Hi kwp,
Did you try what Mike R suggested further up in this thread? Jacking up the back and moving the wheel while trying to move the shifter to get it back to neutral? If this happens again to me, that will be the first thing I try.
Anyway, to get the trans cover off, I removed all four hydraulic lines going to the lift housing. Unfortunately to move the pipe that leads to the suction filter I had to remove an additional four hydraulic connectors. I moved that pipe enough for the trans cover to clear. (Even if you could get the trans cover off without moving this pipe, I doubt you'd be able to drop the shift forks down in the right place).
Then removed all bolts for the lift housing and pried it up in front and put a 2x4 block in to hold it up. Then I had enough space to get a wrench on that left-rear bolt for the trans cover. Removed all bolts and pulled it up.
I also ended up draining about 10 gallons of trans/hyd fluid so I could see the groove where the low-range shift fork should go and be able to get that in the right position. It's down on the countershaft, so it's covered in oil at the normal level.
