Touch Control thoughts

[ShawnAgne]

Prior to the rebuild the 100 TC held the L59 deck like a champ. Got everything back together hooked up the A60 and what I'm noticing is if I raise the plow it slowly drops. However if I run the left control lever for the other TC cylinder it holds no problem. So here is what I'm wondering
1. Is this still air in the system?
2. I'm not leaking fluid but is there something leaking in the TC system?
3. Does the pressure release valve on the auxiliary cylinder over ride the 100 TC system and does it just need to be turned up?

Since the left (non-driver) moving it seems to stabilize the lift side it makes me think it is #1.
If it is #2 any ideas what it would be and how indepth it would be to fix it?
Thoughts?
