I got an 2003 ford f250 5.4 v8 gas with 82,000 miles on it and the other day when I was driving it, I noticed when I was doing 45-50 mph and when I wanted to go faster the transmission downshift and then upshift real quick. Its not lifted but will be in the future. Will the transmission drop after I lift the truck if I dont get it checked out? Or is it a huge problem to where my truck wont move one day?
