Odd behavior in 1st gear, about 1,800 RPMs

I have a DCT.

A while back I started having issues where my car would act like it was having trouble keeping the clutch fully engaged while accelerating in 1st gear. It would get to about 1,800 RPMs and start lurching. At about 2,200 RPMs (or after a shift) it would return to normal. Only happened in 1st, as best I can remember.

I took it to the dealer and they shrugged it off as me shifting too early (even though it did it in Drive, too). They updated the software for the transmission. Now I have another problem I'm trying to track down. While doing so, I noticed my car starting to exhibit the behavior I originally complained about and had 'fixed' 6 months ago.

That being said, it is no longer at an alarming level of power fluctuation, but still very noticeable. I've been logging as much as I can about the car for a few weeks now, and I have some interesting results.

The graph below is a small portion of the data.

Blue = Throttle position
Orange = MPH
Gray = RPM / 100

Each horizontal bar is 10 units


This makes it look like it isn't the transmission causing problems, but instead the computer making the throttle jump around! This raises even more questions, as the 'transmission' software update was for the transmission... Right? Or is it possible they're also tweaking other systems?

What mods have you done ? Maybe a custom tune might solve the problem :D

No mods. I wouldn't mind tuning the car, but I can't justify purchasing an SCT Tuner for $600 on an NA car.

After shipping to Canada + exchange rate it's closer to $600. The only thing that's stopped me so far. But North Carolina ain't got that problem!

I would not even consider a tune until he resolves the clutch engagement issue.

The tune may just exacerbate the problem.

Hey zehkaiser,

I'd like to connect you with your regional customer service manager, who'll work with you and your dealer to come to a resolution. Please send me a PM with your full name, best daytime phone number, VIN, mileage, and servicing dealership.

I'll get this up the ladder.

Todd

OK. So I got a call back from the dealership. I have mixed feelings about the situation.

On one hand, they replaced my steering wheel chrome and airbag (had a bit of peeling). That was nice.

On the other hand, they experienced the shudder I was complaining about, but it isn't bad enough to be repaired. I was told that the tech was able to log that the RPM difference was at 160. The limit for repair is 250 RPMs.

I'm not sure if that means that the transmissions is actually slipping a little bit, but it isn't "bad enough," or that there is play somewhere that can cause it to look that way. I'm baffled, but I'll keep logging my data and if I see it get over 250 RPMs regularly while I'm still within my 60,000 I'll take it back and try again.

EDIT: Had a longer conversation with the tech at the dealership. It isn't the RPMs of the transmission, but the RPMs of the shift drum. He said that most cars he has checked are typically between 210-230, and that mine being at 160 is really good.

I'm glad your dealership was able to replace your steering wheel chrome and airbag. If you'd like, you may visit another Ford Dealer for a second opinion. Just let me know what you decide.

The RPM of the shift drum? Really? It sounds like he doesn't know what a shift drum is and what it does. But that's not surprising... he is a transmission tech at a Ford dealership, LOL.
