ZF adaptations
ZF adaptations
In the spirit of proactive maintenance and in the hopes of curing the infamous "lurch", I just had the ZF transmission flushed/filter changed and software updated with adaptations cleared on the ZF in my 2004 3.0 liter S-Type.
I've heard it said that one should drive gingerly after having the adaptations cleared so the transmission can "learn" my driving style, but my shop didn't send me away with any special instructions.
Can anyone explain in layman's terms what the adaptations are adapting to in my driving style and how best to help the process be successful? Or is there a TSB on it out there?
Thanks in advance.

I was told when mine was reset .
1,do not use sport mode
2,do not use kick down
3, drive conservatively .
for around 400miles.
the trans needs to retrain the torque converter lockups,
and cluch release valves for each gear .

When working at the dealer I had a rep from jaguar come out on road test with me, he wanted me to do the following, which is near impossible on a public highway.
No sport mode, accelerate from rest up all the gears, keeping the revs below 2000, and below 1500 if possible.
Once it reaches top gear, let it coast down to a stop, without using the brakes, so it downchanges into each gear. Repeat this as many times as possible. 2 times minimum.
then advise the customer to drive gently and keeping rpm low for the next 200 miles.

It sounds like the transmission software isn’t so much adapting to the driver so much as adapting itself to the hardware.
I typically shift manually from 2-5, using D/6 for overdrive on the highway, in part because I want the torque when/where I expect it, in part because I like cornering fast and braking with torque assisting, but also because I drove a manual for 30 years and it “feels” better and more engaging. Besides, the V6 power only really kicks in above the programmed shift points.
Anyway, for the last 100 miles, I’ve kept the car in D and driven it as conservatively as I can given modern traffic conditions in a busy, congested metropolitan region. I hope this is enough, but if the software is actually adapting to the driver’s style, then it’s certainly not *my* style.

Originally the adaptations could be cleared (or new firmware loaded if there was any, not that there was) and that was it. So you wanted to re-train the clutches/solenoids inside the trans plus it learns your driving mannerisms.
Later they added IDS/SDD software that would do the clutches bit. They now drive the car after clearing/reprogramming and a passenger with IDS/SDD can see the gear changes and the clutches as they apply/learn.
Not much need to drive it specially.
However, if your guys didn't use a modern IDS/SDD (or IDS/SDD at all) then you may want to be nice to the trans for a while else it may "lurch".
I like to drive sedately (well, somewhat) in D but for really spirited stuff select Sport. By now it's got very different behaviour in S than D.
It has another set of maps for Cruise and does the best it can regardless of your habits.
