Reset Adaptive Transmission Control Question

I have ALPINA Flash auto trans.I already have Redline ATF D4 in trans. So I decided to flush out and put fresh Redline ATF D4 again few yrs later on stock trans. Is it recommended to do the reset with key on position and hold pedal to floor for 30 seconds or should I not reset ?Is there a negative effect if done or is there a learning curve it has to do all over again?

With holding pedal you reset pedal adaption. No more no less. Has nothing to do with Auto trans adaptations for which you need dealer equipment or Launch or similar.
To your original question should trans adaptation to be reset with the fluid change. The answer depends on the trans performance. If you have no complains how it shifts don't reset it.

No problems.I looked at a diy on trans while back and he stated:
Step 7 - Finishing Up

It would probably be a good idea to reset the Adaptive Transmission Control. This is done by switching on the ignition (but not the engine), holding down to the floor the gas pedal for 20 seconds, releasing the gas pedal, switching off the ignition and then youíre done. Itís disputed whether this works however a few people have tried this with good results including myself. (Thanks Dack for this one!)

Yes it can. If you believe pressing the pedal for 20 seconds resets the 6AT adaptations, then look in your rear view mirror at the same time; you'll see flying pigs and an alive Michael Jackson.
