Default Lexus ES300 - Motor revs, but car doesn't move - 07-01-2009 , 05:52 AM






Dear Experts,

I'm hoping to find someone who might have heard of
this problem/symptom, and know the solution.

I have a 99 Lexus ES300 Coach Edition, with about 86K miles now.
Automatic transmission. Very similar to a Camry XLE V6.
Bought used last year.

This past week, it wouldn't start without a boost.
So today, I changed the battery. And installed a
powerful 800 cold cranking amp battery. The old
battery had a bad cell.

But even before I did this, I noticed that the
transmission wasn't engaging the way it normally
did. On the way to the battery shop, the engine
started. I put my foot on the brake and put the car
in gear. But the familiar push from the idle was not
there. I had to rev the engine before it moved.

And tonight, when I was driving home, I had to
rev the engine to about 5 or 6 thousand RPM
before it accelerated.

And soon when I was driving down the highway,
any more gas (RPM) would not make the car go
any faster. I was just coasting, and coasted over
to the side of the road. After that, it would
not go forward or backward. Even if the engine
was running at a few thousand RPM.

So, the symptom is that the engine seems to run
fine. Up to 6K rpm fine. But when you put the
car in gear, it won't go at all. But there are
no new lights illuminating the dashboard, such
as the check engine light. There doesn't seem to
be any strange mechanical sound.

Only 86K miles! My Camry went to 180K and the
transmission worked fine.

Does anyone know what would be the cause and/or
solution would be? I'm hoping that it will be
something simple like an electrical issue.
Perhaps the NOX sensor?

Thanks a lot!

First thing to check would be the ATF fluid level.

I was about to ask about the driving habits of everyone who's used the car.
But then I noticed that you bought it used. So much for useful information
about how the car's been treated. Unless the transmission had some kind of
nasty defect to begin with, it takes real skill to wreck it in 86K miles.

So, like someone else said, open the checkbook.

First, check the condition and fill level of the automatic transmission
fluid (ATF). The ATF should be red or reddish-brown and translucent. If it
is black or if there are shiny metallic flakes on the transmission dipstick,
the transmission is probably bad. If the fluid level is low, then add the
correct ATF.

One of the things that will prematurely wear a transmission is shifting from
drive to reverse and vice versa before the vehicle comes to a complete stop.
Shifting directions while the vehicle is in motion has the effect of rapidly
wearing the friction surfaces in the transmission. I see people do this a
lot, and their transmissions rarely last much past 100,000 miles.

An electrical issue would probably cause the check engine light or OD light
to illuminate, and since the vehicle did move for a while, an electrical
issue is not likely.

There is no NOX sensor in the vehicle. Oxides of nitrogen are reduced by
the vehicle's exhaust gas recirculation (EGR) system and a malfunctioning
EGR system may cause the engine to stall but would not result in the
symptoms you are describing.

The engine is equipped with knock sensors. When the knock sensors detect
engine knocking or pinging, the engine control computer will retard ignition
timing but will not result in the symptoms you are describing.

The symptoms you are describing sounds like a badly worn transmission, or if
the transmission was flushed within the past year, then dislodged internal
sludge may have clogged an internal fluid passage.

If the vehicle is not drivable, then a proper diagnosis would require
hooking up a transmission pressure gauge for a series of pressure tests.

Yea like most comments check the ATF level first.
And its condition.
I was never sure how to do this.
Until I checked and found ( told by Toyota Auto box guy )
Run car at least 10 miles.
Leave car idling.
Then check the dip stick level.

I always felt when Toyota filled mine that it was over filled.
But I was not checking it RUNNING.

I hope you find a better solution than opening that Cheque book.

My 1995 4 has 98K miles on now

Good luck

Well it sounds like you have done the most important thing ---- you
put it in gear! That is reallllly important. How was reverse? Did you
try it yet?

Second in importance is to check the fluid and make sure there is
some. If you need to add, put real tranny fluid in, not just water. It
does get hot, but the special tranny fluid cools much better than
water does. And besides, water is just too thin and ... well ...
watery.

Another thing to check is the year of manufacture. The first year of
production 1993 ES tranny had this neat little white ball in it that
used to dissolve around 80 to 90,000 miles. Then the tranny would work
a little bit in reverse and much less in forward. So the cheap guys
would drive their 93s in to the dealer in reverse to trade them in.
Most dealers never caught on believing their own line about how good
the product was. That white ball required a really simple total
rebuild. Just a few thousand dollars. Maybe your 99 was retro-fitted
or maybe it was really a 93.

So the Lexus has a rich history of transmission trouble. They have
always had to try much harder by using at least one more gear than the
German trannies have. But of course the Japanese trannies are just
plain rough, no way around it when compared to the German products
found in true Luxury Karz.

Yes, do tell. Tell me about your 94 ES.
Thanks.

Best find $2500 or so for a trans rebuild.

Ask me about my 94 ES sometime.

Some people sell their cars as soon as they learn of major problems.
And sounds like this is one of them. As stated by others, the simplest
cause can be low ATF level. Just check and add the proper amount if
low. When any 86K mile transmission stopped moving these days, I'd
guess it's either heavily abused or never been serviced.

Another cause is low ATF line pressure. If these A-series transmission
have never been serviced every 30K miles (or 15K in severe service),
then the friction/steel debris in there probably plugged up a few
things. This can cause accelerated wear to clutch packs and brake
bands, and you basically have to do a rebuild.

These inexpensive Aisin A-series transmissions are fairly dirty and
they lack a suitable filtration system (they have only strainers).
That's why they should be serviced (including strainer) every 15K
miles if you intend to keep them. They're kinda flimsy when you push
them, not performance transmissions by any means, but work well in
typical driving. Some owners have reported they crap out around
80-120K miles.

So I'd:
1. Check fluild level and condition.
2. Drop the pan, replace the strainer (Fram ATF kit), inspect wear
particles and wipe pan clean.
Refill with proper amount of ATF. Cleanliness is important here.
See if this fixes it.

Then it starts to get involved:

3. If not, measure main line pressure.
4. Consider pulling valve body and inspect/clean it and slap on a new
VB gasket kit (see local transtarindustries.com) before you consider a
rebuild.

And then it really gets expensive:

5. Rebuild or get a re-manufactured transmission. Call Jasper Engines
and see if they have one for your model/year.

Well, I'd say that about the newer Aisin U-series clunkers. but the
older A-series was generally OK for normal driving, but flimsy when
you push them, especially the differential assembly.

==================

Is Aisin a brand name, or are you attempting to describe where they're made?
