Deere 4520 steering

[thundergas]

We have a 2007 4520 with approximately 3000hrs on it. When it's cool and or cold out the steering requires multiple (like many turns) to keep it going straight. Several years ago we reached out to our local Landpro dealer and they had no clue what the issue might be. Once warmed up enough the steering is fine. Fluids are up to level and there is no visible leaking at the cylinder. Any clues?

Just two thoughts.
Time since transmission oil and filter (clean screen) change ??

If not the problem, then I'd use a bit of the John Deere Friction modifier in the tranny oil.
Has solved a problem in my 4x2 Gator and also my 4300 sub compact tractor.
