Are we forgetting that Toyota issued a TSB in the spring of 2003 describing 3 of the EXACT circumstances wherein the 1-2 second engine transaxle delay/hesitation was/is likely to occur? Isn't it pretty obvious that if you never encounter any of those EXACT circumstances you are likely to feel you have a "perfect" Toyota? |

http://www.toyotanation.com/forum/t197136.html 06/07 Avalon owners are all to familiar with the jerky/sloppy shifting and acceleration of these vehicles. There have been countless complaints about this on different forums on the WEB. Yesterday I purchased a one day subscription to -> http://techinfo.toyota.com looking for resolution to another issue. At that site I found all TSBs - trouble service bulletins. TSB EG029-07 was released on 6/6/07 and deals specifically with the shifting/accel issues on 06/07 Avalons. If your vin precedes VIN number 4T1BK36B#7U243331 this TSB should help. The 10th digit in all vins is the year, so this should definitely help all '06 Avalon owners. The # sign in the 9th digit represent a check digit which will vary from car to car. I would have attached the entire document, but this site does not allow it. Here's a brief part of the text at the front of the TSB: To enhance shifting performance and smoothness during acceleration, the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) calibration has been revised. Please use the following procedure to address customer concerns. You may see the enire PDF in the Avalon forum at: http://www.tundrasolutions.com or at least until the forum moderators over there remove it. A txt version of it follows - not as easy a read as the pdf at the tundrasolutions forums, but data nonetheless: ************************************************** ************************ ENGINE Technical Service BULLETIN June 6, 2007 Title: ECM CALIBRATION: ENHANCEMENT TO SHIFTING PERFORMANCE. & SMOOTHNES.
