700r4 Pump o rings and washers?

[68longhorn]

I am replacing the front pump seal on a 700r4. The gasket set came with washers and o rings for the pump bolts but no instructions on which order the go. I assume I slide the washer on first followed by the boring? The original bolts had rubber coated washers it appears.

Are the washers copper or aluminum? If so, they go on without any o'rings. I think the o'rings were on later pumps.

With a 700R4 there is only one pump hole that is drilled all the way through that has the potential for leaking. However, all the bolts got o-ring seals. Earlier transmissions like the TH30 has gaskets and not o-rings. The bolts were flat. 700R4 there is a groove in the bolt for the o-ring. Common for an aftermarket set to have both. I've seen many transmissions with both installed. Gasket against the pump and o-ring on the bolt. From the factory, the 700R4 only had the o-ring
