John Deere 5320 with power reversal wants to roll when in “Park”

[Kmicah40]

My JD 5320 is gradually get worse when you put it into Park. Not an issue if you’re on mostly flat ground, but if on a slope and you put it in park most times it will start to roll. When it starts to roll a clicking sound can be heard. If I have to park on a slope I always use the front end loader bucket to raise the front end up enough that the tractor will not move. Was wondering if there is a mechanical adjustment that can be made or is this issue something that requires new parts to correct the problem. Also, is this problem something that requires a skilled mechanic to fix. Any help would be appreciated. Thanks Larry H

Problems with the park pawl on gear drive tractors require a tractor split. It could be on the power reverser you can get to it from the top. I've never done it so I can't say.

@Kmicah40
Are you sure you’ve got shifter completely in park while stopped before you let off brakes ?
My 5101E will do this ratcheting clicking sound IF / When I don’t Properly do this method while parking on a hill.
