Setting your tire pressures affects your transmission shifting

[Yousuf Khan]

I have a 2000 OBW with 5MT. Ever since I've had this car, I've never
really had a consistent smooth shift from it. I've owned it for 8 years
and shifting has remained jerky since the beginning. It's not a matter
of how smoothly you can operate the clutch, I've tried various different
clutch release and engagement speeds and I still often get a jerk when
going into gear. It's especially noticeable in the lower gears, when
going from a dead stop into first, from first into second.

I just got used to it over the years until recently I played with the
tire pressures a little. I put 34 psi in the fronts, and 32 psi in the
rears. I did this for other reasons, but I was surprised to find that
the shifting had smoothed out completely! The car wouldn't jerk around
no matter how sloppily I used the clutch! This worked for about 2-3
weeks, until I started to notice the car was jerking again from time to
time. I checked the tire pressures, and sure enough the air pressures
had gone down in all of them by different amounts. So I filled them up
again to their previous settings, and shifting was again smooth.

I put in more in the front than the rear because the engine puts more
weight on the fronts.

Thanks Yousuf, i was scratching my head asking myself why 32psi was
speced by FHI for front and
28 for the rear of the 93 legacy.
You might have just found the answer.

I wonder how the reduction in displacement and increase in weight of
the bare bones impreza affected the
shifting. Any reviews with the relevant reference anyone run into?

I don't know if this will work for the automatic tranny, because the AWD
systems are totally different between the manual and auto Subies of the
same model. The manual Subies have a full-time AWD with a limited-slip
diff in the center and in the rear. The auto Subies have an on-demand AWD.

Hey, are you a Dell factory rep?!?!

Damn! A+ rating for the last QTR! Good job!

Hey, are you a Dell factory rep?!?!

OT Hmm, I remember last time I talked to dell they begged me not to
return vostro
even though I have explained that no amount of discounting would fix
the crap buttons on the trackpad. They finally agreed for a refund.

My issue with dell is not service though, servers (rackmounted and
tower based) are
just fine but all laptops including the business line leave something
(a lot in fact)
to be desired.

This is so unlike subaru that does not have crap in the US lineup. JDM
cars are another
story I'm sure. It seems that japs export mostl;y the middle of the
gaussian curve:
total 2 cylinder crap and exra fancy models remain domestic. Just look
at the evo IX wagon
for example.

Yeah, I would love to have a Kei from anybody, but we can't get them.
Would serve my needs quite well.

That's why Toyota and Nissan and Honda came up with Lexus, Infiniti and
Acura, so they could sell the domestic models at prices to justify
importing them.

I've often felt FHI should split their brands/products like
Honda,Nissan and Toyota did.. Put the Tribeca, the Outback, an
'upscaled' Forester(maybe) and the Legacy sedan under the brand
'Legacy', put the WRXes, the OBS and Forester under the 'Subaru' or
Impreza brand - then bring over a coupla Kei cars or similar small/
affordable compacts - maybe one electric or hybrid - and sell under
the brand 'Fuji' or something(kinda like Toyota did with Scion).

(however, I think I read FHI is gonna stop making Kei in Japan so.....)

No, why do I look like one?

One of the techs in the "South" area is Yousuf Khan.

What are the odds?

Pretty high actually, somewhat common name in some parts of the world.
I'm not saying it's anything approaching the John Smith or the Mohammad
levels, but it's fairly common.

Yeah, they are. There are a few around here, not legal for over the road
use but a couple of the colleges use them for on-campus vehicles. I think
they're Suzukis. Cushman sells them under the Cushman brand name but you
can get them from dealers, just can't license them.

There are some older modles that are "grandfathered" in because they were
imported and registered before any laws were passed. You can register the
old 360 van because when they were new they were titled and registered.
Would love to get one of those.

I'd also like to get a Divco and "toyotaize" it!

Be a great marketing tool for my cover band...

Interesting.

What's more interesting is that Bruce and Sheila don't even show up for
Australia...

But Matilda does!

It would be a hard sell in the US considering how good Fit (Jazz) is.
Now as ever with better sound insulation to put some distance between
the driver
and the buzzy 1.5 I4.

As far as A class goes you now get fiat 500 from the italians: again,
japs
will be hard pressed to sell bare bones kei against premium A class.
And then there is the little wonder called MX-5 that's been around for
like forever.
but I'm too claustrophobic for anything smaller than jazz or mazda 2.

Do be glad you do not get daewoo matiz in the states :-]

I never equated the Fit with the Jazz. OK.

The Fiat is a cool looking car, just like the one from the 50's/60's.
The Mazda 2 is also a good little car, as is that new Hyundai they should
be coming out with any second now. THAT is cool!

I also like the Honda hatch with the gas engine with electric assist.
However, it;s gone from $17,900 to $23,000 here!!!
