Hello
I’m might coming little bet later.
In an 8400 Champion transmission prior to remove the case you should identify the problem?
Every time you engage a gear there are three cloches engaged in a sequence.
In front of the transmission you have the shafts caps and three orifices in each cap
You have to install the gages and run the transmission with the wheels up in the air to find out which clutch it is fault?
To remove the case you jack the grader with your blade and put block under the tires about 20 cm high and that’s will do.
For parts contact us in Ontario Canada, we will supply everything included a rebuilt transmission if you what too?

5th gear forward cloches engaged A-C-H, Pressure should be 215-235 PSI.
