Back then, I had a feeling, it is mainly about getting used to and understand the car's TCU.

2) If I understand it correctly, with the 4.44 in, the car will be faster and more durable, but - and that is more important to me - will the shift changes still be as gentle and imperceptible as they are in the 3.54? Also will the stock 3.54 Economy mode operate properly?

If there is one thing, the stock 3.54 is really doing fine. It is creating the illusion that you are not driving car, but piloting a plane.

Thank you,

1) Ouch, are you 100% sure ? So, if I can shift to 1st, 2nd and R, I can safely exclude solenoid A option?

Yes, they all need the same solenoid and line pressure.

I don't know about being faster; you would have to ask somebody that has done the swap. Mine is a VTD with the lower gearing, but it will be more durable, and yes, the same TCU controls the 4.44 gearbox the same as the standard, and the Economy mode still works.
