My 07 Avalon had a shift lag problem in lower gears. After a lot of complaining on my part a Toyota representative found a fix in the June 6, 2007 Technical Service Bulletin. They reprogrammed the computer and now my Avalon shifts properly.
Refer to "ECM Calibration: Enhancement to shifting performance and smoothness. OP CODE DESCRIPTION TIME OFT T1 T2 - EG7023 Recalibrate ECM (PCM)"
The dealer will not fix this problem unless the customer complains.link title
#347 of 379 Avalon TSB RE Transmission Hesitation: READ THIS !
Jun 29, 2007 (2:15 pm)
I'm a 06 Avalon Ltd owner. Last Ocotber I posted my near death experience with this car as I merged onto a major highway in NJ. RPM surge, hesiation, transmission surge...all of which forced me off the road to avoid collision. After this incident I called Toyo in CA and opened complaint file, brought the car in for testing and filed a report with NHSTA (acronym order ??). Toyo tech told me that the car was operating normally and nothing was wrong (sound familiar ??).
Recently became aware of the TSB and called Toyo in CA to find out why I was not contacted about the "fix" . After rambling on that this was not a recall, they urged me to bring back to dealer for another "look". I dropped it off at the dealer informing him of the TSB and my discussion with Toyo central. Service tells me there is no guarantee that the TSB will work. When I questioned this he said "other work" may need to be done. Phone call 1 at 1 day post drop off: "TSB didn't work, need to replace electronic valve body in transmission" "This involves dropping the pan, replacing the valve and running diagnostic". "We need car for another day". Phone call 2 2 days post drop off: "Replacement of the electronic valve didn't work, may need to replace transmission". Phone call 3 to Toyo central: "We need to open new complaint file" I refuse, stating that it is the same problem as before which was never fixed. Phone call 4 from dealer: "Transmission needs to be replaced...sorry"
Here it is in a nutshell: If it smells like, tastes like and feels like crap...then it's crap. So to all of you who have placed wooden blocks under the accelrator or hypothesized about the impact of Newtonian physics on the transmission performance...good luck. I now have my $34,000 car with 21k miles undergoing a transmision transplant, performed by 19 year-old DeVry Tech graduates. I'll be sure to ask for the can of spare nuts and bolts when I pick it up. I only ask that the car run for another 11 miles, that's how far it is to the nearest BMW dealer.

Well after 21/2 years I finally have my 2005 Avalon shifting ok. I mentioned to my dealer about the TSB that was mentioned here. They installed the changes (on the 2005 it also needed new exhaust manifold). The car has is finally not down shifting and other funny shifting quirks. They will not address this issue unless you complain about it.

well, I just had this done and according to my wife, it works like a charm....she stated it shifts much smoother with no hesitation at all.....
glad I did this...now I can't wait to get back home and give it a go myself.
btw, mine is a 2006 xls.

Glad to hear this fix has worked for your wife.
Anyone else who has had it done, please continue reporting on your results.
A similar TSB hasn't been issued by Toyota Canada so far. Has anyone tried to have this fix done in Canada based on the USA TSB?
