You are in the Ford Explorer Forum. Your Hosts are steve_ & tidester

Those of us in the US are remembering Memorial Day with our long weekend and the usual weekday commentary is getting sidetracked a bit (I guess we missed Victoria Day). Anyone who wants to talk about the Explorer or Mountaineer and not just transmission nuances, feel free to hop in with a new thread. Steve, Host |

Please don't twist my words. Here's what I said: "The above quote is believed by many, but is simply not true. The Explorer 5-speed auto transmission has no feature that recognizes or adapts to a person's driving behavior. After a few thousand miles, it will execute a given shift the same for Granny as it will for anyone else." This is based on input from the engineers who designed and calibrated the transmission. I understand how many have been mis-led by misinformation. It's fine with me if they want to continue to believe it. If anyone cares to understand the reality of how the transmission adapts, I'll be glad to offer it up. I respect your position Steve. I don't think this transmission discussion has provented anyone from posting on another subject. I hope you respect mine as well. I'm loyal to Ford, and get a bit riled when I read statements that I know to be incorrect. I would think that Edmunds would also be interested in the integrity of the posts on their forum. Peace?

Replying to: lateralg (May 28, 2005 9:02 pm) Personally, I just like to see more in the way of back up than "based on input from engineers." Not that I don't believe you, and just because it's on the net doesn't mean it's true, but I'd like to see some more in the way of back-up documentation or explanation. So feel free to offer it up, and we'll wrap it up in time to return to the usual commentary in here when the regulars and would be owners get back from holiday. And I am a bit confused - are you ok that some transmissions do adapt for different drivers, just not the ones in the Explorer? Steve, Host |

It's very easy to obtain back up. ANT, with his insider knowledge of FOMOCO, only has to pick up the phone & call Transmission Engineering in Livonia. I look forward to his report on the call. It does appear that some transmissions adapt for different drivers. I've been addressing the false claim that Explorer transmissions do. Unless more misinformation appears, I'm done with this topic.

| Maybe lateralg is not differentiating between the transmission itself and the transmission controls. The mechanical box does not have any ability to adjust, but the software in the control computer apparently does. | |

"but the software in the control computer apparently does." The software does adjust, but NOT to the driver. It leaves the plant with optimal shift duration data stored in memory. As the computer experiences shifts, it compares the actual duration of the shift with optimum. It adjusts engagement and release timing and pressures to bring the shift duration closer to optimum. This can take several occurrences of a given shift before optimum timing is achieved. Note that a "given shift" is much more than a 1-2 shift. It's a 1-2 shift at various throttle openings and RPM. Same is true for the 2-3, 3-4, 4-5, 5-4,4-3,3-2,2-1, N-D, R-D shifts. A big reason for this strategy is that the transmission automatically adjusts for clutch and band wear as the vehicle ages. Please do not attempt to twist the above into any resemblance of adapting to DRIVER habits. It simply does not! Steve, the only way I know to do what you propose is to post the name and number of an engineer at Transmission Engineering in Livonia. That isn't appropriate. If ANT14 has the inside track that's implied in his posts, then he can get the correct information with no more than 3 phone calls.

"Steve, the only way I know to do what you propose is to post the name and number of an engineer at Transmission Engineering in Livonia. That isn't appropriate." Considering Ford monitors these boards (and I know that as a fact). I wouldn't recommend posting such information. Fords legal representatives will get the information, issue a "John Doe" search and discovery towards Edmunds to release the IP of the person posting the claim, then file another search and discovery towards the IP provider, track down the informants stating such claims, and they can actually lose their jobs and face legal recourse for stating such claim which otherwise they wouldn't be able to release because it's considered insider espionage. Specially considering it's information that can be detrimental over an issue in technnology Ford has claimed for many years to have offered, has included information over it to the media and boasted over it, mention it in the owner's manual, etc.... which could lead to private lawsuits on the side of Explorer owners. And all this because one or 2 engineers conclude otherwise. So it's best to let the issue rest at this point without opening Pandora's Box.... |

Replying to: lateralg (May 29, 2005 10:28 am) Ok, if I take my tranny in for a reflash, the optimal shift duration data will get changed and the tranny will take a while to adjust. If I disconnect the battery to cause the tranny to relearn, aggressive or mild driving will just affect the time it takes for the tranny to figure out the optimal shift duration, based on throttle and rpm stuff. Or am I putting words in your mouth? I think we're about done here... Steve, Host |
