Default 4l80e won't shift into 4th occasionally

Driving normally i never have an issue, if I get on it then go back to driving normal is when i occasionally cant get the car to shift into OD. Its a 2000 transam and computer tuned with hp tuners. the trans still functions normal in whatever gear its in it just wont shift into 4th. that after a few minutes or after I shut it down it will be back to normal again.
