700R4 Problem

Just got my hands on a rebuilt 700R4 for my Jimmy. Installed it in the truck and it does not move when shifted into OD. All other selections work great and even once you get going in D you can shift into OD and still make forward progress. Another funny thing, if I sit there with my foot on the brake, shift into OD and gas it, sometimes it will "kick" into gear. Any ideas on what it might be?

I have done further research and I **think** it may be a leaking forward accumulator. Anyone had experience with this? How about replacing it, easy or difficult? I think it can be done by just yanking the valve body, but I'd like to confirm that. Anyone? Bueller?
