Blocking 3-4 Accumulator

[KEhrhardt]

I think its the 1-2 accumulator spring from a 727 transmission

Hrrmm... not sure Pete. But I do know that others have used the piston and the white 1-2 spring from the 700R4 for the 3-4 accumulator in the 2004R. There is also a "performance" 1-2 spring for the 700R4 that could be tried. Right now there is a wimpy green spring in there. The good news is I was able to remove the plug using the heat gun, but it was a battle. Time to buy some stock in Loctite, that stuff sure works good!
