So on installation of the new 4 Tube Seals i noticed a slight difference in design,it Fitted much more loose inside the diameter hole where the original seals did fit before.initially it was hard at first to keep them in position till i installed the mechatronics valve body bck & all seated well and Bridge seal was perfect fit.Torqued Bolts to spec & refilled with manufactures spec oil,i then reset transmission adaptions via Inpa (very important todo after replacing seals otherwise transmission ecu will still have old pressure adaptions stored ).transmission is shifting much more smoother than before and while your there clean you pressure/valve solenoids with electrical cleaner.my bmw is a E60 530i with 270 000km and now is shifting magically.hope this helps anyone questioning where or not this seal kit is worth it,Yea its definitely worth it.
