It takes a bit for the transmission ECM to "learn" your habits 500
miles minimum with a new vehicle. What is the particular behavior
you're at odds with?

Philip the car has about 2000 miles on it. First it shifts way to fast on light acceleration. It will be in third gear before 25 mph. If you take off hard it shifts fine. After taking a hour long highway trip, it bucked between 2nd and 3rd gears as soon as we got of the interstate. And it does not like stop and traffic.

Ok. NOW I get it. The "problem" is not really a problem ... rather
a disagreement. LOL Under very light acceleration, my 2003 Corolla
shifts to 4th at 28-30 mph. Under real light acceleration, shifts
occur at 1900 rpm with engine at operating temperature.

Explain "bucked between 2nd and 3rd gears" as this is really not
possible during a shift UNLESS ... you started increasing throttle
pressure just as the transmission was shifting 2-3 .... your
increased throttle pressure making the transmission shift back 3-2
(the "buck"). BTW, you ARE free to use the OD Lockout button on the
shift lever. BTW, since you have the new 5 speed automatic, the
speeds at which 2-3 shifts occur is going to be different than
earlier 4 speed units.

The shift from 1st to 2nd was smooth but from 2nd to 3rd the car would not go into 3rd gear without bucking. Throttle pressure was steady the whole time. Lexus es300 has had lots of problems with this trans, so why they put it in the v6 camry is beyond me. 30,000 dollar cars should not shift like this.

Have you contacted Toyota ... asking for a Technical Service Bulletin
regarding transmission shifting?

My '03 V6 5-speed Camry has a clunky downshift intermittently, and if you shift
from Drive to Neutral it bucks into reverse just momentarily. I bought it from
a very large Toyota dealer, so took it back. They had their best transmission
man road test and computer test it and said it was all normal, nothing wrong.

Later I contacted Toyota and they got in touch with the head of the service
dept., and he did call me back and said that despite a good computer check,
sometimes a transmission would have to be re-programmed. So I made the
appointment, but the mgr was on vacation that week. The acting mgr said they
road tested it and was OK, and that they did not re-program only in case of a
replaced transmission.

I feel I got the royal run-around, and intend to contact Toyota about it very
soon.

I am going to try and get that service bulletin from Toyota. It does not show
up on the web site of NHTSA.

Wayne i thought the 5speed auto was new for the 2004 models with the v6

>Wayne i thought the 5speed auto was new for the 2004 models with the v6

I think it was introduced mid-year on the 03 models. Possibly was introduced
along with the new V V T (variable valve timing) feature on the 3.0L V6, which
I believe is upped to 3.3L for 04.

Mine was built in April 03.
