a proper auto you could leave in drive with the handbrake on for 15minutes ina big queue (I admit its not good for the auto g/box) |
D? Dunno. Thing is, a coventional TC+Epicyclic box will just be stirring
fluid, not burning a clutch plate.

Also reversing into a tight parking space on an incline is the major test I find for these systems Why? Is it that it's hard to control speed? I've never driven one. |

Although almost everyone I know who has a Tiptronic type box soon gets tired of playing with the manual change and starts to use the box exclusively automatic. I'd mostly agree,with one exception: I had a BMW 120 auto as a courtesy |
bump up/bump down autoshift), but got into the habit of using manual top
gear on the motorway, otherwise every time you put your foot down
(unless *very* gentle), it would drop gears. A right PITA.

Blimey, things ain't moved on much. The last time I used public transport was as a kid in the late 70's and the old double-decker bus I remember watching the driver flick a small lever to change gears with no clutch. I think there was about a 2 second delay in flicking the lever and the gears changing, so I guess that's probably been modified a bit. I remember those too. I think some semi-autos had a pedal you blipped to |

Me too, also to lock the car in gear when anticipating (down) hills or
bends etc to stop the car running away. A multistory car park a prime
example.

Although almost everyone I know who has a Tiptronic type box soon gets tired of playing with the manual change and starts to use the box exclusively automatic. I know it's horses for courses, and everyone has their own ideas, but having now owned four fully automatics I would never never ever go back to the hassle of a manual gearbox. On the odd occasion these days that I find myself driving a manual (usually hire cars), I find them a pain in the backside. Just *why* does anyone actually 'want' to constantly pump their left leg up and down and waggle a stick about when a modern auto box does it all for you? It's beyond me! Bit like someone preferring to wash clothes by hand instead of in the automatic washing machine!! |
manuals as the constant cog swapping to stay where the power is becomes a
pain, with a petrol engine it adds to the experience plus the sound of the
car hitting the limiter in every gear adds to the enjoyment, but diesels
don't have that.
Diesel auto is a great combination - and should also ensure a long engine
life too.

They had 3 conventional pedals, but the 'clutch' pedal was actually the
gearchange pedal.
You simply selected the gear you wanted with a small lever, usually
sprouting from the steering wheel hub, but nothing happened until the change
pedal was depressed. so once in top gear, you'd normally select the next
gear down so it was ready for a hill or for overtaking, with just a dip of
the change pedal.
I drove a couple of pre-war Armstrong Siddeleys with preselector boxes, and
I quite liked the idea of preselecting whatever gear you liked before it was
needed.
IIRC they were also fitted to Lanchesters, and certainly to the 50's Daimler
Armoured Car.

I drive both, and now both cars are diesel I would certainly avoid diesel manuals as the constant cog swapping to stay where the power is becomes a pain, with a petrol engine it adds to the experience plus the sound of the car hitting the limiter in every gear adds to the enjoyment, but diesels don't have that.

The best of both worlds - the ease and convenience of an auto - but with the
fuel consumption of a petrol manual.

I agree. My present car (as you know!) is a diesel auto, as was my last. The best of both worlds - the ease and convenience of an auto - but with the fuel consumption of a petrol manual. |

Why? Is it that it's hard to control speed? I've never driven one. |
standard automatic, the har will hold position or creep as you release the
brakes, but with a CVT I believe it'll roll forward until a certain amount
of loud-pedal is applied.
