A DCT control design flaw

Post by Busterboo » Tue Jan 16, 2024 1:50 am

OK, so you're in 3rd, with the DCT gearstick to the left, in its equivalent of manual. You stop quickly, because there's a herd of elephants charging towards you and, understandably, you slam the gearstick into reverse. What happens? Well, actually, you die, because the stick won't go into reverse unless you push it to the right into auto first.

I'd forgotten about this until it happened again today. Not a serious problem, because elephants weren't involved - there aren't many in Leicester - but it's not hard to imagine a situation where you need to stop and reverse fast out of trouble, but can't, because you haven't remembered the counter-intuitive stick shift.

A DCT control design flaw

The other day you moved your seat to the highest setting available to be able to make full use of your new headlamp bulbs…thus driving with your head so high your eyes must have been bang in line with the windscreen roll bar rendering the bulbs useless anyway as you wouldn’t have been able to see…period. After which you apologised to the manufacturer of said headlamp bulbs for criticising their performance with your seat in a normal position…

….now this….

You are completely certifiable Buster….not because of those things you said you did, because you clearly didn’t…but for your mindset for making up such unfathomable shite….:poke: :poke: :rofl:

Why is a tap to the right and a push forward with button press more complicated than the manual equivalent involving up to 3 stick movements, a pedal push and, depending on the car, a simultaneous pull up of the stick?

I think it's an intentional thing on all cars to make engaging reverse something that is difficult to do accidentally, as it's not really something you want to do while driving at 70 down the motorway.

Try driving an early 2000's mini with a well used gearbox and you'll find out what a flawed design is, as you neatly reverse into the car behind while attempting to pull away from traffic lights.

Anyway, good luck avoiding those elephants, my thoughts and prayers are with you.

My first car (Mk I Fiesta) had nothing to differentiate between first and reverse. It was always a pleasant surprise to find forward movement when attempting to pull away in traffic!

Back when I was at school, my mate was driving his dad's small Datsun (yes, it was a long time ago!), and pretended he had a manual gearbox. First gear, foot hard down, Second, foot still down, missed Drive and hit Reverse. He stopped quite quickly :oops:

Everybody who has pushed the stick to the left has probably been a bit confused when trying to select reverse. Not sure if it mentions anything in the manual about it. My X6 is the same.
