Napa can order the Lubegard ATF flush if they don't have it on the shelves. Most BG/Wynn shops should be able to sell you the ATF flush.
That seems like a good plan. Add the flush, wedge the tires(back up to a wall tree whatever), start 'er up an leave her in reverse for 20 minutes, then either perform several drain/refills or full Ttec(cooler line) flush. Don't forget to service the filter when you're done.
If the flush helps the reverse slam, I'd seriously consider upgrading to a full synthetic ATF, using Lubegard/Smartblend red, and/or practicing a more frequent ATF/filter change intervals to prevent future issues.
For the ARX to work, he'll need to drive in reverse for extended periods. Not feasible to drive in R on the way to work!
