How do you tell if they're cast or steel?

Sadly, the large metal sealing ring is broken, looks like the box got dropped and it cracked. Would it be ok to re-use the old sealing ring with a new o-ring?
Your new rings look to be cast, Yellow paint marks on the edges equals "Off Shore" JUNK!

It's tough to tell cast apart from steel.....I run the Trans Go 700 PHK Pump Rings in EVERY 700/200/4L60E build! Best $8 dollars you will ever spend!

Reuse your old support, Run the shiny side toward the O-Ring.

Re: 700R4 build thread.

Thanks! I've got the transgo unbreakable rings on the way.

I REALLY appreciate the info!

EDIT:

I emailed the seller of my pump kit, asking about whether the rings were steel or cast iron. Here is their reply, which makes me want to laugh and cry at the same time.

Because they are attracted to a magnet I believe they are steel.

The lesson here is to only buy known reputable parts from known reputable sellers.

I'm betting this one had a trans-go spring between the 2nd Acc piston and the separator plate - given the pic below from when I opened it up back in August.

Your above comment didn't soak into my head until after I'd driven out the 2nd Accumulator pin and staked the ball from the Sonnax Pinless kit into the housing. I didn't think it would be a good idea to try and go back, so I went ahead with the Sonnax Pinless piston and the original unbroken spring, as per Sonnax's '94-Later instructions (spring in the Accumulator body, then Piston with dome toward the separator plate). Do you see any issues with that setup?

FWIW, the Trans-Go springs are a tight fit into that Sonnax piston, no wonder they can break.

Re: 700R4 build thread.

clinebarger, thanks a million for this wealth of knowledge. Having installed many trans kits in the past, and not been happy with the results, I was able to decipher what to use where and how to set it up all in one shot... Thanks to this topic. Just finished building my first 383 and dove right into the transmission. Upshifts, downshifts, etc, it all works perfectly. Im still grinning ear to ear from the first test drive 2 hours ago!

Re: 700R4 build thread.

Unfortunately, Clinebarger is no longer around. I have a 700r4 and purchased an FTI unit in the range you are looking for. I like it.
