The headache at the time was that everything was mechanically controlled, and that created some problems. "It's been existing in this market before in the '50s. "In Europe, it has been used as long as I've been employed by the company, and that's over 40 years," he says. Peter Blonde has been called "the Godfather of Adaptive Loading." But as Volvo's driveline expert he's quick to point out the 6x2 tandem concept is in no way new. I have no complaints about DS, other than the fact that I have no clutch pedal.A close working relationship with customers has helped drive an evolving series of technologies, including Adaptive Gearing and Adaptive Loading, that maximize efficiency while defying old conventions. It's a bit wonky in D as I feel that it upshifts too soon and downshifts late, sometimes luggung, but that's like every automatic transmission I've driven from any manufacturer and I just figured that's BMW's attempt to stay in a tall gear and maximize fuel economy. I never reset my transmission adaptations, and my car behaves great in DS. When you press the pedal to the floor, doesn't that activate the water pump and start the cooling system bleeding procedure? I'm also not convinced that's the correct procedure. I'm not convinced this is absolutely necessary. The reason why i am saying this is i dont want to give other people false hopes that all they have to do is this reset. If you still notice that you have bad shifts then its the solenoids.īecause adaptation reset is temporary and doesnt fix anything. When you buy a used car you need to replace the transmission fluid and filter first if you notice weird shifting. Otherwise they would call them transmission fixes. Transmission adaptations are not a fix for anything. If you have not fixed a root cause this smoothness does not last and will return. ( If you drive normally, it can take faster if you do the drive procedure) This learning process takes a long time to complete as you drive. The reason why you feel a better response is because the solenoids and clutch pressure plates now operate at different pressures as the transmission control module is trying to re learn the positions. Transmission adaptions should not be performed unless you have replaced components such as valve body. There is more to this and its not this simple. you are missing out if you don't.ĮDIT: To do this, you turn the car into Accessory mode and hold the gas pedal to the floor for one minute. If you bought a used car, you must absolutely do this. It is so responsive and the shifting is so much smoother and actually shifts where it's supposed to. It doesn't even feel like the same car any more. What a tremendous difference that made while driving in DS. I read about resetting the adaptive transmission. Doesn't look like the previous owners did any sort of preventative maintenance.Īnyways, doing all this, the car ran much better, but the gear shifting was kind of crappy. I've done a lot of tune up on it (plugs and coils, air filter, cabin filter, cleaned VANOS). Recently purchased a 2011 328i with 78,000 miles. I just had to post something about this because I didn't learn about it until the other day.
