my SD just started doing this about a week ago. when i put it in park i can hear the pawl clicking as if its trying to catch but the car keeps rolling forward (or back) so i have been using the parking brake. how hard is it to replace the worn metal parts in the trans?

I'd change the plastic shifter bushings first.
pretty simple to do if you have a floor jack and jack stands, or car ramps.
as far as fixing a pawl issue with the transmission, a junkyard replacement comes to mind...

one of the guys I work with ALWAYS shuts down the car in D, rolls to a stop, and then puts it in Park after the vehicle is no longer moving.
hypermilers usually shutoff the engine prior to stopping as well... inertia don't burn any fuel!
I hate it when somebody uses park to stop the car from moving... ugh!

reminds me of the scene in The Terminator where sara conner slams it into park while reece and t1000 are fighting through the windshield...
NO WAY it would have stopped... or smoked the tires... it would've just gone BING BING BING BING over and over until they hit the wall...

A former co-worker of mine was driving carpool and was driving his wife's brand new boat of an Olds, RWD with a big v8 while his Mercedes was in the shop. His Mercedes had the four speed column shift, and the Olds was an automatic. At the top of the onramp, he instinctively went for third, and park did engage for a brief second before it sheared the rear of the trans case. Sometimes they do engage-

As for the original question- Shift linkage bushings. This is a known issue, I got mine with "transmission problems" because of these bushings, I drove it for a couple months then parted it out. Use the parking brake, if your bellows seals on the cables are in good shape there won't be any freezing problems.

did the car stop, or did it just break the transmission and keep rolling?
it will blow my mind if an american automatic transmission parking pawl stopped a fast moving car!!!
