You can, but it is not a good idea. And you should never use a regular "rebuilders" type metal seal. The aftermarket companies, at least at one time, made moly faced sealing rings. Those "could" be used. But I'd advise you to use scarf cut Teflon seals. Usually aftermarket companies sell the seals for $15 or so for the set.

You may even find some in a TH350C/TH250C kit, as those late model lockup units (that's what the "C" denotes) often had the blue Teflon seals.

A good transmission parts house, like "Whatever It Takes", will have those kits fairly cheap (called a "short ring" kit, or "paper, rubber, rings, and seals" kit, or "overhaul" kit), maybe $20-$40 or so.
