loud clunking
Hey guys i have a 03 supercrew with the 5.4 engine in it. It has about 84,000 miles on it. The problem is when i am cruising down the road and give it gas to pass someone it make a hard clunk and shifts really rough. it only does it when it kicks down maybe 2 gears basically wot. It will always do it around 50mph up to 70 mph. Any ideas what it could be the truck does fine except for this problem?
