Discussion Overview

The discussion revolves around the feasibility and desirability of reintroducing pushbutton transmissions in modern vehicles. Participants explore various aspects including design choices, user preferences, and comparisons with current transmission technologies, such as paddle shifters and continuously variable transmissions (CVTs).

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants recall positive experiences with pushbutton transmissions in older Chrysler models, noting their functionality.
  • Concerns are raised about the practicality of pushbuttons for users with long fingernails or limited hand strength, suggesting that they may not be universally user-friendly.
  • One participant suggests that the prevalence of large shift levers may be a marketing decision rather than a necessity, as modern designs do not require such mechanisms.
  • There is mention of alternative designs, such as gear selectors on the steering column, which some find convenient and space-saving.
  • Several participants discuss the merits and drawbacks of paddle shifters, with mixed opinions on their effectiveness and user experience.
  • Some participants express skepticism about continuously variable transmissions (CVTs), sharing personal negative experiences and questioning their popularity.
  • A reference is made to a Dutch car manufacturer, DAF, which produced a belt-driven CVT that had issues with belt durability, illustrating the challenges faced by such technologies.

Areas of Agreement / Disagreement

Participants express a range of opinions on the practicality and desirability of pushbutton transmissions, with no clear consensus on whether they should be reintroduced. There are competing views on the effectiveness of alternative transmission designs, including paddle shifters and CVTs, indicating ongoing debate.

Contextual Notes

Participants highlight various user experiences and preferences, but there are no definitive conclusions regarding the superiority of one transmission type over another. The discussion reflects a variety of assumptions and personal anecdotes that may not apply universally.

I used to be a happy owner of Chrysler cars with pushbutton transmissions. They worked very well.

Today, the center console of my car is high demand territory. I resent the excessive console room taken up by the shifter.

What prevents reverting to the pushbuttons? Is is the PRNDL federal standard?

Alternatively, what prevents moving the shift lever up to the dashboard as shown below?

Sounds like you should get a BMW equipped with paddle shifters... :smile:

Fascinating wear patterns on the shift buttons. Presuming the buttons preserve grime from the driver's fingertip, reverse appears most used or used first, followed by neutral than drive. Drive1&2 appear pristine.

Apropos the original question, I remember pushbutton shifters and complaints from some drivers. The buttons were difficult for drivers with long fingernails, weak hand strength, and could be slippery to operate.

Well, how about a Dodge Ram 2022? (bottom right corner)

The list goes on and on.

Funny anecdote about the 60's Chrysler push button of the OP. My uncle used to own one like in the picture and the transmission broke down. He replaced it with a used one from a newer model, but it had an extra 'Park' on the shifter and the cables did not fit anymore. So my uncle let the cables hang under the dash and he was pulling the cables by hand to shift the transmission!

I suspect it's a marketing decision. People must like a big shift lever. The days of needing a big lever to pull on a linkage to the transmission are long gone.

You've kind of answered your own question in it's formulation: it's not necessary, but the auto designers still do it. Just like your radio and cup holders.

Paddle shifters are common.

The shifter on the dash is too far to reach. If I'm resting my arm on the center armrest, my hand naturally falls on the shifter. I have an automatic now but it still sits there.
 
Why shift in discrete gear ratios? Get an EV with start, reverse and stop buttons.

You forgot to mention the Insane Mode button... :smile:
 
My Merc has the gear selector on a stalk on the column. It's really convenient...once your muscle memory commits that the right side stalk is not the indicator stalk 🤦‍♂️ But it does free up space on the centre line console, so I don't understand why more manufacturers don't take advantage of buttons over a large knob shifter.

Oh, and I have paddles as well, but the 7-speed DSG transmission overrides my choice at the red line and at slow speeds, so I rarely use them. Also, I've grown out of the 'boy racer' stage of life!

Doesn't seem to match up with this...

You've outed me, @berkeman 😂

Nah, seriously, it's a 1.4L turbo engine pulling a solidly built German hatch, they seemed obliged to include a "Sports" mode - hence the paddles - despite the fact that unless you trip the turbo the car is a slug! So, all the Sports mode seems to do is keep the revs over the turbo threshold, meaning the engine sucks down petrol like a thirsty sailor, howls stupidly even when you're cruising along, and holds an upshift for some Teutonicly precise number of milliseconds longer than it otherwise would. Oh, and still controls the gears because, God forbid, you pick the wrong one!

Now, I will admit to very occasionally opening the sunroof and playing Muse's "Uprising" at high volume (the car has a 1,400W Harmon Kardon stereo, that's pretty nice) while in Sports mode. It is as close to a boy racer as I come, though, sadly, our speed limits are really low, so all that gets me in the end is a little bit more deaf, a bigger bill at the bowser, and startled looks from passersby!

That has a single discrete gear ratio. If you want to go away from discrete gear ratios, you want a CVT.

I had one of them once, nobody wants a CVT, @cjl 😉

Seriously, it was a little Honda Jazz, great design, one of those 'small on the outside, big on the inside' cars, but the CVT was diabolical. You could never trust it off the mark, it was ultra-sluggish, so pulling out during a gap in traffic became a cross your fingers and hope endeavour. Thinking about it, it also had paddle shifters, and they were even less useful than in my Merc!

(Also, I suspect you were not advocating for CVT, merely pointing out that they don't have gears.)

As in CVT? Sure, for me it does, @DaveE, but I read a lot of news and reviews about them after buying the Honda and my summary is that if they were fantastic at their job, every auto would be a CVT!
