2004 5.4L E4OD. +200K miles. Had 1-2 upshift issue (upshifted better when taking out of OD, get mph up and then turn OD back on it would upshift; also a delay in upshift if left in OD - usually after warmed up) no other issues. No Codes. No Flashing OD light. Replaced all the shift solenoids, filter kit, and a new spring and piston in the 1-2 shift accumulator. Test drive - all gears present and smooth shifting. ISSUE: When in Park it will still roll forward. Replaced the shift position sensor/switch on the trans and still has the issue. Tried shifting without the linkage/cable attached and same issue.
