Downshift clunk when going up hill at highway speeds
Does anyone have any thoughts on what might be causing this?
2005 F-150 (5.4 Triton) makes a loud clunk-- feels like hitting an expansion joint for a bridge -- when it downshifts at highway speeds. It's most pronounced when going up hill and stepping on the accelerator.
I've owned the truck for about two years and I think it's always done this but it more pronounced now that I've removed the mud tires. The transmission isn't slipping and seems to shift fine (recently changed fluid/filter).
Thanks!
