During light city driving my Flex attempted to go into fourth gear and just reved.
I let off the gas and it calmly went into gear. 
This happened 3 times... a bit concerned.

I disconnected the +battery post and grounded it over night to reset comuter.
Has not happened again but the shifts are a little harsh on light throttle.

Any ideas on what is happening?

No codes?  When was the last time you changed spark plugs/transmission fluid etc.?  Datalogged recently?

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

No codes, plugs 5k ago, drain and fill trans 8k ago.

Nothing strange in the datalogs that I can see.

Do you have anything to look for other than line pressure?
