Trans down shifting delay

[Ericw]

2019 1500 5.7 7 speed transmission- won’t down shift from 3rd to second to first until complete stop. Anyone else have this problem?

2021 Rebel with 8 speed trans and I have the same issue. When slowing to a stop sign, the trans shifts down to 3rd and hangs. If I apply throttle, the trans slams into 2nd or 1st based on speed. The truck shouldn't still be in 3rd or 4th gear at 5mph, but mine is.
