TC Chain / Throttle Adaptation

[jsoto]

This may be too early to tell, but is there any sort of adaptation/settling of a new chain in the Transfer Case. Adaptations were reset as well, as I did unplug the battery to do something.

Anyhow, I've only have like 25'ish miles on it on my initial testing, and I'm sorta getting a lurch from 1-2. Picked on on it like 3X. It's not on every time - but the lurch was noticable enough post /On the highway upshifting, sofar, all good, but while accelerating at highspeed, the rpm's seems to have went a bit higher than ~normal~ before upshifting - seat of the pants feeling/which lead to the quick glance on the cluster.

pre-x-drive. No tc adaptation done

Pulling the battery doesn't reset any adaptations - or at least not any long term ones. In any module.

There aren't any adaptations for the pre-xDrive TCs - there's no VTG module controlling it.

Sounds like the gearbox is struggling to get used to the new driveline setup. Might sort itself out with time, or perhaps a EGS module (trans) adaptation reset is called for, although this should really only be done when the trans has been worked on (new mechatronic or driveline components).
