Hello I have a 2003 f150 with a 4.2 v6 automatic trans. It had 108000 miles on it. I noticed last week when I'm at a stop sign and begin to take off it chatters as if the trans is slipping. Is this accurate as it seems like low miles for transmission problems. I have had the truck from 23,000 miles till now and have done all the maintenance. Just curious if there is a easy fix or if I'm pulling the trans to rebuild it.
