2013 Porsche 911 Carrera Cabriolet: Transmission Is Clunky at Slow Speeds

January 1, 2014

2013 Porsche 911 Carrera Cabriolet

I've written before about how our 2013 Porsche 911's automatic "PDK" transmission is one of the best ever built. And after over 20,000 miles it still serves up incredibly quick shifts that are always perfectly timed.

But it's not without its issues. Recently I've noticed that it seems to be getting a little clunky at slower speeds. And by slower speeds I mean parking lot speeds, roughly 5-10 mph. There are occasional "thunks" from the gearbox that remind me of our long-term Nissan GT-R. That car also had a double-clutch automatic gearbox, but it was clunky from the start.

Our 911 merely feels like it has loosened up just a bit, something you only notice when it's trying to slip the clutch during a three-point turn. The rest of the time it's business as usual.

    Ha, I get some sort of award for being out in front on this? Regardless of the fact that Edmunds is preparing to transition this car out of the LT fleet, it would be a service to readers (and better serve the purpose of testing cars long-term), if they were to take this thing to the dealer and in a nice way explain that the behavior Ed outlines is not acceptable in a car with 21k miles on it, and relate to readers the result of that complaint.

    It'll probably go like this: "Porsche of Santa Monica ignored what we actually said and just flushed the transmission fluid to make us feel better, for $900, but Bill our service advisor was kind and courteous, so an overall good experience."

    @quadricycle: You really think a transmission fluid flush at a Santa Monica dealership would come in under 4 figures?

    @quadricycle: harsh!...a first for you, though. But accurate. Edmunds staffers are routinely eaten alive by service personnel at dealerships.

    @stovt001: No clue on what they would ask! It bogles my mind that such pricing can exist when there should be plenty of other options in such population-dense areas to check that trend. I don't see a real reason either, since wages and part costs are stat

    @fordson1: Ha! Definitely didn't mean to have that read harshly. It was meant to be small measure of humor in light of Edmunds staff's docility in dealer relations and of your renowned castigatory manner.

  • Normally when a car loosens up from use, it gets smoother not jerkier to drive. Obviously the transmission needs to be looked at.
