Is one if these "Adaptation/Software update/reprogramming of transmission" required to do when changing transmission oil at every interval ?
Is there possibility of trial version of this software to be installed in TCU ? If yes, how to check to avoid this.
Why i should do software update or whatever called to my car's transmission ? Once this was done by manufacturer. What happens ?
Transmission is not smooth when it shifts from 2 to 1. As far as i know, this is known issue with 722.9 transmission. Only way is o get the TCU updated, okl changed or conductor plate replaced.

There is no adaptation necessary when changing trans. oil.

Where did you get your information?

Heard from someone.

What about transmission software update to fix shifting issue from 2nd to 1 when rolling the car to stop?

Maj. Dundee

Heard from someone is useless because there is nothing to back it.

I had the same exact issue and a fluid & filter change corrected the issue. Do not drain the trans. pan as there is no fill tube. Fluid is inserted into the pan by using a pump.
