411B Case-O-Matic problem

I recently picked up a 411-B with the Case-O-Matic drive. Nice tractor, but it is difficult to get into gear without grinding. I noticed that when the "clutch" pedal is pushed, the torque converter pressure gauge does not go all the way to "O". It appears that a small amount of pressure remains in the system when the pedal is fully depressed. I adjusted the pedal linkage at the valve but it was no help. Any suggestions?

The book calls for a maintained converter pressure of 30-40psi for the 411B. I can't find anything about 0 psi with the pedal down. My new 801B has the same shifting problem, but the pressure is only 25 psi, and not the 45-55 psi called for, and it doesn't change with pedal movement. All pressures are at operating temperature. The tractor won't idle at present,either. I'm going to change the oil & filter, and fix the idle problem and hope for improvement. My lube dealer said the replacement for 10W MS-DG is Citgo Tractor Hydraulic Fluid Red. ($20/5 gal.)
Buy the I&T Shop Manual #C-201.

The Case-O-Matic in my 600 is also hard to get in gear too. Its hardest to get into 1st and reverse. I have the best luck idleing it down, then putting it into 3rd or 4th. I then quickly shift it into what ever gear I need.

It could be one of two things. The first being that you should have the engine at idle speed before you shift gears. The other is whether or not you have the correct fluid in the Case-O-Matic. The manual calls for either 10w nondetergent,or type A automatic transmission fluid. One trick I used to use was to put the transmisson in the gear I was going to use before I started the engine. After everything was warmed up the transmission would shift better. Ok,I guess that's three things. :-)
