I have a 2010 f150 2wd with 4.6L 6speed trans, 80k miles. It shifts hard from 1 to 2 and not as hard from 2 to 3 but after that it shifts great! 1-2 is hard enough to make truck jerk. Ford says its normal but my boss has a 2009 same engine and trans and miles and his shifts great trough all gears. Any ideas?
