The trans of my 2002 ES 300 hesitates between first and second AND between second and third gear, especailly when in stop-and-go traffic, or going around a corner on a green light. The dealer says it performs according to factory specs and they need the factory to come out with re-programming guidelines to fix it. In the mean while, LExus Corp. customer care reps are in 'denial'. Anyone else notice the trans can't seem to make up its mind to shift up or not when driving in mild acceleration situations?

I've seen plenty of complaints concerning the new 5spd transmission. Yet neither the dealers nor Lexus corp. seem to acknowledge it. But I assume the number of complaints is very minor compared to the number of ES sold.
It seems okay to me, but I'd love an updated transmission program.
I know they've done that for other Lexus cars in the past.

Thanks for your reply. I just got a call from the Lexus folks who are now beginning to say that they have heard of other such concerns from owners and they are in 'the process' of looking into doing something that may result in a Service Bulletin. I just hope all the slippage between shifts that has occurred won't result in premature trans failure. Time will tell.

The problem you discribe sounds dead on with what I'm going through. I purchased my 2002 ES300 in mid Feb. I was told by the dealership it would correct itself after about 1,500 miles (time required for the computer to adjust to my driving style..I was told). When I didn't see any improvement. I went back to the dealership and test drove two other 2002 ES300. There was no sign of the problems I've described below. I would think if it was a programming issue all 2002 ES300 would have this problem.
Issues with transmission.
When the car shifts from gear to gear the power transfer is anything but smooth. The timing of each lull and surge is always different based on speed, acceleration, and road angle (uphill, downhill, level).
Symptoms:
When in Stop and Go traffic, going 5 mph, braking to 3 mph then back to 5 mph - the car lunges forward after a brief pause every time.
When in the range of 55 mph to 60 mph keeping the foot on the pedal but slightly backing off to slow down and going down the backside of an overpass the transmission flutters between what I believe to be 5th gear and 4th gear for about 2 seconds. This is inconsistent and doesn't happen every time.
Accelerating hard from a dead stop the car shifts the best. But this isn't normal driving conditions. Slowing down and speeding up especially in the lower gears causes a pause and a lunging engagement into the gear.

Purchased our ES300 in mid March. Almost immediately called the salesperson to express concerns about safety re: acceleration "lag time" and lurching between 20-30 mph and also between 40-50mph. Salesperson told us to "give it time" for car's computer to adjust to our driving style.
We just now returned from the service dept. They told us that "almost ALL owners of 2002 ES300 have complained." It is a huge problem and "Lexus is working on a fix, but can't determine if it is a transmission or computer problem. They claim it is mostly an intermittent problem which they therefore are not able to study (!). Our car, however, consistently duplicates the problem so they will call a factory rep from CA to drive it.
We seriously feel this is a safety issue. We had a terrifying experience while trying to merge w/ a semi on the freeway and got no acceleration when we needed it.
Please advise as to your experiences so far! THANKS!

Gregg, I sent you an email w/ further information. Please check your private messages. After owning the car for 2 months (5000 mi), our Lexus dealer bought our car back, refunding exactly what we had paid, including the tax. Hope the information I sent is helpful to you.

Sounds like at least Lexus is admitting to the problem and trying to address your issue. I've had that hesitation problem on my 2000 GS400 since day one but Lexus said that was "normal". I even test drove 4 other GS400 and they all exhibited the same problem. So far Lexus is not admitting there's a problem at least on the GS. It irritates me when Lexus tells me it's normal when you know something is not right. Good luck you guys.
