You said that with the sonnax piece you would feel significant 3-2 and 2-1 downshifts when slowing.
I have no idea if mine have the sonnax piece. In OD it downshifts smoothly into every gear. But in D it will downshift very hard 3-2. But still smooth 2-1.
What is the explanation on this?
Its a built 700r4.

In summary it appears with a 700R4 that [D3] is the recommended position on the track, but with the 4L60(E) it is [D4], unless this rare Sonnax valve was installed.
