Dk50 shuttle shifter won’t come out of reverse

[Wap530]

Was mowing and stopped to back up and shuttle shifter went in to reverse just fine and backed up. When I tried to shift back to forward the shifter wouldn’t move. I can go in reverse just fine. Changed hydraulic filter and there was quite a sediment buildup on the screen going out of the filter. Wiped it off but made no difference in shifting. Where can I find the pressure relief and neutral relief valve as that was a suggestion as to the cause. Does anyone have any other ideas as to where to look for the fix to this problem? I am ordering a service manual but really need fire protection now so any help would be appreciated.

Did you carefully check all the linkages? I've had mechanical linkages bind up.

The DK 50 is synchronized shuttle (mechanical shuttle, not a power reverser)
Far as I know it doesn't have those.

We will check the linkage. Waiting for a service manual We don’t know much about fixing it yet. Thanks for the insight.
