Why my Honda is so powerless on uphill driving?
leolee
I have 1989 Civic, automatic. I have no major problem.
One problem is driving uphill. I can't pick up more than
30 miles/hr on uphill driving. It feels like the transmission
is stucked on 30 miles/hr. Sometimes RPM suddenly goes up to 5,000.
Do I have a transimmison problem or what? If I do, why I don't have any
problem on flat road driving.

Is it a real steep hill? your car has anywhere from 83 to 100 (Si) ft/lbs of
torque. not really a whole lot when you get down to it.....this may be the
reason why.
leolee
yes I have to say more steeper hill gives me more problem. I wouldn say
driving on long little steep hill is OK> Waht is the torque?

increase the power. It sounds like the transmission is ok. However, there
is one possibility that slack in your throttle pressure cable to the
transmission has increased. It would cause the transmission to stay in the
high gear when it would need to be in a lower gear to make it up the hill.
One way to check this is to press the accelerator to the floor from
standing still and note the rpm when the transmission upshift to 2nd gear.
It's ok if it's within 300 rpm of the redline. Otherwise, tighten the slack
a little so that the transmission is a little bit more responsive.
I drive 2 stick and one auto Civics. They're ok on flat grounds. When it
comes to going up a hill from standing start, they require a lot of
patience. When I go to skiing in Big Bear, I have to be in 1st gear on
certain sections of the road. The Civics would not make it in 2nd gear.
When I go up some houses on a hilltop, I have to use 1st gear. The hill is
just too steep.
Try to time your 0-60 mph on flat ground. Is it ok?

you mean while engine is running and shift the gear in Parking and push the
gas as far as I can?

you mean 3000 rpm??

Are you saying that cvic automatic is too weak at 2nd gear in uphill driving?

Yes, I have no problem on flat ground driving. LIke going into freeway,
I've never had problem on flat surface.

From a stand still, while you're in D4. From a stop the tranny will be in
1st, acclerate then note the RPM when the tranny shifts into 2nd -- should
almost be near redline.

No... From a hard acceleration, RPM should ALMOST redline..within 300RPM
of it... (i.e redline at 6500, should shift by 6200, for example)

accelerate from a red light behind a guy who drives an automatic. Would be a
whole lot better if everyone drove standards.

take an automatic (Shhh!). I miss my stick. I often go to dealerships to
test drive the sticks for fun. Heh

move fast enough...then again what do I know :o)

not related o production cars, current F1 semi-auto boxes change gear in
~40ms IIRC. The trouble is that with small engines/cars and their gearing
and resulting higher RPMs a fast gear change is difficult to do with smooth
drive take-up. As a result small engine autos tend to spend a long time
spinning the torque converter - that familiar feeling that the engine is
turning faster but the car is going slower.:-)

because most ordinary drivers *hate* abrupt shifting. The ideal for most
is a tranny that feels like a CVT.
As far as the difference in speed between autos and manuals, I've driven
behind many, many poorly driven manuals where the driver practically
buried the car's nose into the pavement with each gearchange. Manuals
may theoretically be faster, but it most certainly requires a much
higher level of skill to realize this speed capability. It's my belief
that most drivers are faster when given an automatic.
I had a fun stoplight drag with a new (or almost new) Corolla S the
other day. He had an auto, and my '91 Integra is manual. My front bumper
was about 3 feet ahead of his the whole way until I backed off at 60mph
in a 50 zone. I'm almost 40; shouldn't be doing that any more!

Hehe, had a good laugh the other day when a guy driving a third gen vette
stalled out right in front of me when the light turned green.

True, only because most drivers today can't drive stick. But it takes only
about a month to become completely fluent at it. It only takes about a week or
2 to get down a perfect 1-2 powershift. 2-3 takes a little more practice, might
catch 5th a couple times or god forbid, first. But take 2 owners of the same
cars, one auto, one stick, the stick will be quicker every time.

Yes but with small engines it's even worse. A big engine/flywheel can at
least absorb some of the jolt of a quicker drive take up without any
mechanical damage. With the smaller engine they have to be "kind" to the
mechanicals too.

Again, with a big engine very likely, especially with modern auto
transmissions, that an auto would be faster. I once had a loaner Integra
with auto while my car was being worked on and it was awful - couldn't get
out of its own way... a total waste to put an auto in such a car IMO.

The real trick here is to do this where you know there's a good chance of a
cop in the weeds up the road and let off just at the right time so the
other guy gets the ticket - very satisfying:-). It was even better in the
days when radar detectors were effective - probably the biggest gloat
moment I can remember when this stupid bloody woman who was all over the
back of me got ticketed while I, at the first beep, had pulled into an open
slot in the traffic in the middle lane and braked down a nice docile 58MPH.
