Any more info on the hoot noise . I had just stated on the old site before it became useless , that my 09 Escape is a FWD with a build date of 1/09 and has never made a hoot noise and the knocking noise I had was resolved by the cyl head replacement. I think I heard somewhere that the latest TSB for the hoot noise was for both AWD and FWD and wonder if anyone else withe a FWD has the issue.

here's some interesting info on the 09 scape trans.
Quality Tested for Durability
Ford automatic transmissions are subjected to hundreds of hours of durability, noise, vibration and harshness (NVH) testing. A series of accelerated durability trials equate to 150,000 miles of the most abusive customer usage under extreme conditions.
“One test for the 2009 Escape was to run in fourth gear with maximum trailer load at 100 mph for 15 miles. And that was repeated about 500 times,” explained Rich Rej, 6F35 systems engineer, Ford Powertrain Operations. “We determine what the most abusive driver would do to our transmissions and then we do more to it to make sure that we are delivering a high-quality, durable gearbox for our customers.”
Ford also utilizes a state-of-the-art Transmission NVH Hemi Anechoic Chamber that allows engineers to develop hardware to meet noise and vibration targets that will result in a quiet, interior cabin, and yield higher customer satisfaction levels for transmission quietness.
The new 6F35 6-speed automatic transmission is assembled at Ford’s Van Dyke Transmission Plant, which also produces the 6F50 6-speed automatic in 2008 models of the Ford Taurus, Taurus X, Edge, Mercury Sable, Lincoln MKX and 2009 Ford Flex and Lincoln MKS

So if your having problems with your 09 escape give this guy a call.
Rich Rej, 6F35 systems engineer, Ford Powertrain Operations.I'm sure he'd love to hear from you.

What's the latest on the " Hoot " noise ? Are there any FWDs with the issue ?

The TSB includes FWD also.
I've never heard it on mine , just wondering if anyone else out there with Front Wheel Drive only has the issue .

This issue was first said to be with 4WD only and was later expanded to all vehicles and became a transaxle drive chain problem. I had my 4WD module reflashed as per the early TSB but that didn't help any.

If I pull the fuse for the 4WD module, it stops! So, I really wonder if they have the correct solution and that plus the fact that a few that had their drive chains replaced said that the sound returned after a short time.

I now have 5,200 miles on my 2010 and I realized something the other day; my hoot noise is almost gone. When I first got the vehicle, it would hoot rather loudly every time I took off from a stop. After the 10B15 PCM flash, I thought it got a little better but now, it's almost gone. I still hear it faintly every now and then, but nothing at all like it was when the vehicle was new.

FWD or 4WD?

The service book says to check the transmission cooler tubes for the CD4E as they may cause vibrations that change with engine speed.
The "hoot" noise started with the '09MY with the 6F35 tansmission which replaced the CD4E.

Thanks Bill...To my understanding its a pretty solid unit, correct. The majority of bugs are out and this is a rare case re: this transmission?
Most problems have been with the new 6F35 transmissions, shifting issues and leaks.

The "hoot" sound was first a 4WD only problem, a TSB to reflash the 4WD module didn't help mine. A second TSB claimed it to be in "all" Escapes caused by the drive chain in the 6F35. A few had it replaced only to have the sound return after a few miles.

The odd thing is that if you pull the fuse for the 4WD module which disables the 4WD, the "hoot" stops!!

can someone link or post the pdf for the hoot noise? also how would i discover the actual build month of my escape? i have looked up the vin online, but doesn't show build month. some TSB's only note certain months before or after
*edit: I have 09' xlt 4wd. it has 27,500 miles, and i get a slight hoot sometimes from stop, as well as a light whirring noise close to and just passing 40mph.

That is just odd. Is JTEKT still making the coupling, wonder if it's in the coupling itself?
I assume that it's still the same ATC used but at first Ford claimed it was the ATC making the "hoot" then they claimed it's the 6F35 but if one disables the ATC, it stops! It sure sounds like it comes from the rear of the vehicle but it's also possible that because of the driveshaft, it may transfer along it but that's just a guess on my part.

If the hoot noise is also heard in the 2wd vehicles that eliminates the driveshaft telescoping the noise. I have not worried about the hoot noise in mine. Until now. I have been out on rough gravel roads a couple of times recently and while slowly going up a hill, with light power applied, almost at a crawl, the hoot noise is constant and after a while gets a little tiresome. Any harder power application and it stops.

Right, either it's the same sound transfered through the driveshaft to the rear or there are two different "hoots"! I get one "hoot" while leaving a dead stop and that's it. See, if it's constant, you have a different problem.

It is the same hoot, it is at about the same power setting as pulling away from a stop sign but because I'm going uphill it remains at the constant load on the drivetrain and the hoot continues for as long as it has that same load and rpm. When pulling away from the stop sign you quickly accelerate through the hoot noise.
