overdrive light flashes and trans shifts hard
Ford f150 2wd 300 i6, overdrive light flashes and trans shifts hard, turn overdrive switch
off and trans shifts smooth. Scanned and got codes p0171 and p0174 you can delete
codes and truck will run and shift fine for 10-20 minutes and then the light starts flashing
and trans shifts hard again. Changed fluid and filter even though fluid looked new and was
not burnt and no shavings or anything in the pan. Thank you for any help.
