So I start the ute in the morning, let it idle for 30 seconds or a minute and slowly cruise off to work. When it changes to second gear (6 speed auto) it makes a little thud, like it's in the cat. Then one morning I pop it into sports mode and hold 1st gear and it does the same thud click thing that sounds and kinda feels like it is in the cat. The warmer the ute is, the less noticeable the thud/click noise is. Just wondering what it could be??? Otherwise, I had the climate control fixed when it was a couple months old (Ford fixed it in the March 2010 models, mines a Feb '10 haha). Fitted the lower airbox off an XR8, it comes on boost a tiny bit earlier, sounds a tiny bit nicer, and goes a tiny bit better I know I haven't been on in forever, sorry if this is in the wrong section and already been asked.
