Agreed. I mostly notice it when im casually driving. When i put my foot down the shifts are crisp and theres no slippage.

Perhaps it's an issue with how I drive my car, but I generally ease into acceleration, but when I do that the car almost never down-shifts. I'll moderately push the pedal down 75% and the car will bog down in fourth gear. If I push 90% it double-down shifts to second and I take off like a bat outta hell. I find it's very had to downshift 1 gear while easing on the gas.

I attribute the "You gotta learn how to drive the DCT." statement to these quirks. But grinding? Not an issue with "learning how to drive the car."

Let's hope this is normal. Maybe the Ford rep could comment. Cory?
Hi dan50,

Cory is working on a new project so I'll be stepping in to assist.

Since I'm not a mechanic, I'm not in the best position to answer technical questions. Your local dealership's service manager is a great resource for determining whether or not your vehicle's behavior is normal.

F1 cars do NOT use DCT or dual clutches at all. The gears are very, no make that VERY slim and would not last very long in street use but then they don't have to last very long and they make them as light as possible to reduce weight, and more importantly, moment of inertia. The trick to F1 gear boxes is the shifting mechanism that can complete the shift in much less than 25msec, some say as low as 10msec. There is no micro slipping between gears...

Crystal, you are such a kidder! Ford service departments will declare pretty much any DCT behavior "normal" if that's the convenient answer.

Welcome back.

The pinto exploding with a rear impact was "normal" as well I guess.

The DCT twice has shifted so hard in low speed traffic that it felt like I was rear ended, in fact it was a worse lurch than the coulple times I have been rear ended, and I only have 200 miles on the car so far. Hopefully it gets better with use because if not it's unacceptable.

Microslip is to be expected, so it that tiny burst of torque when you shift up or down to keep things smooth.

As far as reliability goes, I'd take anything from this forum, VWVortex or any other site with DCTs involved with a grain of salt since its really the people who hate them who have issues.

As far as the 100k without issues nonsense, VW has been using transverse DCTs for a lot longer, I've heard of no horror stories. A friend has a longitudinal DCT and also has never had issues in 4 years so really, I'm unsure what to make of all the paranoia around them.

I don't know if It can be said that Ford's version of VW's DSG is one and the same. I do know that VW has extended the warranty on all DSG or S-tronic transmission for 10 years/100,000 miles. Yeah and they've been at it with this tranny far longer than Ford. Do we have the same coverage on our less proven DCT?

And at least with the VW DSG you get super quick shifts too.

Ford should extend the transmission warranty but will they?, I am not sure

I think it will take a class action lawsuit to get Ford to stand behind the tranny, honestly, although there is a chance bad press might force it if it slows sales, the focus is selling pretty well right now though.

That or enough people filing a complaint that the tranny makes the car unsafe. There are over 100 complaints already.
