Others can reply about the engagement issue, but don't waste your time or resources changing the trans fluid. That horse is way out of the barn for a flush to make a difference.

I had an issue with my 08 CSS downshifting from 3 to 2. It would grind. While I had the engine out to repair bore scoring, I sent my trans to a shop in AZ to get the 2nd gear synchro replaced. It was shot. As he dug further into the trans, he found a tooth on the pinion gear was chipped and then he found the 3rd & 4th gear synchros were past their prime. I ended up buying a reman trans. Hope you have better luck with your repair.

Trans guy told me to replace the trans fluid every 10K mi. I do 2-3 DEs / yr. 10K mi might be a bit of overkill, I'm going to do 15K but that's way earlier than the 50K it had before I changed it the 1st time.
