Default Chevy 1500 Limp mode, then stuck in neutral.

I have a 2015 1500 5.3 4x4

The truck has 132,000 miles with the transmission replaced at 93,000 miles.

The other day i took a 2.5 hour drive(each way) on the way home i could tell my truck was acting up, stopped for food, went to drive again and it wouldn’t shift out of 1st. Check engine light came on, at first i though limp mode. So i disconnected the battery, let it sit, reconnected it and made it home. Drive it again today, shifting hard, the. came to a stop sign, truck was stuck in neutral, wouldn’t go into first or reverse.

Any ideas?

Thank you in advance 🤙🏻

According to Occam's Razor, I think you have a bad PCM.
