The 5 speed transmission on my new '03 seems a little strange. If I drive about 35mph and then slow down to about 5mph and than try to accelerate there is a hesitation. It's as if the transmission can not decide on what gear to go into. When it finally does there's a slight lurch forward. Can this be adjusted?

welcome to my world.
this is the one of the same complaints on the 02 tranny. Apparently they didn't fix it.
Search back (in CL) on 02 trannies and you will see a long detailed letter to lexus.com and thier responces concerning this problem.

The whole problem is shift logic. It doesn't shift when we think it should, or when we would if we had a manual or if it were a four speed auto.

There may be some joggling/bucking when going 40 mph in D. The car wants to go to 4 but the logic says stay in 5, thus producing the buck. push the lever over to 4 and it goes away or speed up to 45 and it goes away.

The hesitation is common if you stomp it. If you go 3/4 to the floor you get more acceleration and shifting ot one gear instead of the the drop in 2 gears which brings your rpms right up to 5-6k.

Lexus says its not a problem and the ECU will learn the driver's style and adjust, and most users complain it is and the hesitation can lead to possible accidents. There are complaints on it to NTSB (?NTHB) but I guess not enought to warrant Lexus/Toyota to move on the problem. (I have the web site if needed). Pop an email off to Lexus.com to register the complaint, the more owners that bring it up the better.

take care,

steviej

See, now I thought the 03s were fixed because mine doesn't display the issue, but yours was built after mine wasn't it? Mine was built in Feb.

Weird, maybe I just never drive it in a way to produce the hesitation, but I'm pretty aggressive.

I have a new 2003 ES300 with 700 miles, The transmission shifting pattern seems
> super erratic. If you ever let off the accelerator and put it back where
it
> was, there is a thump with the transmission, also a lot of hesitation say
> from 27 mph when pressing on the accel. Seems like a computer problem and
> engine and transmission have delays in talking with each other. The
dealer

> experience this? It is getting a lot of press, and I even heard that there was a class action suit headed that way. Maybe they can't fix it. It makes me want to trade the new thing off, I dont want to be in a Houston intersection and need to move.

You're not alone. This website does not allow me to put in a link to Club Lexus, so you'll have to find it on your own.
It's under the ES300 Forum- Engine and Transmission Section.- '03 Transmission.
Alan

P.S. Can any of the Moderators from this site tell me why I can't put in the proper link to Club Lexus so the above gentleman can read the thread??? The link changes from club lexus to cublexus. Is there a reason for this little game????

the point of this forum is not for people to direct people away, but to help each other. there are other ways to spread the information than to link to other sites. CL also does not have the best reputation with accepting our links on their site. i am a member of both, and have attempted to post a thread about LOC on there in the past. it was immediately closed.

not sure if it's a game or anything. you'd have to contact matt about that.

I wasn't trying to direct people away but I was only trying to help each other the best way I could do, and that's giving them a link to make it easier for them to get their needed information. It's a shame that these two sites can't co-exist without animosity. I really wasn't aware of this so I'll remember this in the future. :(

my apologies mate.

I was experimenting with the forum software expression substitution functionality, and (as I had just been on that site) was using the phrase clublexus as my experiment.

Clearly, I did not completely tidy up after myself - and left some problems lying around.

Please post the appropriate link.

this isn't the case - I assure you you.

it was a simple case of me not removing all the expression changes - I left one in, this changed the text in the way you experienced.  :blushing:

Please accept my apologies.

Thanks very much for clearing up this matter. I sure didn't want to make waves, especially since I'm a new member of this board. I'm also an Administrator of Vaio VillageMy Webpageand I know these situations arise on occasion. I'd like to be an asset to Lexus Owners Club.  :cheers:

Alan

P.S. I hope you don't mind my putting in a plug for Vaio Village. Our membership is about to reach 5000 members and our purpose is to help Sony & other owners who might be having computer problems. If you have a chance, give it a look. :)

Hi Zeta,

The main purpose in trying to link interested members is to get the word out about this tranny problem so Lexus gets their ass in gear and comes up with a fix. ;)
