Well then I am not sure why he was asking but that would mean you do not have a sleeved drum . I do know with the sleeved drum if you are not real carefull you can cut ot damage the overun clutch Oring.
As for the burned clutches do not reuse them as they will not hold well even though overun frictions are not a critcal set its better to use new ones or at least ones that are not burned, Since you do not have a sleeved drum he may have planned to suggest you change all the pistons to the steel type with the molded permanet seals they are and easier install and a very good upgrade,
Below two of the three are shown.

I was asking because I did not know the answer. Pretty simple huh?
I have seen builders try to use lipseals in conjunction with a machined piston / sleeved drum, it is a simple matter of them not understanding what they were looking at. A "Sleeved" drum is a drum that has been reinforced with a steel collar we call a sleeve. It will be installed in the area of the drum that the Overdrive piston inner seal rides. In a sleeved drum this seal is replaced with a large O-ring instead of a lip seal because the ID of the Overdrive piston would have to be machined to accomodate the sleeve.
Now, as far as using upgraded pistons. Sure they are a terrific upgrade. But not at this point of this particular build. If the OP has gotten this far, as far as running it and removing it for diagnosis and repair... then upgraded pistons are a mute point. They and other modifications should have been weighed pior to the original build. That is why I would not advise changing these pistons out at this point in the game.
It's kinda like telling a guy.. "Hey did you know that if you bought those Jesel Rockers they would be better than the Factory Rockers." The factory rockers are just fine until they fail. That might not ever happen in this case, but it might happen tomorrow.

my 3-4 piston & piston forward clutch is the steel typ with the seals perment bonded.
I'm checking on frictions clutches now pretty much putting all new seal gaskets & bushings now plus grading my input gear to bear instead of bushing.
