2000 F150 4X4 automatic xmissn. Suddenly the indicator has shifted. Now "P" is "R", "R" is "N", "D" is "N" and "D" is "2". I.e. everything has shifted down by one gradation. I suspect this is the linkage. Checked out the fluids. All is good. I do have all gears (although I have not attempted to get it to go into "1"). Any help?
Thanks.
