Replying to: ctl (Aug 09, 2006 2:43 pm) Detroit has a bunch of engines that are, by almost any definition, technologically inferior and inefficient - relative to HP,(3.8 GM, DT Ford, for example) yet they are about as reliable as anything out there. In these cases, old must be better? IMO, the assumption that new=good is wrong more often than it is right. The point of the post, though, is to get those who has some transmission issues to read those procedures outlined in the TSB - it may help in some way with reprogramming/reteaching these imperfect control systems. Another case where new does not equal better - don't ever remember anybody complaining about the 'old' 4 speeds. |

Replying to: captain2 (Aug 10, 2006 6:10 am) To a programmer, or say an engineer writing the specification for the engine/transaxle ECU firmware, lifting the accelerator abruptly and all the way would/might "imply" a wish to coastdown to a lower speed. In that circumstance remaining in the current gear would seem most appropriate. The above sequence may even be used to set the stage for a downshift if subsequently the brakes are applied. On the other hand if you simply "feathered" the pedal to a shallower position that, seemingly, would/might imply a wish to enter cruising "mode", and an upshift would likely be more appropriate. Back in the fifties when automatics first began to appear we soon learned that if we wished the transmission (no transaxles back then) to upshift sooner all we had to do was slightly lift the accelerator pedal momentarily. So those of you experiencing this problem might want to practice completely closing the throttle until, if, you subsequently reach the point/decision, to accelerate. Keep in mind that applying your foot higher on the pedal, which seems to have helped in some cases, would require more force and therefore lifting the pedal would likely both be more "abrupt" and a shorter travel distance. Just guessing, again. |

Replying to: captain2 (Aug 10, 2006 6:02 am) why don't we have a Toyota rep in this forum? I mean, did the Toyota rep just stumble upon that forum and joined? I think not. I mean we payed some good money for our Avalon's, why don't we have the same access to that Toyota rep the 07 Camry's have? And, why are they sorta ignoring our problem with the transmissions, but not ignoring the 07 Camry's problems?

Replying to: niteone (Aug 10, 2006 12:24 pm) As far as the tranny behavior is concerned, I really believe that there is either nothing that can be done about it or Toyota hasn't figured out a way to tame these essentially electronic gremlins. As far as VSC and TRAC go, you need to understand that these 'safety' features do - stop you from doing something that IT doesn't 'think' you should! |
