When I bought my BMW (used) I wasn't disappointed about a single thing about it............EXCEPT that it didn't have fold-down rear seats. I guess it's one of those things: when you need it...you REALLY want it! Mike |

Replying to: ls09 (Jan 14, 2009 9:24 am) "The TCM determines the gear that is to be selected when the accelerator pedal is released (released completely) in accordance with the way the accelerator pedal is released (quickly or slowly) during deceleration. In this way, unnecessary upshifts are prevented during deceleration, matching the driver's intentions. In addition, unintended downshifts are prevented when accelerating the vehicle again, achieving smooth acceleration." So, unless you can learn to abide by the above rules as to how you "manage" the accelerator pedal the 1-2 second downshift delay will remain a potential problem. |

Replying to: exler (Jan 14, 2009 12:32 pm) During coastdowns from 40-30MPH, or 10-0MPH resulting from a simple lift throttle action, followed quickly by FIRM re-application of pressure to the gas pedal was the specific requirement, but even that was not predictably repeatable. It was clear to me that most of the time these occurances would be, might be, totally unexpected, apparent happenstance. My reading of post 698 regarding the upcoming 2010 RX350 indicates clearly that Toyota and Lexus transaxles still have this problem. The statement infers that if the driver is aware in advance that a quick move to re-acceleration is probable the the driver can indicate so to the TCM via actions with the accelerator pedal. If you KNOW, in advance, that you will require QUICK acceleration immediately AFTER a short period of coastdown then the appropriate action is to RAPIDLY lift, FULLY lift, the accelerator pedal. That specific action will indicate to the TCM that it is NOT to command a tranasaxle upshift as it would normally for a coastdown period. The procedure might require some practice but can be accomplished. But... That does not addess the times, situations, wherein the driver may not be aware of the "future". So my advice would be to only purchase Toyota/Lexus FWD or F/awd vehicles with manual/sequential shift capability. Then, each and every time you enter a coastdown period simply downshift the transaxle manually(***) in preparation for the potential of the need for a quick re-acceleration action. *** But never, NEVER downshift absent being sure, CERTAIN sure, of the road surface being highly TRACTIVE. "This" is a FWD and/or F/awd and so engine compression braking, even slight engine compression braking, due to a downshift can lead too quickly to loss of control and a serious accident.
