722.6 Solinoid Dust Covers
 

The 722.6 Conductor Plate has 2 "Dust" Covers to help the flow of ATF to the Solinoids. When I replaced my Conductor Plate I found the 2 covers missing and assumed a previous trans service neglected to put them back. Now I am wondering if all 722.6's came with the Dust Covers and if I should leave mine off?
I ordered one from MB and installed it (one is NLA) and the Valve Body/Conductor Plate assy went back in without any trouble. Now I'm wondering if I should have put the dust covers back on? I can't see how fitting the cover would cause damage but I'd hate to find out the hard way the covers were left off for a reason.
Any ideas? Maybe I'm over-thinking this issue?
TIA

The covers were installed to prevent the exhausting oil from foaming the oil dribbling downwards from the rotating assembly.

You can probably find them at an oldschool transmission shop - ask for them not for mercedes but for dodge charger/magnum or old jeep cherokee etc. they use the same transmission as our cars.
