Is it possible to remove OD servo without pulling tranny?

Looks like their isn't much room up there.
I just lost 5th gear, rest of the gears shift fine. code P0775. I have removed the valve body and solenoid block, will probably replace at least the solenoid block (maybe both). While I have it apart I would like to have a look at the bore in the overdrive servo. I really don't think the problem is there though, as this servo is also used on 2nd gear and it works fine. So has anyone ever attempted it?

'01 LS V8 5r55n BTW

Update:

I found a broken spring in one of the valves on the valve body. Anyone know what that valve controls? Or where to get a new spring?
I managed to piece together the old one and find that all the pieces are there. the end of the piston is a little beat up but its not on the sliding surface.

Another note, anyone have a used solenoid block they want to part with? It doesn't have to be working, I just need the temperature sensor (don't ask...).
I may try and reuse this solenoid block with this new finding.

P0775 is 2nd, and 5th solenoid. The pinpoint test leads to solenoid body assy, if you have good voltage, and signal going to it.

Do you know about the Sonnax Pre stoke spring repair kit?? I think that is your problem. Take a look here:

Here is a picture of the parts bag.
