I'm happy to be corrected but I thought that it was a bit of a myth that the transmission could be reset in this way. Probably more to do with accelerator position sensor if anything. Certainly the correct adaptation process is far more complex and requires hooking up to the correct diagnostic tool followed by a series of specific driving procedures.

I have a manual gearbox, so not sure on automatics.

I think that reset procedure is for the throttle body and not the gearbox. |

The relearning process is a time consuming one, as the temperatures of the engine and gearbox must be over a certain temperature, hardly reached during day to day driving cycles.

I think we are talking about 2 different things here.

Yep, indeed, there are three things that can be reset on the box fuzzy logic:

A technical question out of leftwing, or rather the rear.

Yes I had an auto FL1. I live in a village at the bottom of a long hill. I noticed that the FL1 behaved totally differently coming down that hill (in terms of engine braking etc) depending upon my driving style over the previous few miles. My FL2 doesn't seem to react this way. However, my wife's Suzuki Swift (6 speed auto with a torque convertor) does seem to exhibit some of these "recent driving style" characteristics on the same hill. 3 x FL1 2 manual + 1 auto 5 x FL2 4 manual + 1 auto Now Discovery Sport P250 MHEV SE |

The box "advertising" is naming this mode "uphill/trailer". Although there is no specific "map" for towing or/and a caravan is attached, the gearbox is heavily relying on the information received from the engine module, especially the torque generation reported by the ECM. Based on that, it will adjust the changing points, the speed of changing and the amount of TCC slipping. |

My auto seem to hang on to lower gears for longer than normal under 2 conditions.

Interesting as I'm finding our car can change down a bit abruptly at times Usually coming to an intersection slowly braking

Let's hope it's not too late for some components... Usually, such behavior is when the valve block, meaning one or more of its solenoids are on their way out.
