Discuss the causes and fixes for P0973 Cadillac OBDII Code

Had a PO973 code on a 2004 Cadillac SRX. It wouldn't shift out of gear. Once you let it parked for a while It drove fine and shifted fine. It happened twice. Trans fluid had been changed at 100,000 miles. I then changed all three shift solenoids with filter and fluid and noticed a definite change in shifting to the better. Vehicle has 155,000 miles on it, and shifts solid and easily between gears now. hopefully no other damage.
Shift solenoids are getting hard to find at the GM dealers and I had to pay a premium price to get these but knowing that they were made for that transmission was why I didn't got for an after market parts company. I hate doing things twice. Just some advice from a person who had a code PO973.
