Clunking when shifting...

We noticed a slight clunking when the engine shifts from 1st to 2nd at slow speeds in towns. Once on the road and up to speed of course, this doesn't happen. It's not low on any fluids but the check-engine light came on. We had the guy use that thing they hold to check the engine and he said something about the timing may not be right but couldn't really diagnose the problem. All else checked out.

What can be causing this? What does it mean?

You should take it in to a Ford heavy truck facility and get that light checked out. The clunking noises can be many things.

1) Inspect the drive line very carefully, U-joints normally give visual signs before they fail.

Look carefully for any splitting of splitting, or cracked edges of the U-joints. Also look at the intermediate bearing (between front and rear bearing.) The photo is a U-joint on my Ole Toyota MH, the Ford will be larger, but this gives you an idea of what you might see if its failing.

2) Tailshaft and park brake assembly.

The park brake internal bearing can fail and start causing a lot of play on the drive shaft splines, i.e. you can move the drive shaft up and down where it goes into the back of the park brake.

If this bearing gets to bad, it will destroy the tailshaft of the transmission. very bad news.

Park brake assemblies are re-build-able. Usually they fail from lack of oil (they require servicing) but the tranny tailshaft is a big ticket item. Catch it before it destroys the tailshaft.

3) Engine misfire could cause a momentary hesitation that could cause the clunk. You need to read the "Check Engine Code" codes and post them so we can better address your question.

Follow these instructions.

Put unit in drive mode...park brake off but foot on service brakes.

You get in drivers seat and hubby on ground next to unit on creeper with flaslight.

You place shifter in drive count to 5 then reverse count to 5 then drive and repeat if clunk is heard.

If no noise rev engine a little after shifting.

Hubby looks for things moving while you do your part.
