Pushing fluid through switch

[Crazymacks]

Morning ! Have a 5 ton dump, with fluid pushing out of the front end lock out switch on the dashboard, air dropping faster than it should once it hits 120 capacity. Heard a few possible issues, any other suggestions are appreciated, thank you

If the transmission has no other fluid leaks. Then you would need new seals on the shift fork Engagement cylinder on top of the transmission and for the front axle Engagement cylinder which is on the rear of the transfer case Memphis equipment has them

If the the transfer case itself is leaking fluid. Or if you air the truck up and remove the oil fill plug on the transfer case and you can hear air escaping then you have a shift interlock cylinder that is locked open. This is located on top of the transmission

I am thinking the Interlock Cylinder is leaking air into the transfer case and venting the air into the front axle s/w on the dash.
If you look in the TM you can see the interlock Cyl. p/n A1-3261-D-290, nsn 2520-01-134-0899
It is located on the top of the transfer case. Little hard to get to it.
