Hello, welcome and thanks for asking your question. My name is***** will do my best to help you on this concern.
From what you are describing, it does in fact sound like a TIPM issue.
As for flashing it, there is a 50/50 chance that flashing will fix the issue.
I have seen times that just clearing codes fixes the problem, other times flashing it fixes it. Sometimes I find a problem with the wiring or the a/c clutch coil is open or shorted. Same thing with the transfer case problem. Other times the TIPM is fried internally and needs to be replaced. My course of action is to attempt clearing codes then if that doesn't help I go ahead and flash update it. If it fixes the problem I charge for the flash, If it doesn't fix the problem I do the flash for free and charge diagnosis to determine if it is a wiring issue or component issue and go from there....
Let me know if you have any additional questions...
