Got a 2014 Chrysler 300 SRT and it has Sport and Track mode on the screen. When you engage track mode the trans will hold the gear you're in if you're using the paddle shifters until you hit the paddle shifter for the next gear. When I installed the Trinity performance 93 octane mode the unit said I had to downgrade to a lower PCM flash number to get it to load on the car. I did this, got the program loaded. Car feels and sounds good but I lost the trans function that holds the gear until you hit the paddle shifters. I get to 6400 rpm and the trans shifts anyway whether you want it to or not.

Is there an update lately or one coming for the Chrysler 5 speed that fixes this problem?

It's not really track mode when the trans shifts on it's own.

if you get the tcm updated by a dealer it should come back, but it sounds like the device doesn't support that specific cal.
Which device are you using?
