347BLKCAT Posted April 30, 2011 Share Posted April 30, 2011 Anyone heard of any issues with the torque converters in the Aisin 6 speed? Just a thought... 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted April 30, 2011 Share Posted April 30, 2011 No, I haven't. They replaced my TC. It made no difference. This isn't to say that the TC isn't causing your issue, which I strongly suspect is a different one from the one in this thread You haven't mentioned whether or not you've taken your car in for service for this. 0 Quote Link to comment Share on other sites More sharing options...
347BLKCAT Posted April 30, 2011 Share Posted April 30, 2011 I have not taken it in yet as I wanted to research this issue a bit to see if there were any TSB's or any other info on these issues. quote name='drolds1' timestamp='1304181430' post='41529'] No, I haven't.

blueoval4life Posted May 8, 2011 Share Posted May 8, 2011 I thought that i'd throw my two cents in. I drive a 2010 sport awd and I have just under 32,000 miles on the car and I also get that same "vibration" when I reach 35 - 40 mph under normal acceleration. Under heavy acceleration the "vibration" does not happen. This is my first awd car and thought that its "normal". 0 Quote Link to comment Share on other sites More sharing options...
_10579 Posted May 10, 2011 Share Posted May 10, 2011 "It's normal" is the excuse I got after $7,000+ of repairs. So, I guess it is normal! 0 Quote Link to comment Share on other sites More sharing options...
347BLKCAT Posted May 10, 2011 Share Posted May 10, 2011 Seems ridiculous! I find it hard to believe nobody can isolate or identify the problem. I would pay to take it somewhere to get an answer but where the H does a person turn to? quote name='_10579' timestamp='1305030671' post='41885'] "It's normal" is the excuse I got after $7,000+ of repairs.

I would pay to take it somewhere to get an answer but where the H does a person turn to? Read the whole thread. The problem was identified over a year ago. It's a result of the rear differential disengaging at the same time the TCC is locking up. This causes the monetary shudder. It's a software issue. I was assured that a report was made to the engineers in Dearborn and that a fix would probably be found but that it would take time b/c any change like this had to be submitted and approved by the EPA. Well, here we are, a year later. Nothing has happened and this story was apparently a steaming pile of BS. If this really was the case, why would Ford continue to spend thousands replacing expensive driveline parts in other customers' cars when they supposedly know what the issue is? Dealers would inform owners that no repairs would be done pending a TSB. I've spoken to my SM several times. He says that he has reminded the FSE a couple of times and that the report was made. He says he'd like nothing better than to fix the problem, as they get paid well by FoMoCo for warranty repairs. I called him again last week. Nothing new. He says that they get no complaints and, frankly, most of the Fusions they sell are FWD. We didn't discuss it but my impression is that a higher proportion of MKZs around here are AWD. I rarely see a FWD MKZ. I guess all of these people think it's "normal" as well. I voiced my disappointment in Ford. The impression I take away is that they just don't care about keeping a loyal, long-time customer, such as myself, happy. All he can do is sympathize. I know him a long time and this is the 9th car I've purchased or leased from them, aside from the ones my son, daughter-in-law and friends have purchased there. Not to mention that my son is an employee of the dealership. Obviously, we go back a long way. He promised to bring it up again. All these folks would have to do is tell me they're trying and I'd be happy. It's this apparent indifference that irks me. This is simply unacceptable. 0 Quote Link to comment Share on other sites More sharing options...

By that time the rearend has disengaged. It happens well below that speed. 0 Quote Link to comment Share on other sites More sharing options...

This is under light acceleration we've beaten that facet of it to death earlier in the discussion, so there's no point in rehashing it. You made your point clear previously. 0 Quote Link to comment Share on other sites More sharing options...

Okay, I just reread a bit of this thread. I do remember it now. Bet nobody has tried the simple test of pulling the fuse on the 4WD/AWD module to see if the problem persists?

These types of AWD systems were never designed to be 'disengaged' at driving speed ( maybe when parking or when emergency/parking brakes are engaged). I am not surprised if the disengagement feature was forcefully incorperated into the 3.5L sports model only to make it more appealing for some customers ( like wptski, lol) and possibly EPA requirements to save at most 1 mpg under certain driving conditions.

What??? Is that a typo??? Is supposed to engaged/disengaged when the system detects the need or lack of. They do wind tunnel test and add things for less than a 1mpg gain. Look at the front edge of the rear wheel well on a >09' Escape some time. The little rubber piece was added for very little mpg gain but it was added never the less. 0 Quote Link to comment Share on other sites More sharing options...

wptski Posted May 15, 2011 Share Posted May 15, 2011 (edited) It was answered by me about 2 pages back. Okay, I see that now. I actually replied to that post where they disconnected the plug at the rear end, the hard way to do it. There is a so-called "hoot" sound first heard from the rear of the '09 4WD Escape, TSB to reprogram didn't help. later said to be in 4WD, FWD, I4 and V6 from drive chain in transaxle. The replaced chain only works for a short and the noise returns. Owner's are being told it's normal now. Pulling the fuse for the 4WD module stops the sound. Go figure...

I said I wasn't going to hash this over again but your theory would be right if this was 1985. The Aisin TF 80 has TCC lockup on 4th, 5th and 6th gears. So, obviously you're going to get TCC lockup before you reach a constant speed. Give it a rest already! 0 Quote Link to comment Share on other sites More sharing options...

Lucas718 Posted April 27, 2012 Share Posted April 27, 2012 DId you guys ever get this fixed or are you just living with it? I just got a 2012 Sport with AWD and I thought I noticed something around 40mph the other day. I didn't discover this thread until today, so I can't say for sure if the problem is on my car or not. I only have 212 miles so far. 0 Quote Link to comment Share on other sites More sharing options...
packrats Posted May 8, 2012 Share Posted May 8, 2012 Have had my AWD Sport for 2-1/2 years and just seemed to get use to it. Never really became an issue with me because I was aware of the rumble-groan from complaints with the MKZ's. No AWD system is without flaws. I recently had a tech on a test drive and he admitted most of them have the issue to some degree. Mine is most noticable in colder weather. My new Edge with almost the same awd system is quiet so far at 3000 miles on the clock. Just enjoy the drive! 0 Quote Link to comment Share on other sites More sharing options...
