Odd sound - what is it?

[wordsmyth]

Roger that on having it checked. I plan to have them listen to it when I next get the oil changed.

We owned a Windstar van that made a similar noise for over 100,000 miles and while it was annoying, the vehicle ran fine for as long as we owned it.

Okay. Took it in today and it's a bearing in the torque converter. They are pulling the tranny and going through it, replacing whatever.

They are providing me a loaner vehicle until the Ranger comes back.

sweet. glad Ford is taking care of you and thanks for posting back what the issue was. This might help someone else down the road.

Well ... we are mystified. Especially me.

The tech pulled the tranny, took everything apart and looked and it all looked good. When he put it back together he replaced the torque converter.

After he reassembled everything he reinstalled fresh fluid and got it going - the noise is still there.

He can't find a similar noise in any other Ranger on the lot. Two other techs listened to it and said "we can hear it but can't pinpoint it."

Listening to the engine with a stethoscope (ear-pod on a brass rod) he can't hear anything in the motor.

Thoughts?

Whomp sound in ours turned out to be the torque converter not being lined up correctly with the engine crank. The pilot bearing/recessed hole the snout of the torque converter mates up with? Was slightly out of round. Put it back together, and it was rubbing slightly on the bushing. Made a whomp whomp whomp sound at different temps and RPM's.

Not saying that's the problem here---but it's an idea?

That's certainly a thought to pursue.

We had a same-type sound in a Windstar van we owned years and go and it never got worst that an annoyance in the background.

What eventually happened with the vehicle you are referencing?

It's our current B2. It lasted about 3 months that way. I even picked up a replacement spacer plate because I was told that was the issue (the last idiot that worked on it? junked the plate)

The front bushing ate itself and the torque converter 'snout' was badly scored. I took the bell housing to a shop and had them press in the bushing and install the pump to spec. And used a brand new torque converter. The transmission did great until it hit overdrive...and it couldn't stay in overdrive, it kept jumping in and out of gear.

I dropped it and found the overdrive unit ate itself. Shavings all over creation. We had the converter fully flushed until squeeky clean by a shop and used it in the replacement transmission. This time I replaced the crank pilot (which I should have done in the first place---it would have saved dropping the tranny twice and a torque converter.)

Oddly enough? The unit in now? Was the worst looking a4ld I've ever seen. Gunk caked all over it..and dirt inside the pan from where it looked like someone put a funnel into the dipstick hole and took it to the beach.

It's actually been installed for over a year now and working decent. I hosed it out with about 5 cans of brake clean, and used engine degrease on the housing. It still works. (slight hic-cup if you hit the gas just right it will jump into a lower gear in an odd fashion) But I'd trust it, it's my daily driver after all.

Sure it's not the driveshaft? Just a thought.

Well, since you asked the only thing I'm sure of is that I have an inexplicable noise to figure out.

Re, the driveshaft: how would that factor into the "only makes the noise in Drive or Reverse" scenario?

The noise is heard when sitting still in D or R, but not after starting to move.
