2003 9-5 auto shifting issues in 4th & 5th

I've got a 03 9-5 aero automatic with shifting issues when I hit 4th and 5th. If I stay in 1,2,3 using paddles it's perfect.

When I hit 4 sometimes it drops to 2 instantly, sometimes I get a delayed shift to 4 and then drops to 2. Rarely I can get to 5 and then it's a guessing game. Might stay in 5, mostly drops to 2.

When this happens it almost always throws a input/output shaft speed mismatch code and sometimes goes to limp mode.

I have swapped TCM, Flushed fluid 2 x complete, and don't know what the next best step is.

Also, the transmission had the screen filter pierced as it was clogged and blocking fluid flow, causing transmission pump cavitation noise. An external filter was installed. Would not drive prior, and got 2000 miles after this fix, then lost 4th,5th to this new issue.

Am I screwed?

Thanks for your input 🙂
