Replying to: joel16 (Sep 06, 2007 1:08 pm) http://www.answers.com/topic/toyota-vin-codes for a long time, people had been dismissing the transmission issues new owners were experiencing and reporting. interesting how there have been TSBs issued to address problems that weren't "real". so progress is being made. i suspect (but admittedly do not know) that while the TSBs that call for a reflash to the ECU (Engine Control Unit), PCM (Powertrain Control Module), or TCM (Transmission Control Module) or what have you, you're probably not going to get around shift flare without some hardware change to the transmission, shift solenoids or torque convertor hardware... Perhaps you can mitigate greatly hesitation and flare with reprogramming, but eventually, I tend to agree with poster wwest, you come up against some other physics issues related to flow rates, volumes, capacities, surface areas, etc. And I would tend to believe it would be more expensive for a manufacturer for large N complaints to service / swap hardware, than develop and issue a reprogramming. Good luck.

I also wish my Camry would be recalled because of the transmission problem. I had the EG7031 performed and the hesitation problem improved, but the revving and slipping between gears is worse than ever. Today I couldn't get the transmission to shift into 5th (I have an automatic) while I was going 60mph. Stepping on the accelerator only wrapped it up more and I couldn't get it to shift until I braked and tried again. The RPMs were really up there! Is there any other TSB besides the 7031? My dealer says that's the only one. Thanks.

I spoke to them today. They said until Toyota issues another service bulletin there is nothing they can do. However, our Toyota service rep and his supervisor are going to a Toyota meeting in Denver next week and will bring up the transmission problems that they are seeing more and more of lately (not just the Camry, but the Highlander as well). I don't have high hopes, but perhaps something will happen. In the meantime I am to schedule a ride with the service manager to show them what is going on. At least there will be more documentation. Thanks for the reply. I'd never heard of "converter lockup" but that describes what's happening perfectly.

| Problems with flareup/downshifting affect both 4cy. and 6cy. As problems with my 07 Camry LE did not show up right away, I doubt if you will be able to discover problem with just a test drive. However, I would suggest you drive the car to an inclined road, get up to 55-60 mph, set cruise control, then wait and see what happens as you travel up the inclined road. My car displays the problems on any inclined roadway no matter how slight the incline. GOOD LUCK!!! | |

Replying to: jewel2 (Sep 07, 2007 2:47 pm) After your post, I am beginning to wonder if they are confusing my issue with the hesitation issue that people are experiencing on the 5 speed automatic (4 cycl). I say this because I know there is a newer TSB out there for the shift flare that was released in June but I am hesitant to mention this to them...since THEY are the manufacturer and should be telling ME this information!! Anyway, like you, the service manager wants me to come by and reproduce the issue for him (even though they tell me there isn't anything else they can do). I am hesistant to do this too because, this time around, the shift flare is much less predictable. Anyway, we'll see what happens. I am going to try and video tape it if possible. |
