722.3 K1 Accumulator Upgrade Kit w/ Extras

From 1981 to 1990 transmissions only. 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 up through 1990. Later models were revised and this upgrade is not required. The accumulator parts you will  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.
