904 Downshift Squall or Howl

OK, I did not think of the planetaries; they would be putting power back into the engine to spin it up on the downshifts. Trans was supposedly rebuilt by a shop good with Torqueflites maybe 2 years ago and < 1k miles ago, but I am not sure how often anyone would look hard at the planetaries. But the howl does not change pitch at all, so maybe not.
