5r110 problems

I have a 2005 F350 6.0 with auto. I'm having transmission problems. I have no reverse and only 1st, 3rd, and 5th. I have a bunch of codes:
720- output shaft speed
722-output shaft speed
756-SSPC-B solenoid (overdrive clutch)
2700-coast clutch system error
2701-overdrive clutch system error
2702-Intermediate clutch system error
2703-driect clutch system error
2704-low/reverse clutch system error
I removed the OSS sensor and measured the resistance and it seems to be good. When I clear the codes the 2 OSS codes only come back when I put it in reverse and rev up the engine and the truck doesn't move.
I checked my line pressure and they are good at idle in all gears. The truck is in bolivia so I am limited on what parts I can get. I'm just trying to decide if I need to do a full rebuild or if there is something else going on.

Re: 5r110 problems

sounds like the thing is toasted. I'd pull it and go through it, especially if it doesnt move at all in reverse.
