#10076 of 14965 Re: Transmission issues - Toyota software fix? [jok]
Nov 11, 2005 (1:42 pm)
I was reading some of the other Lexus and Toyota forums and there are many complaints about the transmission - going back to 2002. I am going to discuss with my dealer. Apparently the "fixes" I have read about are available in Canada and Japan but not in the US because they affect emissions.
Interesting reading at http://www.toyotanation.com/forum/showthread.php?threadid=102636
One post is particularly interesting, because the writer discusses "complete loss of gear" which I experienced too. Copy of post is below:
"Since purchasing the Avalon in early June, I have been frustrated with how the car operates between 20 and 40 miles per hour. The car does not always know what gear it needs to shift into. It will frequently race 1000 rpm ahead without any change in speed. Then suddenly it will accelerate and the rpm’s will drop back to normal rpm.
It seems to happen most often in rush traffic when trying to change lanes. The hesitation in acceleration will cause me to lose most of my margin of safety in the process of changing lanes. In this regard, the car is not safe. There is no way to predict when the problem will occur, and therein, lies the safety hazard.
It would seem that the last effort by the service department to update my computer programming failed to achieve any level of improvement to my satisfaction with one exception. Since the last computer upgrade, I have not experienced the complete loss of gear at high speeds.
Is this a problem in all 2005 Avalons? Is Toyota aware of the problem and do they plan to resolve it?
Serviced on Friday, October 21. Toyota reset the computer learning back to factory default. Technical support in CA explained that there are no current plans to address the issue. Once the learning process develops a bad pattern, it must be reset back to factory default and the relearning started over."

Nov 11, 2005 (2:55 pm)
After just having caught up on reading the last few thousand messages on this board it is apparent this car suffers from a veritable plethora of problems ranging from bad transmissions to malfunctioning "little doors" to vibrations and rattles from the audio speakers to a horrible navigation system, etc., etc., etc.! What a mess!
And to think the smug Canadian Toyota dealers, at least in B.C., will not even budge from the excessive MSRP and act as though they are doing you a huge favor to even sell you one of these rigs, is a real trip!
Glad I did not get suckered into buying one and my sympathies to the rest of you who did.

With my 98 Sable, a layman's way to fix such transmission issues is to disconnect the battery overnight to erase the PCM and all...then reconnect it the next day and drive like a manic for a few days so it "learns" to be aggressive with the shifting.
It seems like the Avalon would do the same thing? Since it also "learns" how you drive? Anyone tried it?

Yes, the laser cruise control is rather abrupt sometimes, but not always. Even worse I think is resuming speed, which often invokes a downshift of 2 gears, lots of noise and fuss. This happens especially when you are going uphill. They need a more intelligent controller.
Despite all that, I still like the LCC. Use it all the time on high speed freeway cruising (I5 on west coast). The 5 mph increments initially bugged me, but now I like them because it's easy to adjust to changing speed limits for road construction, etc. When the limit drops from 70 to 55, just 3 quick taps and you're in business.

The problem could possibly be a word that starts with t and ends with l.

ahh, the wonders of technology! Now have 15k+ and have not noticed any hesitation that I would consider dangerous. But, then again, I do drive my Touring somewhat aggressively, even to the point of manually shifting the car maybe 30 or 40% of the time (around town). It may cost me a little gas but not a whole bunch because most of my miles on the highway anyway. Our engines have a wonderful sweet spot between 4-5500 rpm and it would be a shame if there is something in some software that gets in the way. Wonder if you folks can't 'retrain' the silly tranny computer in this manner. Not an excuse for what may be a bad design, just an idea to get around it?

My acrylic lens works great. Put on 6000 miles with it in place w/no problems. I popped out the fairing in front of the LCC unit and duct taped the acrylic lens in place. See posting #8290.
#10084 of 14965 Remove Toyota name on trunk
Nov 11, 2005 (7:23 pm)
I did not like having Toyota on the trunk, so I took some fishing line and slipped it under the letters and sawed up and down and it comes right off. Save it on wax paper and you can put it back, just has some goo on back
