Almost positive I change the transmission fluid and filter and I've also clean the throttle body and mass air flow sensor and I relearned the idle and transmission shift points when I did so. The outside temperature gauge will also read about 10 degrees off

And how are you going to feel, after having it flashed, if you just to return to the same symptoms?
Rule of thumb - before disconnecting the batt to clear KAM, you should attempt to retrieve all stored codes, pending or otherwise (no CEL needs to be present). This at least gives you a cogent starting point.
Next - did someone say 'Maintenance'? What haven't you done? Plugs/boots, fuel filter, et, etc? Run some Techron? Checked yer VCT solenoid screens for blockage? Checked CMCV actuator function (need a mirror and an assistant)? Rodent nest in the air filter?
Can you describe just how you cleaned the MAF/TB?
In other words - more data is required before you arbitrarily throw a reflash at this concern.

BTW - the PCM has nothing to do with yer outside temp display. That is likely a failing (or even dirty) sensing element.
good luck

What plugs and COPs were used, dielectric applied properly.
Sorry - just collecting info is all - eliminating as much low-hanging fruit as possible in an effort to save you some coin. Does not take much to cause this drivetrain to misbehave - and it's really picky about the quality of parts being used.
For all we know you have separate issues - a trans on the way out, and an engine problem. Hell-fahr, e'en thet li'l FPDM bastige been know't t'booger folks up, lol. Gitchee Mark-1 Eyebawl on 'er an' rule 'er out, aight. Monitor the FP PID.
However - you seem anxious and predisposed to getting that reflash done. I'll not try and stop ye, lol.

Stored codes, Mode $06 data before you cleared the PCM?
