i'm in the market for a sedan right now. looking forward to test driving the TLX SH-AWD, but i just can't see how I would get it over the IS350 F Sport.

Not quite. It's true that the Ford Focus/Fiesta, Dodge Dart, and a couple of other makes have had trouble with clunky low-speed DCT performance, but it was not universal by any means. The VW/Audi DSG/S-Tronic DCT transmissions, especially the early versions, were as smooth, if not more so, than most torque-converter automatics....even the ultra-smooth automatics from GM and Lexus.

you're right there, the vw/audi dsg/dct is amazing.

maybe GSteg in this post...

was referring to the single clutch autos like the one in an older m3, and even the LFA, which are known for abrupt shifts at low speed.

But I won't drive a car with an inflator kit. With TPMS, how often are drivers stranded with a flat that can hold air from a slow leak? Yes, I have AAA, but if I'm nowhere near home, that's a long tow if an inflator kit can't help me; and if I have the family with me, how are we all going to fit in the cab of the tow truck.

I don't love RFTs, but it's the only way I'm foregoing a spare.
+1 no spare is for cost cutting. Its just spun to make its seem like they're conscious about fuel economy.

Bitkahuna, I think you and GSteg are correct that there's a trade off at low speeds and initial start off with DCT's. There's a lot of slippage and delay, even with the VW units, and right now a huge problem (in my opinion) with the Mercedes unit in the CLA and GLA. Can make stop and go and in parking lot maneuvers pretty maddening. Maybe this Honda application of a torque converter can eliminate that.

Acura delivers an all-new TLX that’s truly tasteful and conservative.

Check out the first modified TLX that we just did! Very clean look with our Silver Polished VFS2's.

My particular experience is with my aunt's VW Golf GTI. It was fine at higher speed, but you do feel some jerkiness when maneuvering in parking lots. It's definitely not bad, but there are some room for improvements. VW had issues with their earlier 7spd DSG transmission, but the later revision seems to be better.

In a car like the M3, the more violent shifting at low speeds is more acceptable because of the caliber of car it is. The TLX however has it right by not only giving the car a quick shifting DCT but a TC for ultimate refinement, which lets face it, the car is more happy racing around suburbia than on the Nurburgring. That said the VW DSG unit is among the better units as just a DCT but it's not perfect. The Focus if you guys remember has a DCT and it's terrible at low speeds, very jerky and often it's Achilles Heel in reviews and comparison tests.

My experience with an 2010 VW CC DSG indicated that it could get jerky around parking lot speeds. Did you test a model that was earlier than that?

Fine--I don't like it, but I'll accept that. But make it available as an accessory. Roof racks and cross bars have been removed for cost cutting, under the guise of fuel economy standards. But they don't give you a ball of twine instead--you can still get a roof rack and cross bars. Don't give me an f---ing inflator kit; I want a spare.

yeah someone i know has a focus with the DCT. she is not made of money and buying a new focus was a stretch and she was VERY upset with the transmission. i told her to return it as a lemon since clearly the dealer couldn't do anything but i think she kept it.

Somehow, though, the VW/Audi units, even with slippage, avoided clunkiness a low speeds. The Fiesta/Focus, and Dart units didn't.

Yes, the first VW/Audi DCT units were smooth as silk....as much so in some cases as torque converters. Later VW units, as you and a few others here have noted (and I agree), did seem to have a slight bump now and then starting off.

Ford has admitted that the Focus/Fiesta DCT units are clunky at low speeds, and has promised to rectify it in the future (but I have no idea how long it will take).

When I did my first Fiesta review several years ago, I noted a hesitation in the responsiveness starting from rest, but I didn't realize, at the time, that it was actually the Ford DCT (as the older VW units had been smooth as silk). I summed it up, in the review, to a (possible) condition of too much leanness in the fuel mixture (which will also give uneven low-speed acceleration problems). That was probably wrong on my part.
