[QUOTE="krabill, post: 133076, member: 23026"] Latest update. Played with the machine a bit over the weekend. First thing I noticed was the Red Transmission error light pop up after using the hydraulics for a few minutes (not BOSS equipped) in the good manual it says this "The transmission warning light comes ''ON'' when hydraulics are operating. (853 Standard)" Cause 1 - The fluid level is not correct. Cause 2 - The hydraulic pump has damage. The Operators manual for this light says: "Transmission warning light - Low transmission charge pressure, Hydraulic filters needs replacing or high fluid temperature. Stop the engine if light comes one. So this sounds pretty bad? I have no idea if this light was coming on before I attempted this repair. I shut the engine off and the light goes off, I can start it up, and even idle the the engine up almost max and the light does not come on again, once I start using the hydraulics it will then pop on in a minute or less. I doubt it's over temp fluid as it happens so fast. My fluid is full in the Reservoir. I changed the two hydraulic filters and filled them with fluid before installing them. I did NOT change the two Silver canister looking "case drain" filters? I think that is their name has anyone dealt with this light before? Could I still have air purging in my system? I think I've ran it < 10 minutes total since the repair. Any next steps to take? Are those two canister filters important to change and might cause this? Do I need to do pressure testing? Kind of sad to see this coming on after all this work. I would hate for this to just blow up my pump at this point. [/QUOTE]
