To improve 2nd to 3rd shift delay or "flaring." Can be installed without removing the transmission
This is an improved factory upgrade for the older 722.3 transmission valve body. The accumulator parts you install are Genuine Mercedes. The intent of this upgrade is to improve the transition from 2nd to 3rd shift by adjusting the pressure in the K1 drum. As long as your clutches are not worn out or the seals are good in your K1 drum, this can remove the delay when shifting between second and third gear.
