I bought my 07 Avy in Sept. of 06. Kept reading about, but never really experiencing the "slipping transmission" problem. However there were a few times that at very low speeds, I did notice some sort of "hesitation". Like I said it was pretty much an occassional thing, certainly not something I noticed daily, that is until recently. Then I noticed it nearly every single day. Started researching tsb's on the net and came up with the following tsb number : EG029-07 This tsb was issued by Toyota for 06 and new avalons. So when I took my car in yesterday to the dealer for an oil change, I asked the service writer about the tranny issue. His reply was there had been some issues with the camry, but not the Avalon. Imagine the look on his face when I presented him with the TSB # which specifically deals with the Avy. They called it up, I was right, they performed the update and now it seems to be running correctly again. Hope this helps some of you with 06 or newer avy's dealing with slipping transmissions.

| My 2007 Avalon was purchased in November of 2006. I had the ECU reprogramed within six months of purchase and it has been just fine since then. Hopefully you will have the same long lasting result. | |

| i would love to get a copy of the transmission TSB for the 05's, but for the life of me, i cannot figure out how to PM. | |
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

Replying to: guyramon (Nov 12, 2008 8:15 am) 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. Roland |
