#370 of 379 Transmission Issue
Nov 12, 2008 (8:15 am)
I purchase my 07 avalon in 1107. It has been a lemon for many reasons, but here and now the tranny. The car had low speed hesitations and clunking sounds as per the other posts. In 1007 the dealer claims to have recalibrated per tsb eg029-07. This fixed the hesitations and clunking; however,my fuel economy has dropped 10-15%. The net effect of this recalibration was to increase the speed/rpm at which the tranny changes gears. So while cruising the blvd at 35/40 mph I am reviving away at 2000 rpm,... rather than 1500 rpm. You get the picture. The dealer and corp have no remedies to offer for this and the other problems, other than arbitration. Good luck with you issues. guyramon

LIke you I too have an 07 Avy, and also like you, had the recalibration done to my car. After reading your post about how your engine was turning higher rpm's lower speeds, I decided to check mine out... here's my results:
35 mph = 1550 rpm's
40 mph = 1700 rpm's
50 mph = 1500 rpm's ( perhaps a tad higher, 1525/1550 )
60 mph = 2000 rpm's
I can also say that I noticed an immediate difference in the shifting pattern, primarily at low end speeds, after the calibration was done.
As for mileage, my normal daily drive is a combination of city / highway and I'm averaging approx. 26.5 mpg... On a recent "short" highway jaunt into texas a month or so back I was averaging between 29 & 30 mpg with the ac on.

W, I'm not sure about a TSB for 2008 models. EG029-07 covers shifting performance for 2006/2007 models (ECM Calibration), and is available at various sites. Just put Toyota TSBs into a search engine like Google, etc..

Thank you for the assist. I could use a copy sent to harvalstohotmail.com before I begin the battle with the dealer.
