[QUOTE="D2Cat, post: 1708886, member: 19322"] Sounds like you lost prime at the pump. You can take the inlet pipe off at the pump and dump some oil into the pump. This might help in the future. This fellow was working on an M4500, but had the same problem. [B]Problem solved[/B] thanks everyone. It was indeed the hydraulic pump needed priming. I don't know how there is a procedure for these, unless a new hydraulic pump draws enough vacuum to fill the filter reservoir. Or like Dave said they are vacuumed. Other wise they are impossible to fill because of the S-bend design and if you do try to fill the filter canister at the pump end it just goes back in to the sump. The canister is much higher than the transmission. The solution which worked for me( may help others) is I backed up to a very steep incline so the transmission was higher than the filter, I cracked the inlet at the pump, some oil came out and the 3 point hydraulic primed up and started to work.
