Use the Cup Plug to block the Reverse passage in the case. (the passage to the right of the Center Support Bolt) I recommend using some type of Retainer Compound on the OD of the cup plug & let it set overnight.

Is this a good thing to do if you have to pull the valve body for any reason?
I have to pull my VB to replace the plastic piston on the VB.
Any other suggestions while I am in there?
Its an 86 C20 with 57k OG miles. Never been apart. Shifts great, just no engine braking in 2nd only.
