4l60e Lost 3rd and 4th fine

You may remember that I posted an issue a few weeks ago about losting 3rd/4th after the car has setup for a period of time and the PCM was bad so i had to wait for a new one b4 testing. Well, I have 4th so that is reassuring since the packs must be fine. So what does it sound like .

Based on the charts, is appares the 3-4 clutch doesn't want to engage while the forward sprag is holding. So lets hear the guesses before the tranny man gets it

PS no codes thrown
