June 30th 2006.
As you may know from reading
this blog, I am very concerned for the average car
owner that technology for technologies' sake is
running rampant in the
auto industry.
A sort of "my father's
got a bigger one than your father" run amok in the
engineering department.
Most of my concerns are
centred on electronic overlays of almost useless accessories
and up to now, the mechanical complexity
of various cars has been
comparatively trouble free.
However, there has always
been one area of mechanical design that perplexed me
and that was the trend to six, seven and even
eight speed automatic transmissions.
Why do this? I ask myself.
I know what the Pavlovs
dogs will answer: smoother shifting, better fuel
economy and improved performance.
Maybe, but not always and
at what cost down the road?
It used to be that 70%
of all cars on the road were bought second hand, sorry,
"pre-owned".
That figure may have changed
with the onslaught of insane purchase incentives that
have been the norm of late.
(Why is it, do you think,
that the auto companies losing the most money offer
the richest and most generous cash backs and
zero percent financing
?).
Nevertheless, complexity
costs money.
Up until now, I have always
felt that Toyota was exempt from the old rule: "Never
buy the first years production of any brand new model".
But complexity has caught
up with even the King of Quality.
The new Avalon and the
2007 Camry have run into a tidal wave of complaints.
Mostly centred around the six speed transmission.
Toyota says it's only the
first few. Some owners dispute this and suspect that
the move from a Japanese to an American engine
and transmission manufacturing
factory may be the reason that this very serious bugaboo
has arisen.
For my part, I believe
that the installation of a completely unnecessary
and much more complex six speed automatic transmission
has caught the engineers
flat footed.
The problem arises from
the fact that the new transmission has to fit on the
back (or side, if you wish) of an engine that already exists,
so just like Chrysler before
them, the six speed is stuffed into the casing of
the five speed and many components have been thinned
down, or narrowed down,
so that the exterior dimensions remain the same.
Chrysler never ever solved
this problem. As fast they reinforced one component
another would let go.
Rather like trying to block
the holes in a leaky dam.
Toyota, on the other hand,
is famous for taking fast remedial action and no doubt
this will be done.
In the meantime, if you
can wait, you should, for better news or buy the five
speed four cylinder Camry, which is likely to be more
economical, if not just
as fast.
Of -course, if you want
to be completely immune to these problems, buy a (dare
I say it?) standard shift gearbox with no " tiptronic"
overtones.
Credit due: at least Toyota
didn't go for a CVT which is an even more undesirable
transmission option.
