I want to put a 4.7l because I wished for a 5th gear, to improve fuel economy. You said I already have the 5th gear I just need different software, how would I go about getting the different software?

Has to be flashed with StarScan tool. Now good luck finding a dealer who will do it.
We had a moderator on here a few years back with an '02 4.7 who lived about an hour and a half from where I am who wanted his 45rfe flashed to a 545rfe. He went to three dealers in his city, two told him this was not possible and the other told him it was, but they wouldn't do it as it made the vehicle non-factory.
He drove over here where my small town, local dealership flashed it. Took all of 15 mins...

Not even close, east coast...
But regardless of what dealer tells you, it can be done with scantool. I dunno if they tell guys it can't because they don't have a clue or just won't.
I had access to a scan tool a when I used to install lift kits for a Jeep dealer and got to play quite a bit. Trust me, there are things you can do that the average mechanic at the dealership hasn't a clue about. More than once I've had to tell a mechanic just what screen to go to for a function.
I PM'd instructions to a member to take to a dealer a few years ago who told him it was impossible to enable DRL's on an '04. Was just a matter of changing the country code.
So yeah, dealer can make a 45rfe into a 545rfe, have seen it with my own eyes...

If you have access to an actual Chrysler dealer StarScan tool or Star Mobile you got it made. Go to the TCM module screen and from there just select the option to flash the latest firmware.
If you know a chrysler tech who can plug a $10,000+ scan tool into your obdii, why do you even need to ask so many questions on a forum?
If the scan tool is an oem, just be advised it won't work until it's been plugged into a dealers network...
