If bowden adjustment makes little to no difference, then it may be damaged, or disconnected in the pan.

the bowden senses how hard you are pressing on the pedal, and holds gears longer when floored/heavily accelerating, and shifts rapidly if the pedal is barely pressed.
so.
tightening the bowden will keep the lower gears engaged longer and prevent rapid shifts.
HOWEVER, if you have it tight, and you barely step on the pedal to get going, because your alda is out, and the car moves so well at part throttle, or if you floor it, you get a huge cloud of black smoke... then the transmission is doing what it's supposed to. it's upshifting based on your throttle position.
Thanks Vstech. Nice thinking. I like it. I'm going to try a valve body. A tranny guy said if bowden cable is tight and it still wont stay in lows gears its a collpsed spring behind the bowden. This guy has been rebuilding trans for 35 years and knows Mercedes and just did my 1992 722.4 rebuild . So now i have a 722.3 and 722.4 transmission cars with same problem -- no kick down and upshifting right away no matter how i adjust it. So hopefully the valve body is it and that will explain alot . I'll post and update.
