parking pawl trying to engage. It's pretty hard to break one off and I'll bet it's OK except for being a little more rounded on it's corners now. The parking pawl snaps into notches on the outside of the annular gear ring, another pretty robust part. Here's the bottom line: If it works now then no real damage was done. Park the car (e. brake not applied) and see if it will roll, if not, then the pawl is OK. Not one single car with an automatic transmission has ever gone more than 100,000 miles without, at some time, having it's parking pawl engaged while the annular gear was still turning. (How's THAT for an absolute statement?) For some folks it's a daily occurrence and when I used to get into their worn out T37s the parking pawls and annular gears were dandy.
Now if you put the car in park and it will roll (sometimes it must roll a few inches before the pawl engages) then maybe you did snap the pawl off. I recall (?) that extensive disassembly is required in order to remove and replace the pawl so that means that from now on you'll have to rely exclusively on the e. brake for secure parking, big deal. You can drop the rear pan and look right at the pawl and annular if you want to see them and if is snapped off that might be a good idea so you can clean the bits out.
The noise at speed is another, almost certainly unrelated, condition. When you change something and a strange noise results immediately it's reasonable to assume that the noise is related to what you changed. Did they put type F fluid in there? Is it really full when hot, idling in neutral? Did they drain or check the final drive? is the final drive full up with gear oil (or 10w30, either is OK, best to stick with what it always had and don't mix the two)? If you have noise coming from a final drive with low fluid you had better fill it right now or you'll have a boat anchor living under your engine instead of a transaxle.
Hope this helps, cheers.
