Need help with JD 440B skidder

[Cliff Wishnowski]

Does anyone have the schematics of part no. T44643? I bought this skidder with this part off and I don't know where all the lines go. Two lines come from the brakes and one goes to this block which has part no T44643. There are other 440's here to look at but they are standard and mine is a powershift. Thanks
