Hi:

i have a 2006 ford e350 with 5.4 v8 and 4r75e transmission 128k miles

the van stalls occasionally from standing still to first and slips occasionally from 2nd to 3rd.

when cold there is a shudder from standing still, after that occasionally when warm from standing still.

i flushed the transmission with mobil 1 fully synthetic atf, replaced the pan filter and inline filter. also after changing the vss the od off light stopped flashing.

the old fluid was reddish and not black. no burnt smell. will replacing the valve body with a re manufactured one fix this?

any other ideas?
