E40D overhall/servo snap ring and plate missing

<TABLE><TBODY><TR><TD vAlign=top width="100%">I've got a 95 F350 4x4 powerstroke diesel with a E40D automatic tranny. I'm rebuilding the trans and when I got to the servo the snap ring and the plate below the the snap ring were missing. I'm wondering why the trans still worked good even though they weren't there. The trans shifts fine. Could it be that they put a shift kit in it last time it was rebuilt? How can I tell if it has a shift kit? I'm concerned that if I put a snap ring and plate in it now that it might not shift right once I'm through rebuilding it. Do you discard the snap ring and plate when you put a shift kit in it, or was it just left out?

I though I answered this in the axle forum. Maybe you missed it.

Here it is again:
Are you talking about the intermediate band shift servo, if so some have snap rings and some don't.

NOTE: On some models, the intermediate band servo has a snap ring as a retainer.

Without a snap ring you remove it like this:
Using a plastic or rubber headed hammer, gently tap on the intermediate band servo assembly piston. (The downward force will compress the spring. The upward momentum of the spring will then force the assembly to be released from the case bore.) Remove the servo piston.
