super 55 tranny

[Gary O]

I rebuilt a Super 55 tranny and once everything was back together I find I can't get either reverse. The other 6 forward gears work. The tractor wants to bind up and stall, so it's not like it isn't engaging somewhere. I've taken off the top cover and can see the gears and yes they are in right. I also took out the shifter mechanism and it moves freely. Any ideas why it's binding up in reverse?
Thanks

Just a question. Did you set the preload on the pinion gear assembly when you put it back together? The shifter rails are lining up? I'll check my manual tomorrow.

Does it try to move backwards when in neutral?
