You can download the maintenance schedule (as well as an owners guide) from the Ford Fleet website. Just click on the "Maintenace" button and follow the prompts. I've never understood why anyone would remove this material from a car they don't own anymore What good does it do you if don't have the car? Hope this helps.

I'm a "Zainiac" too but I'm a little puzzled as to why you feel the need to restrip. Dawn is only supposed to be used before the initial application of Zaino. As Sal Zaino states on the website : There's no need to strip Zaino. In fact, the beauty of Zaino is that the more layers you put on, the better it is. Besides, Dawn does nothing to remove Zaino anyway. The only thing that removes Zaino is isopropyl alcohol. If you feel that your paint is that contaminated that you need to clay, then you would use Z-AIO. This serves two purposes. It cleans the paint and lays down a base coat for Z-2, etc. This eliminates the need for the old Z-1 as well. You can even stop after the application of Z-AIO and leave it as a last-step product (LSP), but I never leave it at that :D It's addicting. I top that with Z-5, Z-2, Z-CS and Z-8. BTW, if you haven't tried Z-CS, you must. Amazing. Spray, wipe and walk away. Lasts me 6-8 months, but my car is garaged. Happy "Zainoing." And no, I don't work for Zaino. Just a satisfied customer for many years. Whenever my kids ask me what I want for Father's day or B'days, I just tell them to get me Zaino gift certificates. Easy for them, great for me.

Well, they worked on my car the whole time I was away. The field service engineer arrived on Monday 4/5 and drove the car with the tech. The FSE confirmed the problem, but they have no fix for now. It's now turned over to the engineers in Dearborn and I'm told I'll have to wait until they arrive at a solution. I spoke to the the tech when I picked up the car. They replaced the valve body, torque converter, TCM and rear differential with no improvement. Ford told them to stop now. They know what's causing the rumble: the rear differential is disengaging at 40mph, at the same time that the torque converter is locking. This is causing the TCC to pulse. It's "lugging" if you will. They are both convinced that a few lines of programming code will remedy the problem. However, the change will have to be submitted to the EPA, as MPG could be affected. It takes the EPA about 6 weeks to respond and there's no guarantee they'll approve it. If it's approved, then they have to implement it. So, they had my car for about a month, replaced thousands of dollars worth of parts with no immediate solution and we're without a solution for now. However, both the dealer and Ford have been bending over backwards to make this right. I have nothing but praise for both. We'll see what happens. You'll all know as soon as I do. In the meantime, if you have the rumble and it bothers you, get it documented. If they come up with a fix, I think it's a safe bet that there will be a TSB. They assure me it's nothing more than an annoyance, but if you're as picky as I am, you can't ignore it.

The TCM was replaced on Friday. No improvement. They drove another 2010 MKZ from stock and it did not exhibit the rumble, although I don't recall it happening when mine had no miles on it either. More discussion with Ford ensued. Ford asked when the issue first occurred and I can't recall exactly, but it's been several months. I'll be away all of next week and they'll be able to work on it some more. They've had my car for 3 full weeks now. Maybe they'll have arrived at a solution when I return. I'll post an update then. BTW, I've been driving a 2009 Grand Marquis loaner. I've developed a grudging respect for it

The new torque converter was installed. The problem remains. They're awaiting the next step from Ford. The SA said that it could just be a inherent characteristic of the car and I might have to live with it. After spending $2500 (valve body-$1500 + TC-$1000) so far, that would make great sense on Ford's part, wouldn't it? We shall see. Stay tuned.

Hello, all. I've been lurking here for some time. This thread seems to have died, so I thought it was appropriate for my first post. I have a 2010 MKZ Sport AWD, build date 7/09, that started to exhibit the rumble at 40 mph a while back. I waited for my first scheduled maintenance to have it looked at. It now has about 6200 miles on the clock. The tech had no trouble verifying the rumble and the service manager told me that he had felt it in his car also. Of course, he really didn't give it much thought as he gets a new car every few months and his father owns the dealership as well :P They have a certified master automatic trans tech who was assigned to work on the car. He wanted to just replace the trans, but Ford nixed that. They first wanted him to replace the valve body. He said he didn't think that this was the source of the problem, but they have to do what Ford says. The valve body had to be FedExed from MI here to NY and it was installed earlier this week. The tech reported that the rumble was improved but was not gone and that he would not return the car to me. So, back to Ford. Now they want him to replace the torque converter. This is again on order and should arrive today. He doesn't expect this to be the solution either but again, they have to follow Ford's instructions. If this doesn't do it, then Ford will approve a new transmission. In case you're interested, a new transmission costs $7G! I know this because my son is a parts specialist at the dealer and he just had to order one for an AWD Fusion that was in an accident that damaged the trans beyond repair. It strikes me kind of funny that I'm the first one to complain to the dealer about this. It's an F-L-M dealership, so they've sold their share of Fusions too. I guess the average customer doesn't even notice it, but I've bought/leased 9 cars from this dealer and am known for being particular. My wife had no idea what I was I was talking about with this. I'll keep you posted on further developments.
