Help, my car goes forward in reverse and neutral

[AJMcCarrell]

Yesterday, I changed out my tranny fluid and while I was in there I shimmed the accumulators. It would go forward in all gears including reverse and neutral, it also downshifts when it's supposed to upshift. I took it back apart and took out the accumulators, I even had a local neighborhood mechanic look at it and neither of us can figure out why it's doing this. The linkage looked fine, the valve body went back together fine, the accumulators went into the right place, as well as the check ball, I used Toyota Type IV fluid. The car drove fine until then. Any ideas?
