john deere 650H travel/steer issue

hey guys im new on the forum, have a 650H that is very slow on the right side for the first few minutes after it has sat over night, problem goes away after you travel forward & back for 3-6 minutes & then operates normally after that. i gave the codes to a service manager & he said they all have to do with calibrating so it prolly needs to be calibrated. But that makes no sense to me since it goes away in a short while. the codes are :

F373

F321

F375

F324

3K3

THANKS!:confused:
